Cleaner database error handling and fixes.

Add comprehensive remote authentication system allowing users to log in from one device by authenticating from another trusted device. Features include:

- Proof of Work (PoW) protection using PBKDF2-SHA512 to prevent abuse
- Simple pairing codes (3 words) protected by dynamic PoW difficulty
- Autocomplete pairing code input with error checking
- Real-time WebSocket communication between devices

Unlike device addition links and reset links with QR codes that only allow adding an authentication method, and that work offline over the duration of several days, this mechanism is strictly online, with 5 minute time limit.

-# PassKey Auth API Documentation
-
-This document lists the HTTP and WebSocket endpoints exposed by the PassKey Auth
-service and how they behave depending on whether a dedicated authentication host
-(`--auth-host` / environment `PASSKEY_AUTH_HOST`) is configured.
-
-## Base Paths & Host Modes
-
-Two deployment modes:
-
-1. Multi‑host (default – no `--auth-host` provided)
-   - All endpoints are reachable on any host under the `/auth/` prefix.
-   - A convenience root (`/`) also serves the main app.
-
-2. Dedicated auth host (`--auth-host auth.example.com`)
-   - The specified auth host serves the UI at the root (`/`, `/admin/`, reset tokens, etc.).
-   - Other (non‑auth) hosts show a lightweight account summary at `/` or `/auth/`, while other UI routes still redirect to the auth host.
-   - Restricted endpoints on non‑auth hosts return `404` instead of redirecting.
-
-### Path Mapping When Auth Host Enabled
-
-| Purpose | On Auth Host | On Other Hosts (incoming) | Action |
-|---------|--------------|---------------------------|--------|
-| Main UI | `/` | `/auth/` or `/` | Serve account summary SPA (no redirect) |
-| Admin UI root | `/admin/` | `/auth/admin/` or `/admin/` | Redirect -> auth host `/admin/` (strip `/auth`) |
-| Reset / device addition token | `/{token}` | `/auth/{token}` | Redirect -> auth host `/{token}` (strip `/auth`) |
-| Static assets | `/auth/assets/*` | `/auth/assets/*` | Served directly (no redirect) |
-| Unrestricted API | `/auth/api/...` | `/auth/api/...` | Served directly |
-| Restricted API (admin,user,ws namespaces) | `/auth/api/{admin|user|ws}*` | same path | 404 on non‑auth hosts |
-| WebSocket (register/auth) | `/auth/ws/*` | `/auth/ws/*` | 404 on non‑auth hosts |
-
-Notes:
-- “Strip `/auth`” means only when the path starts with that exact segment.
-- A reset token is a single path segment validated by server logic; malformed tokens 404.
-- Method and body are preserved for UI redirects (307 Temporary Redirect).
-
-## HTTP UI Endpoints
-
-| Method | Path (multi‑host) | Path (auth host) | Description |
-|--------|-------------------|------------------|-------------|
-| GET | `/auth/` | `/` | Main authentication SPA (non-auth hosts show an account summary view) |
-| GET | `/auth/admin/` | `/admin/` | Admin SPA root |
-| GET | `/auth/{reset_token}` | `/{reset_token}` | Reset / device addition SPA (token validated) |
-
-## Core API (Unrestricted – available on all hosts)
-
-Always under `/auth/api/` (even on auth host):
-
-| Method | Path | Description |
-|--------|------|-------------|
-| GET | `/auth/restricted/` | Authentication UI for iframe embedding (supports `?mode=login` or `?mode=reauth`) |
-|--------|------|-------------|
-| POST | `/auth/api/validate` | Validate & (conditionally) renew session |
-| GET | `/auth/api/forward` | Auth proxy endpoint for reverse proxies (204 or 4xx) |
-| POST | `/auth/api/set-session` | Set cookie from Bearer token |
-| POST | `/auth/api/logout` | Logout current session |
-| POST | `/auth/api/user-info` | Authenticated user + context info (also handles reset tokens) |
-| POST | `/auth/api/create-link` | Create a device addition link (reset token) |
-| DELETE | `/auth/api/credential/{uuid}` | Delete user credential |
-| DELETE | `/auth/api/session/{session_id}` | Terminate a specific session |
-| POST | `/auth/api/user/logout-all` | Terminate all sessions for the user |
-| PUT | `/auth/api/user/display-name` | Update display name |
-
-## Restricted API Namespaces
-
-When `--auth-host` is set, requests to these paths on non‑auth hosts return 404:
-
-| Namespace | Examples |
-|-----------|----------|
-| `/auth/api/admin` | `/auth/api/admin/orgs`, `/auth/api/admin/orgs/{uuid}` ... |
-| `/auth/api/user` | Segment prefix – includes `/auth/api/user/...` endpoints (logout-all, display-name, session, credential) |
-| `/auth/api/ws` | (Reserved / future) |
-
-## WebSockets (Passkey)
-
-| Path | Description | Host Mode Behavior |
-|------|-------------|--------------------|
-| `/auth/ws/register` | Register new credential (new or existing user) | 404 on non‑auth hosts when auth host configured |
-| `/auth/ws/authenticate` | Authenticate user & issue session | 404 on non‑auth hosts when auth host configured |
-
-## Redirection & Status Codes
-
-| Scenario | Response |
-|----------|----------|
-| UI path on non‑auth host (auth host configured) | 307 redirect to auth host; `/auth` prefix stripped |
-| Reset token UI path on non‑auth host | 307 redirect (token preserved) |
-| Restricted API on non‑auth host | 404 |
-| Unrestricted API on any host | Normal response |
-| No auth host configured | All hosts behave like multi-host mode (no redirects; everything accessible) |
-
-## Headers for /auth/api/forward
-See `Headers.md` for details of headers returned on success (204).
-
-## Notes for Integrators
-1. Always use absolute `/auth/api/...` paths for programmatic requests (they do not move when an auth host is introduced).
-2. Bookmark / deep links to UI should resolve correctly after redirection if users access via a non-auth application host.
-3. Treat 404 from restricted namespaces on non-auth hosts as a signal to direct users to the central auth site.
-
-## Environment & CLI Summary
-| Option | Effect |
-|--------|--------|
-| `--auth-host` / `PASSKEY_AUTH_HOST` | Enables dedicated host mode, root-mounts UI there, restricts certain namespaces elsewhere |
-
----
-This document reflects current behavior of the middleware-based host routing logic.

