 # Paskia
 
+![Login dialog screenshot](https://git.zi.fi/leovasanko/paskia/raw/main/docs/screenshots/login-light.webp)
+
 An easy to install passkey-based authentication service that protects any web application with strong passwordless login.
 
 ## What is Paskia?
 
 - Easy to use fully featured auth&auth system (login and permissions)
-- Organization and role-based access control (optional)
+- Organization and role-based access control
    * Org admins control their users and roles
-   * Master admin can create multiple independent orgs
-   * Master admin makes permissions available for orgs to assign
-- User Profile and Administration by API and web interface.
-under `/auth/` or `auth.example.com`
-- Reset tokens and additional device linking via QR code or codewords.
-- Pure Python, FastAPI, packaged with prebuilt Vue frontend
+   * 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.
+
+## Authenticate to get to your app, or in your app
 
-Two interfaces:
 - API fetch: auth checks and login without leaving your app
 - Forward-auth proxy: protect any unprotected site or service (Caddy, Nginx)
 
 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.
 
-Single Sign-On (SSO): Users register once and authenticate across all applications under your domain name (configured rp-id).
+## 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 [UV](https://docs.astral.sh/uv/getting-started/installation/) and run:
 
 ```fish
-uvx paskia serve --rp-id example.com
+uvx paskia --rp-id example.com
 ```
 
-On the first run it downloads the software and prints a registration link for the Admin.  The server will start up on [localhost:4401](http://localhost:4401) *for authentication required*, serving for `*.example.com`. If you are going to be connecting `localhost` directly, for testing, leave out the rp-id.

 ## Configuration
 
-There is no config file. Pass only the options on CLI:
+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
-paskia serve [options]
+paskia [options]
 ```
 
 | Option | Description | Default |
 |--------|-------------|---------|
-| Listen address | One of *host***:***port* (default all hosts, port 4401) or **unix:***path***/paskia.socket** (Unix socket) | **localhost:4401** |
-| --rp-id *domain* | Main/top domain | **localhost** |
-| --rp-name *"text"* | Name of your company or site | Same as rp-id |
-| --origin *url* | Explicitly list the domain names served | **https://**_rp-id_ |
-| --auth-host *domain* | Dedicated authentication site (e.g., **auth.example.com**) | **Unspecified:** we use **/auth/** on **every** site under rp-id.|
+| -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
+paskia
+```
+
+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.
+
+### Step 2: Production Configuration
+
+For a real deployment, configure Paskia with your domain name (rp-id). This enables SSO setup for that domain and any subdomains.
+
+```fish
+paskia --rp-id example.com --rp-name "Example Corp" --save
+```
+
+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
+
+Install [Caddy](https://caddyserver.com/) and copy the [auth folder](caddy/auth) to `/etc/caddy/auth`. Say your current unprotected Caddyfile looks like this:
+
+```caddyfile
+app.example.com {
+    reverse_proxy :3000
+}
+```
+
+Add Paskia full site protection:
+
+```caddyfile
+app.example.com {
+    import auth/setup
+    handle {
+        import auth/require perm=myapp:login
+        reverse_proxy :3000
+    }
+}
+```
+
+Run `systemctl reload caddy`. Now `app.example.com` requires the `myapp:login` permission. Try accessing it and you'll land on a login dialog.
+
+### Step 4: Assign Permissions via Admin Panel
+
+![Admin panel permissions](https://git.zi.fi/leovasanko/paskia/raw/main/docs/screenshots/master-permissions.webp)
+
+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
+
+Now you have granted yourself the new permission.
+
+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).
+
+### 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
+```
+

 # Integrating Paskia with your App
 
-Protect API routes with forward-auth (see [Caddy configuration](Caddy.md)). Optionally protect your app assets and not just the API.
+This guide covers frontend and backend integration with Paskia. For Caddy forward-auth setup, see [Caddy configuration](Caddy.md).
 
-Catch response status 401/403 in fetch calls to protected endpoints and implement authentication flow in this case. The response is JSON and contains `detail` (an error message describing what is needed) and `auth.iframe` (a URL). Render that URL in an iframe and retry the request after authentication (see below).
+## Frontend Integration
 
-While the app is in (active) use, call `/auth/api/validate` occasionally to keep the session alive (session lifetime is 24h), otherwise the user will have to login every day. Max-age limits are unaffected by this and can be used on endpoints needing to reauthenticate with passkey more frequently.
+### Using the paskia-js Module
 
-Fetch `/auth/api/user-info` to display user/session details, or link to `/auth/` if you prefer using the built-in profile UI and not having to do anything more.
+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.
 
-## Authentication Flow (iframe)
-
-```js
-// Show an authentication dialog
-const iframe = document.createElement('iframe')
-iframe.src = auth.url   // from 401/403 response JSON
-iframe.style.cssText = `
-  position: fixed;
-  inset: 0;
-  width: 100%;
-  height: 100%;
-  border: 0;
-  z-index: 9999;
-  background: transparent;
-  backdrop-filter: blur(0.1rem) brightness(0.7);
-`
-document.body.appendChild(iframe)
-
-// Wait until user is finished with the dialog
-const handler = ev => {
-  if (ev.origin !== location.origin) return
-  iframe.remove()
-  removeEventListener('message', handler)
-  if (ev.data?.type === 'auth-success') retry_original_fetch()
-}
-addEventListener('message', handler)
+```html
+<script type="module">
+  import { apiJson, apiFetch, SessionValidator } from 'https://cdn.jsdelivr.net/npm/paskia@latest/dist/paskia.js'
+</script>
 ```
 
-This describes the frontend flow for handling 401/403 responses from endpoints protected by Paskia forward-auth, without ever exiting your app.
+Or install to your project:
 
-When a protected request fails, the backend returns 401 (needs auth / reauth) or 403 (missing permission). For API requests, the response is JSON that includes an iframe URL. Your app should render that URL in a full-screen iframe overlay, and retry the request after the iframe reports success. If it reports `auth-cancel`, don't try again. The backdrop for the dialog is a stylistic choice, and you can style the background shown with the dialog any way you wish, and consider using CSS file with the iframe rather than inline styles as used in the example.
+```sh
+npm install paskia
+```
 
-Following this flow the user gets authenticated properly and after that your app keeps running as if nothing ever happened.
+### 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))
+  }
+}
+```