Caddy.md

@@ -1,64 +0,0 @@
-## Caddy configuration
-
-We provide a few Caddy snippets that make the configuration easier, although the `forward_auth` directive of Caddy can be used directly as well. Place the auth folder with the snippets where your Caddyfile is.
-
-What these snippets do
-- Mount the auth UI at `/auth/` proxying to `:4401` (auth backend)
-- Use the forward-auth interface `/auth/api/forward` to verify the required credentials
-- Render a login page or a permission denied page if needed (without changing URL)
-
-Your backend may not use authentication at all, or it can make use of the user information passed via `Remote-*` headers by the authentication system, see [Headers.md](Headers.md) for details.
-
-### 1) Protect the full site (auth/all)
-
-Use this when you want “login required everywhere” which is useful to protect some service that doesn't have any authentication of its own:
-
-```caddyfile
-localhost {
-    import auth/all "" {
-        reverse_proxy :3000  # your app
-    }
-}
-```
-
-The auth/all protects the entire site with a simple directive. Put your normal setup inside the block. In this example we don't require any permissions, only that the user is logged in. Instead of `""` you may specify `perm=myapp:login` or other permissions.
-
-It is possible to add your own `handle @matcher` blocks prior importing `auth/all` for endpoints that don't require authentication, e.g. to exclude `/favicon.ico`.
-
-### 2) Different areas, different permissions (auth/setup, auth/require)
-
-When you need a more fine-grained control, use the auth/setup and auth/require snippets:
-
-```caddyfile
-localhost {
-    import auth/setup
-
-    @public path /.well-known/* /favicon.ico
-    handle @public {
-        root * /var/www/
-        file_server
-    }
-
-    @reports path /reports
-    handle @reports {
-        import auth/require perm=myapp:reports
-        reverse_proxy :3000
-    }
-
-    # Anywhere else, require login only
-    handle {
-        import auth/require ""
-        reverse_proxy :3000
-    }
-}
-```
-
-Note: We use the `handle @name` approach rather than `handle_path` to prevent the matched path being removed out of upstream URL. Unlike bare directives, these blocks will be tried in sequence and each can contain what you'd typically put in your site definition.
-
----
-
-## Override the auth backend URL (AUTH_UPSTREAM)
-
-By default, the auth service is contacted at localhost port 4401 ("for authentication required"). You can point Caddy to a different by setting the `AUTH_UPSTREAM` environment variable for Caddy.
-
-If unset, the snippets use `:4401` by default.

Headers.md

@@ -1,17 +0,0 @@
-## Headers your app receives
-
-When a request is allowed, the auth service adds these headers before proxying to your app (e.g., the service at `:3000`). Your app can use them for user context and authorization.
-
-| Header | Meaning | Example |
-|---|---|---|
-| `Remote-User` | Authenticated user UUID | `3f1a2b3c-4d5e-6789-abcd-ef0123456789` |
-| `Remote-Name` | User display name | `Jane Doe` |
-| `Remote-Org` | Organization UUID | `a1b2c3d4-1111-2222-3333-444455556666` |
-| `Remote-Org-Name` | Organization display name | `Acme Inc` |
-| `Remote-Role` | Role UUID | `b2c3d4e5-2222-3333-4444-555566667777` |
-| `Remote-Role-Name` | Role display name | `Administrators` |
-| `Remote-Groups` | Comma‑separated permissions the user has | `myapp:reports,auth:admin` |
-| `Remote-Session-Expires` | Session expiry timestamp (ISO 8601) | `2025-09-25T14:30:00Z` |
-| `Remote-Credential` | Credential UUID backing the session | `c3d4e5f6-3333-4444-5555-666677778888` |
-
-Note: Any incoming `Remote-*` headers from clients are stripped by our [Caddy configuration](Caddy.md), so that apps can trust these values.

-# PasskeyAuth
+# Paskia
 
-A minimal FastAPI WebAuthn server with WebSocket support for passkey registration. This project demonstrates WebAuthn registration flow with Resident Keys (discoverable credentials) using modern Python tooling.
+![Login dialog screenshot](https://git.zi.fi/leovasanko/paskia/raw/main/docs/screenshots/login-light.webp)
 
-## Features
+An easy to install passkey-based authentication service that protects any web application with strong passwordless login.
 
-- 🔐 WebAuthn registration with Resident Keys support
+## What is Paskia?
-- 🔌 WebSocket-based communication for real-time interaction
-- 🚀 Modern Python packaging with `pyproject.toml`
-- 🎨 Clean, responsive HTML interface using @simplewebauthn/browser
-- 📦 No database required - challenges stored locally per connection
-- 🛠️ Development tools: `ruff` for linting and formatting
-- 🧹 Clean architecture with local challenge management
 
-## Docs
+- Easy to use fully featured auth&auth system (login and permissions)
+- Organization and role-based access control
+   * Org admins control their users and roles
+   * Multiple independent orgs
+   * Master admin can do everything or delegate to org admins
+- User Profile and Admin by API and web interface
+- Implements login/reauth/forbidden flows for you
+- Single Sign-On (SSO): Users register once and authenticate across your services
+- Remote autentication by entering random keywords from another device (like 2fa)
+- No CORS, NodeJS or anything extra needed.
 
-- Caddy integration: see `CADDY.md` for short, copy-paste snippets to secure your site with Caddy.
+## Authenticate to get to your app, or in your app
 
-## Requirements
+- API fetch: auth checks and login without leaving your app
+- Forward-auth proxy: protect any unprotected site or service (Caddy, Nginx)
 
-- Python 3.9+
+The API mode is useful for applications that can be customized to run with Paskia. Forward auth can also protect your javascript and other assets. Each provides fine-grained permission control and reauthentication requests where needed, and both can be mixed where needed.
-- A WebAuthn-compatible authenticator (security key, biometric device, etc.)
+
+## Authentication flows already done
+
+![Forbidden dialog, dark mode](https://git.zi.fi/leovasanko/paskia/raw/main/docs/screenshots/forbidden-dark.webp)
+**Automatic light/dark mode switching with overrides by user profile and protected app's theme.**
+
+Paskia includes set of login, reauthentication and forbidden dialogs that it can use to perform the needed flows. We never leave the URL, no redirections, and if you make use of API mode, we won't even interrupt whatever your app was doing but retry the blocked API fetch after login like nothing happened.
 
 ## Quick Start
 
-### Install (editable dev mode)
+Install [UV](https://docs.astral.sh/uv/getting-started/installation/) and run:
 
 ```fish
-uv pip install -e .[dev]
+uvx paskia --rp-id example.com
 ```
 
-### Run (new CLI)
+On the first run it downloads the software and prints a registration link for the Admin. The server starts on [localhost:4401](http://localhost:4401), serving authentication for `*.example.com`. For local testing, leave out `--rp-id`.
 
-`passkey-auth` now provides subcommands:
+For production you need a web server such as [Caddy](https://caddyserver.com/) to serve HTTPS on your actual domain names and proxy requests to Paskia and your backend apps (see documentation below).
+
+For a permanent install of `paskia` CLI command, not needing `uvx`:
+
+```fish
+uv tool install paskia
+```
+
+## Configuration
+
+You will need to specify your main domain to which all passkeys will be tied as rp-id. Use your main domain even if Paskia is not running there. All other options are optional.
 
 ```text
-passkey-auth serve [host:port] [--options]
+paskia [options]
-passkey-auth dev   [--options]
 ```
 
-Examples (fish shell shown):
+| Option | Description | Default |
+|--------|-------------|---------|
+| -l, --listen *endpoint* | Listen address: *host*:*port*, :*port* (all interfaces), or */path.sock* | **localhost:4401** |
+| --rp-id *domain* | Main/top domain for passkeys | **localhost** |
+| --rp-name *"text"* | Branding name for the entire system (passkey auth, login dialog). | Same as rp-id |
+| --origin *url* | Only sites listed can login (repeatable) | rp-id and all subdomains |
+| --auth-host *url* | Dedicated authentication site, e.g. **auth.example.com** | Use **/auth/** path on each site |
+| --save | Save current options to database | (only --rp-id required on further invocations) |
+
+To clear a stored setting, pass an empty value like `--auth-host=`. The database is stored in `{rp-id}.paskiadb` in current directory. This can be overridden by environment `PASKIA_DB` if needed.
+
+## Tutorial: From Local Testing to Production
+
+This section walks you through a complete example, from running Paskia locally to protecting a real site in production.
+
+### Step 1: Local Testing
+
+For development and testing, run Paskia without any arguments:
 
 ```fish
-# Production style (no reload)
+paskia
-passkey-auth serve
-passkey-auth serve 0.0.0.0:8080 --rp-id example.com --origin https://example.com
-
-# Development (auto-reload)
-passkey-auth dev            # localhost:4401
-passkey-auth dev :5500      # localhost on port 5500
-passkey-auth dev 127.0.0.1  # host only, default port 4401
 ```
 
-Available options (both subcommands):
+This starts the server on [localhost:4401](http://localhost:4401) with passkeys bound to `localhost`. On first run, Paskia prints a registration link for the Master Admin—click it to register your first passkey.
 
-```text
+### Step 2: Production Configuration
---rp-id <id>        Relying Party ID (default: localhost)
---rp-name <name>    Relying Party name (default: same as rp-id)
---origin <url>      Explicit origin (default: https://<rp-id>)
-```
 
-### Legacy Invocation
+For a real deployment, configure Paskia with your domain name (rp-id). This enables SSO setup for that domain and any subdomains.
-
-If you previously used `python -m passkey.fastapi --dev --host ...`, switch to the new form above. The old flags `--host`, `--port`, and `--dev` are replaced by the `[host:port]` positional and the `dev` subcommand.
-
-## Usage (Web)
-
-1. Start the server with one of the commands above
-2. Open your browser to `http://localhost:4401/auth/` (or your chosen host/port)
-3. Enter a username (or use the default)
-4. Click "Register Passkey"
-5. Follow your authenticator's prompts
-
-Real-time status updates stream over WebSocket.
-
-## Development
-
-### Code Quality
 
 ```fish
-# Run linting and formatting with ruff
+paskia --rp-id example.com --rp-name "Example Corp" --save
-uv run ruff check .
-uv run ruff format .
-
-# Or with hatch
-hatch run ruff check .
-hatch run ruff format .
 ```
 
-### Project Structure
+This binds passkeys to `*.example.com`. The `--rp-name` is shown to users during passkey registration. The `--save` option stores these settings in the database, so future runs only need `paskia --rp-id example.com`.
 
-```
+### Step 3: Set Up Caddy
-passkeyauth/
+
-├── passkeyauth/
+Install [Caddy](https://caddyserver.com/) and copy the [auth folder](caddy/auth) to `/etc/caddy/auth`. Say your current unprotected Caddyfile looks like this:
-│   ├── __init__.py
+
-│   └── main.py          # FastAPI server with WebSocket support
+```caddyfile
-├── static/
+app.example.com {
-│   └── index.html       # Frontend interface
+    reverse_proxy :3000
-├── pyproject.toml       # Modern Python packaging configuration
+}
-└── README.md
 ```
 
-## Technical Details
+Add Paskia full site protection:
 
-### WebAuthn Configuration
+```caddyfile
+app.example.com {
+    import auth/setup
+    handle {
+        import auth/require perm=myapp:login
+        reverse_proxy :3000
+    }
+}
+```
 
-- **Relying Party ID**: `localhost` (for development)
+Run `systemctl reload caddy`. Now `app.example.com` requires the `myapp:login` permission. Try accessing it and you'll land on a login dialog.
-- **Resident Keys**: Required (enables discoverable credentials)
-- **User Verification**: Preferred
-- **Supported Algorithms**: ECDSA-SHA256, RSASSA-PKCS1-v1_5-SHA256
 
-### WebSocket Message Flow
+### Step 4: Assign Permissions via Admin Panel
 
-1. Client connects to `/ws/{client_id}`
+![Admin panel permissions](https://git.zi.fi/leovasanko/paskia/raw/main/docs/screenshots/master-permissions.webp)
-2. Client sends `registration_challenge` message
-3. Server responds with `registration_challenge_response`
-4. Client completes WebAuthn ceremony and sends `registration_response`
-5. Server verifies and responds with `registration_success` or `error`
 
-### Security Notes
+1. Go to `app.example.com/auth/admin/`
+2. Create a permission, give it a name and scope `myapp:login`
+3. Assign it to Organization
+4. In that organization, assign it to the Administration role
 
-- This is a minimal demo - challenges are stored locally per WebSocket connection
+Now you have granted yourself the new permission.
-- For production use, implement proper user storage and session management
-- Consider using Redis or similar for challenge storage in production with multiple server instances
-- Ensure HTTPS in production environments
 
-## License
+Permission scopes are text identifiers with colons as separators that we can use for permission checks. The `myapp:` prefix is a convention to namespace permissions per application—you but you can use other forms as you see fit (urlsafe characters, no spaces allowed).
 
-MIT License - feel free to use this as a starting point for your own WebAuthn implementations!
+### Step 5: Add API Authentication to Your App
+
+Your backend already receives `Remote-*` headers from Caddy's forward-auth. For frontend API calls, we provide a [JS paskia module](https://www.npmjs.com/package/paskia):
+
+```js
+import { apiJson } from 'https://cdn.jsdelivr.net/npm/paskia@latest/dist/paskia.js'
+
+const data = await apiJson('/api/sensitive', { method: 'POST' })
+```
+
+When a 401/403 occurs, the auth dialog appears automatically, and the request retries after authentication.
+
+To protect the API path with a different permission, update your Caddyfile:
+
+```caddyfile
+app.example.com {
+    import auth/setup
+
+    @api path /api/*
+    handle @api {
+        import auth/require perm=myapp:api
+        reverse_proxy :3000
+    }
+
+    handle {
+        import auth/require perm=myapp:login
+        reverse_proxy :3000
+    }
+}
+```
+
+Create the `myapp:api` permission in the admin panel, that will be required for all API access. Link to `/auth/` for the built-in profile page.
+
+You may also remove the `myapp:login` protection from the rest of your site paths, unless you wish to keep all your assets behind a login page. Having this as the last entry in your config allows free access to everything not matched by other sections.
+
+```Caddyfile
+    handle {
+        reverse_proxy :3000
+    }
+```
+
+### Step 6: Run Paskia as a Service
+
+Create a system user paskia, install UV on the system, and create a systemd unit:
+
+```fish
+sudo useradd --system --home-dir /srv/paskia --create-home paskia
+curl -LsSf https://astral.sh/uv/install.sh | sudo env UV_INSTALL_DIR=/usr/local/bin sh
+sudo systemctl edit --force --full paskia.service
+```
+
+Paste the following and save:
+
+```ini
+[Unit]
+Description=Paskia Authentication Server
+
+[Service]
+Type=simple
+User=paskia
+WorkingDirectory=/srv/paskia
+ExecStart=uvx paskia --rp-id=example.com
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Then enable and start, view output for registration link:
+
+```fish
+sudo systemctl enable --now paskia && sudo journalctl -u paskia -f -n 20 -o cat
+```
+

+# Paskia API
+
+For integrating Paskia with your app frontend, see [integration](Integration.md).
+
+## Web Interface
+
+| Method | Path | What it is for | Notes |
+|---:|---|---|---|
+| GET | `/auth/` | User profile page | |
+| GET | `/auth/admin/` | Admin panel | Requires auth:admin (master) or org admin permissions. |
+| GET | `/auth/{token}` | Reset / add credential URL (QR code link) | E.g. `/auth/fun.cotton.fresh.xray.lava` |
+
+### Public JSON API: `/auth/api/*`
+
+| Method | Path | Used for | Notes |
+|---:|---|---|---|
+| GET | `/auth/api/settings` | Paskia configuration | Returns RP info + base paths + session cookie name |
+| POST | `/auth/api/user-info` | Full user profile | Basic information, credentials, sessions, permissions |
+| POST | `/auth/api/logout` | Terminate session and delete session cookie | Signs out of the current site |
+| POST | `/auth/api/validate` | Validate and renew session cookie | Optional query: `perm=` (repeatable), `max_age=` |
+| GET | `/auth/api/forward` | Validate access (Caddy/Nginx) | 204 on success; 401/403 otherwise (HTML if requested) |
+
+The `validate` and `forward` endpoints take query arguments `perm=` and `max_age=` for specific requirements on the validation of the current session.
+
+### User JSON API: `/auth/api/user/*`
+
+| Method | Path | Used for | Notes |
+|---:|---|---|---|
+| PUT | `/auth/api/user/display-name` | Update the user’s display name | Body: JSON `{ "display_name": "..." }` |
+| POST | `/auth/api/user/logout-all` | Terminate all user sessions | Clears current host cookie |
+| DELETE | `/auth/api/user/session/{session_id}` | Terminate one session | Session IDs are server-issued |
+| DELETE | `/auth/api/user/credential/{uuid}` | Delete a credential | Requires recent authentication |
+| POST | `/auth/api/user/create-link` | Create a device-add link | Requires recent authentication |
+
+These are used mostly from the user profile panel and modify the current user.
+
+### Admin API: `/auth/api/admin/*`
+
+Normally only used via admin panel, requires auth admin permissions and can modify any users, orgs and permissions the session has access to.
+
+E.g. Org admin cannot see anything of the other orgs that he has no admin access to. Master admin `auth:admin` can see everything and create and manage orgs.
+
+### WebSockets: `/auth/ws/*`
+
+| Path | Used for | Notes |
+|---|---|---|
+| `WS /auth/ws/authenticate` | Passkey authentication | Returns a session token |
+| `WS /auth/ws/register` | Register a new credential | Adding another passkey to current user or via reset token |
+| `WS /auth/ws/remote-auth/request` | Start a cross-device login/registration request | Used from unauthenticated client |

+
+### Auth host mode (`--auth-host`)
+
+#### On the auth host:
+- The Web UI is served at site root (e.g. admin UI at `/admin/`), and the `/auth/...` equivalents (e.g. `/auth/admin/`) redirect to the root paths.
+- All of the API stays under `/auth/api/*`
+- Auth WebSockets remain at `/auth/ws/*` but take connections from other hosts to issue sessions for each of those.
+
+#### On non-auth hosts:
+- `/auth/` shows only minimal profile and allows logging out of the current site
+- `/auth/api/*` is served normally.
+- `/auth/api/user/*`, `/auth/api/admin/*`, and `/auth/ws/*` don't exist.

+# Paskia Caddy Configuration
+
+[Caddy](https://caddyserver.com/) is a modern web server that makes setting up web services easy. We provide a few Caddy snippets that make the configuration even easier, although the `forward_auth` directive of Caddy can be used directly as well. Place the [auth folder](../caddy/auth) with the snippets `require` and `setup` where your config file is (e.g. `/etc/caddy/auth`)
+
+What these snippets do
+- `setup`: Mount the auth UI at `/auth/` proxying to `:4401`
+- `require`: Use `/auth/api/forward` for access control
+- Render a login page or a permission denied page if needed (without changing URL)
+
+Your backend may not use authentication at all, or it can make use of the user information passed via `Remote-*` headers by the authentication system, see [trusted headers](Headers.md) for details.
+
+We assume the normal unprotected **Caddyfile** for your site looks like this:
+
+```caddyfile
+app.example.com {
+    @public path /.well-known/* /favicon.ico
+    handle @public {
+        root * /var/www/
+        file_server
+    }
+
+    handle {
+        reverse_proxy :3000  # Your app backend
+    }
+}
+```
+
+Note: We use the `handle @name` approach rather than `handle_path` to keep the path unaltered. Unlike bare directives, these blocks will be tried in sequence and each can contain what you'd typically put in your site definition (by default `reverse_proxy` takes precedence and nothing reaches the static files).
+
+We will adapt from this to protect your app.
+
+### Protect your site (auth/setup, auth/require)
+
+```caddyfile
+app.example.com {
+    import auth/setup
+
+    @public path /.well-known/* /favicon.ico
+    handle @public {
+        root * /var/www/
+        file_server
+    }
+
+    @reports path /reports
+    handle @reports {
+        import auth/require perm=myapp:reports
+        reverse_proxy :3000
+    }
+
+    handle {
+        import auth/require max-age=12h
+        reverse_proxy :3000
+    }
+}
+```
+
+The above setup allows unauthenticated access to certain files, then implements two different access controls for your backend app depending on which path is accessed. Note that the perm and max-age options may be combined, e.g. `perm=myapp:admin&max-age=5min` on a very sensitive endpoint. This will require additional authentication if the passkey hasn't been used in the last 5 minutes (automatic session renewals don't affect this). Use `""` if you only want the user to be authenticated with no time or perm requirements.
+
+### Dedicated Authentication Site
+
+When you setup a separate subdomain for the authentication site, just add to your config another section for the auth host:
+
+```caddyfile
+auth.example.com {
+    reverse_proxy :4401
+}
+```
+
+Remember to specify `paskia serve --auth-host auth.example.com` to restrict the authentication services to this domain.
+
+Note that we still reserve `/auth/` on each site for logout page and any APIs your application may require, while full user profile and global options are only available on the auth host.
+
+Paskia does not require CORS configuration, but it can access the authentication and registration of auth host WS API from the other sites as WebSockets don't require any CORS.
+
+### Override the paskia backend address (AUTH_UPSTREAM)
+
+By default, the auth service is contacted at localhost port 4401. You can point Caddy to a different address by setting the `AUTH_UPSTREAM` environment variable for Caddy.
+
+If unset, the snippets use `:4401` by default.

+# Paskia Trusted Headers for Backend Apps
+
+| HTTP Header | Meaning | Example |
+|---|---|---|
+| `Remote-User` | Authenticated user UUID | **01c03276-b8f0-**… (string) |
+| `Remote-Name` | User display name | **John Doe** |
+| `Remote-Org` | Organization UUID | Identifier for user's org (string) |
+| `Remote-Org-Name` | Organization display name | **The Company Ltd.** |
+| `Remote-Role` | Role UUID | Identifier for user's role (string) |
+| `Remote-Role-Name` | Role display name | **Employee** |
+| `Remote-Groups` | Permissions the user has, comma separated | **auth:admin,yourapp:reports** |
+| `Remote-Session-Expires` | Session expiry timestamp (ISO 8601 UTC) | **2030-12-31T23:59:59Z** |
+| `Remote-Credential` | Credential UUID | Identifier for the sign-in passkey (string) |
+
+Similar headers are also used by other authentication systems like [Authelia](https://www.authelia.com/integration/trusted-header-sso/introduction/) to signal the backend application information about the signed in user.
+
+When a request is allowed, the auth service adds these headers by the forward-auth mechanism before proxying to your app as **request headers**. Your app can use them for user context to show on UI, or for its own authentication needs (e.g. prevent different orgs messing up with each other's data, logging which user performed an action).
+
+Only the UUID values should be used for identification needs, because they never change, even when things are renamed (display names change), and are never reused (created on authentication server). They are UUIDv7 so you can also extract the creation timestamp from them.
+
+Any `Remote-*` headers from clients are stripped by our [Caddy configuration](Caddy.md) to avoid dealing with any fake headers.
+
+Note: the headers are intended primarily for the backend, while either frontend or backend (passing the session cookie) can request `/auth/api/user-info` for more complete information, and that is the recommended way to do it in the frontend. See [integration](Integration.md) for more.

+# Integrating Paskia with your App
+
+This guide covers frontend and backend integration with Paskia. For Caddy forward-auth setup, see [Caddy configuration](Caddy.md).
+
+## Frontend Integration
+
+### Using the paskia-js Module
+
+The [paskia](https://www.npmjs.com/package/paskia) JavaScript module provides utilities for API calls, session validation, and authentication overlays. Works with any framework or vanilla JS.
+
+```html
+<script type="module">
+  import { apiJson, apiFetch, SessionValidator } from 'https://cdn.jsdelivr.net/npm/paskia@latest/dist/paskia.js'
+</script>
+```
+
+Or install to your project:
+
+```sh
+npm install paskia
+```
+
+### API Fetch with Automatic Auth
+
+Use `apiJson` or `apiFetch` for API calls. When a 401/403 response includes an auth URL, the authentication dialog appears automatically, then the request retries. The JSON variant is purely for convenience, doing JSON headers and conversions for you.
+
+```js
+import { apiJson, apiFetch, AuthCancelledError } from 'paskia'
+
+// JSON API call (sets Content-Type, parses response)
+try {
+  const data = await apiJson('/api/endpoint', { method: 'POST', body: { key: 'value' } })
+} catch (e) {
+  if (e instanceof AuthCancelledError) {
+    // User cancelled auth dialog
+  }
+}
+
+// Raw fetch with auth handling (returns Response object)
+const response = await apiFetch('/api/endpoint')
+```
+
+For requests that shouldn't trigger auth dialogs, use standard `fetch` or our `fetchJson`.
+
+### Session Validation Polling
+
+Keep sessions alive and detect when the user logs out or switches accounts:
+
+```js
+import { SessionValidator } from 'paskia'
+
+const validator = new SessionValidator(
+  () => currentUser?.uuid,              // getter for current user ID
+  (error) => handleSessionLost(error)   // callback when session is lost or user changes
+)
+
+validator.start()  // start polling (pauses on idle)
+validator.stop()   // stop polling
+```
+
+The validator calls `/auth/api/validate` periodically to:
+- Renew the session cookie (24h lifetime)
+- Detect if the user logged out or switched accounts
+- Pause polling when the page is idle, allowing sessions to expire when not used
+
+### Manual Auth Flow
+
+If you need custom control, handle 401/403 responses manually:
+
+```js
+import { showAuthIframe, AuthCancelledError } from 'paskia'
+
+const response = await fetch('/api/protected')
+if (response.status === 401 || response.status === 403) {
+  const data = await response.json()
+  if (data.auth?.iframe) {
+    try {
+      await showAuthIframe(data.auth.iframe)
+      // Retry the original request
+    } catch (e) {
+      if (e instanceof AuthCancelledError) {
+        // User clicked Back
+      }
+    }
+  }
+}
+```
+
+### User Info and Profile
+
+Get current user details:
+
+```js
+const user = await apiJson('/auth/api/user-info', { method: 'POST' })
+// Returns: { uuid, display_name, credentials, sessions, permissions, ... }
+```
+
+Or link to the built-in profile page: `/auth/`
+
+## Backend Integration
+
+### Using Forward-Auth Headers
+
+When using Caddy forward-auth, your backend receives `Remote-*` headers on authenticated requests. See [Headers](Headers.md) for the full list.
+
+```python
+# Example: Python/FastAPI
+@app.get("/api/data")
+def get_data(request: Request):
+    user_id = request.headers.get("Remote-User")
+    org_id = request.headers.get("Remote-Org")
+    permissions = request.headers.get("Remote-Groups", "").split(",")
+    # ...
+```
+
+### Direct Validation from Backend
+
+Your backend can validate sessions directly by calling Paskia's validate endpoint:
+
+```python
+import httpx
+
+async def validate_session(request) -> dict:
+    """Validate a session cookie and check permissions."""
+    authcookie = request.get("__Host-paskia")
+    response = await httpx.post(
+        "http://localhost:4401/auth/api/validate?perm=myapp:login+myapp:api",
+        headers={
+            "Host": request.headers["host"]
+            "X-Forwarded-For": request.client.host,
+            "Cookie": f"__Host-paskia={}",
+        },
+    )
+    if response.status_code != 200:
+        return response.json()  # Return to client
+    # User authenticated... We are good to go!
+    ctx = response.json()  # User and session information
+```
+
+This is useful for:
+- WebSocket connections where headers aren't available after handshake
+- Background jobs that need to verify a stored session
+- APIs not behind forward-auth (auth/restrict)
+
+### Validate Endpoint Parameters
+
+`POST /auth/api/validate` accepts query parameters:
+
+| Parameter | Description |
+|-----------|-------------|
+| `perm=scope:name` | Require this permission (repeatable) |
+| `max_age=5min` | Require recent passkey use |
+
+Returns 200 with user info on success, 401/403 on failure.
+
+## Proxying /auth/ to Paskia
+
+Your app server needs to proxy `/auth/` paths to Paskia. This can be done by your application but is much easier done by Caddy or Nginx.
+
+### Caddy
+
+This handles both HTTP and WebSocket connections. Caddy's `reverse_proxy` handles HTTP and WebSocket transparently. This is essentially what our Caddy [auth/setup](../caddy/auth/setup) snippet does: `reverse_proxy :4401`.
+
+```caddyfile
+app.example.com {
+    import auth/setup
+    # ... your routes in handle blocks
+}
+```
+
+### Nginx
+
+Certain headers need to be configured for correct host and WS support:
+
+```nginx
+location /auth/ {
+    proxy_pass http://localhost:4401;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection "upgrade";
+    proxy_set_header Host $host;
+}
+```
+
+### Node.js / Express
+
+Using `http-proxy-middleware`:
+
+```js
+import { createProxyMiddleware } from 'http-proxy-middleware'
+
+app.use('/auth', createProxyMiddleware({ target: 'http://localhost:4401', ws: true, changeOrigin: false }))
+```
+
+### Python / FastAPI
+
+You will need to process and handle `/auth/` for HTTP requests and `/auth/ws/` for WebSockets manually, which is beyond the scope of this documentation.
+
+We highly recommend Caddy instead as the simpler and more production-worthy solution that Just Works.

+
+JavaScript utilities for [Paskia authentication system](https://git.zi.fi/leovasanko/paskia) integration into web apps.
+
+## Installation
+
+### NPM
+
+No framework dependencies. Works with any framework (Vue, React, Svelte, etc.) or vanilla JS. Typescript typing included.
+
+```sh
+npm install paskia
+```
+
+```js
+import { ... } from 'paskia'
+```
+
+### Plain JavaScript
+
+Fetch the module directly from a CDN, or [download](https://cdn.jsdelivr.net/npm/paskia@latest/dist/paskia.js) first and host yourself. No Node needed.
+
+```html
+<script type="module">
+  import { ... } from 'https://cdn.jsdelivr.net/npm/paskia@latest/dist/paskia.js'
+</script>
+```
+
+## Features
+
+### Session Validation
+
+Refresh session and track its validity with automatic polling. Pauses on lack of user activity to avoid useless traffic and to allow session expiry even when the page is left open but idle. This monitors that the same account stays logged in but doesn't do any permission checks.
+
+```js
+import { SessionValidator } from 'paskia'
+
+const validator = new SessionValidator(
+  () => currentUser?.uuid,  // getter for current user ID that we track
+  (error) => handleSessionLost(error)  // callback when session is lost
+)
+
+validator.start()  // call at your app startup/login
+validator.stop()   // stop the system (optional)
+```
+
+### API Fetch Utilities
+
+Enhanced fetch functions with automatic error handling and authentication retry:
+
+```js
+import { apiJson, apiFetch } from 'paskia'
+
+// JSON API calls with automatic auth handling
+const data = await apiJson('/api/endpoint', { method: 'POST', body: { key: 'value' } })
+
+// Raw fetch with auth handling
+const response = await apiFetch('/api/endpoint')
+```
+
+When a 401/403 response includes an auth iframe URL, the request automatically pauses, displays the authentication UI, and retries upon success. In case this is not needed, use standard `fetch` or our `fetchJson`.
+
+The JSON variants set headers automatically, with body and response in JSON.
+
+### Authentication Overlay
+
+Normally you use apiJson/apiFetch and they handle this automatically. If you need to wire it yourself, on a 401/403 response that includes `auth.iframe`, call `showAuthIframe(...)` and then retry the original request.
+
+The backend returns 401/403 responses with the correct URL for proper user feedback. Alternatively you may use `/auth/restricted/#mode=login`, `mode=reauth` or `mode=forbidden` to trigger the UX flow you need.
+
+```js
+import { showAuthIframe, AuthCancelledError } from 'paskia'
+
+const response = await fetch('/api/protected')
+if (response.status === 401 || response.status === 403) {
+  const data = await response.json()
+  if (data.auth?.iframe) {
+    await showAuthIframe(data.auth.iframe)  // Raises AuthCancelledError if the user cancels
+  }
+}
+```
+
+This resolves after the user authenticates (possibly with another account than previously), and you should usually retry the original API request. Note that successful authentication doesn't guarantee that the user still has rights to what originally failed.
+
+### Shared Blur Backdrop
+
+The authentication dialog displays with a blur backdrop (z-index 1099). The auth iframe uses z-index 9999. Your app dialogs should use z-index 1100–9998 to appear above the backdrop but below authentication.
+
+The backdrop is also reusable/refcounted, so you can keep consistent visuals for your own dialogs:
+
+```js
+import { holdGlobalBackdrop, releaseGlobalBackdrop } from 'paskia'
+
+holdGlobalBackdrop()
+try {
+  await your.own.dialog()
+} finally {
+  releaseGlobalBackdrop()
+}
+```
+
+The backdrop only disappears after all holders have released it.
+
+## Error Handling
+
+### AuthCancelledError (apiFetch, apiJson, showAuthIframe)
+
+If the user clicks Back in the authentication dialog, refusing to authenticate, `AuthCancelledError` is risen (as a response to postMessage from the iframe). The dialog closes as expected and it is up to the app how to continue from there.
+
+- Do nothing if the app can continue despite the failed operation (no UI notification needed)
+- Display a simple Access Denied page with suggestion/button to reload the page to try again
+
+Do not retry automatically.
+
+### UI feedback
+
+A set of small utilities are available for determining whether the user needs a notification and to format the error message.
+
+```js
+import { getUserFriendlyErrorMessage, shouldShowErrorToast } from 'paskia'
+
+try {
+  await apiJson('/api/action')
+} catch (e) {
+  if (shouldShowErrorToast(e)) {
+    your.message.display(getUserFriendlyErrorMessage(e))
+  }
+}
+```
