 ## 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
+### Step 1: 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
+```sh
+uvx paskia --rp-id=example.com --rp-name="Example Corp"
 ```

-This binds passkeys to the rp-id, allowing them to be used there or on any subdomain of it. The `--rp-name` is the branding shown in UI and registered with passkeys for everything on your domain (rp id). The `--save` option stores these settings in the database, so future runs only need `paskia --rp-id example.com`, of which we will make use of with the systemd config later on.
+This binds passkeys to the rp-id, allowing them to be used there or on any subdomain of it. The `--rp-name` is the branding shown in UI and registered with passkeys for everything on your domain (rp id). On the first run, you'll see a registration link—use it to create your Admin account.

+
+Your backend can validate sessions directly by calling Paskia's validate endpoint [`/auth/api/validate`](api/validate.md). It generally expects client headers proxied as is, while on the URL you can specify exact requirements.
+
+Usually it is sufficient to simply forward the headers the client sent, assuming your proxy already preserved `Host` and set `X-Forwarded-For` (otherwise set them here with original host and IP). `User-Agent` should also be forwarded if available, omitted if not: do not let your backend HTTP client add its own header.
+
+Be sure to REMOVE connection hop-by-hop headers (these will break WebSockets among other things):

+The proxy server follows the 204 response with the original request to protected service, adding those remote headers to original user request, sent to the service. Any error response is sent directly back to client, never connecting to the protected service.
+
+See [Forward-Auth Proxy Guides](../proxy/index.md) for Caddy, Nginx, Traefik, Apache APISIX, Envoy and HAProxy configuration examples. Caddy users can also start from the dedicated [Caddy configuration guide](../proxy/caddy.md).

+## Query parameters
+
+| Parameter | Description |
+|-----------|-------------|
+| perm | Required permissions. See the [perm argument](perm.md). |
+| max_age | Require recent passkey use. See the [max_age argument](max-age.md). |
+
+## Request headers
+
+| Header | Expected value / note | How Paskia uses it |
+|---|---|---|
+| Host | Forwarded directly from the client | Verifying the session's bound host |
+| Cookie | Forwarded directly or just cookie `__Host-paskia` | Session ID |
+| X-Forwarded-Method | The HTTP method, e.g. POST | Logging of original request |
+| X-Forwarded-Uri | Request path and query, e.g. /reports?foo=bar | Logging of original request |
+| Accept | text/html or anything else | Determines whether failures return an HTML page or JSON |
+
+Connection hop-by-hop headers (Connection, Upgrade, Transfer-Encoding, etc.) must not be forwarded.
+
+## Response
+
+### Success (204)
+
+No response body. Only [Remote headers](../Headers.md) are set on the response and your proxy should forward them to the backend request. The headers, not a response body, are the whole point of this endpoint: they are how the authenticated identity reaches the protected service, which can trust them because it is only reachable through the proxy.
+
+### Failure (400 / 401 / 403)
+
+| Status | Meaning |
+|---|---|
+| 400 | Malformed perm argument (see [perm](perm.md#syntax-errors)). The error detail names `/auth/api/forward` as the origin and never echoes query arguments. |
+| 401 | Session missing or expired, or max_age not satisfied — the user needs to (re)authenticate. |
+| 403 | Requested permissions are missing — the forbidden flow allows signing in with another account. |
+
+Failure responses come in two flavors, chosen by the Accept header, because the audience differs:
+
+- A browser asking for a page (Accept includes text/html) gets a full authentication page it can show directly — the proxy simply passes the response through and the user can sign in without any application involvement.
+- Any other request (fetch, img, ...) gets JSON intended for programmatic handling. Besides the error detail, it carries an auth section whose iframe URL points to a ready-made authentication dialog your frontend can embed, so the user can sign in without leaving your app:
+
+```json
+{
+  "detail": "Additional authentication required",
+  "auth": {
+    "mode": "reauth",
+    "iframe": "/auth/restricted/iframe#mode=reauth&theme=dark"
+  }
+}
+```
+
+The mode field:
+- login: no valid session, need to sign in
+- reauth: additional authentication required (using same passkey)
+- forbidden: lacking required permissions
+
+Extra metadata such as the user's theme override may appear as additional fields and iframe fragment parameters.
+
+Note: we provide a JavaScript package [paskia](https://www.npmjs.com/package/paskia) with helpers for the embedding, fetch 401/403 handling, session renewals and more.
+
+## Session renewal
+
+The forward endpoint **does not renew** the session because in the forward-auth mechanism it could not send the client a renewed session cookie. It only validates the current cookie and returns the trusted headers. Use [/auth/api/validate](validate.md) when you need to refresh the session lifetime. Otherwise the user will have to sign in again every 24h even if they are actively using the service.

+# The max_age argument
+
+[API overview](../API.md) · [`/auth/api/validate`](validate.md) · [`/auth/api/forward`](../forward.md)
+
+The max_age argument is used by endpoints that validate sessions to require a recent passkey use. It is supported by:
+
+- [POST /auth/api/validate](validate.md)
+- [GET /auth/api/forward](forward.md)
+
+## What it checks
+
+max_age limits how long ago the user last authenticated with their passkey. It is intended for high-risk actions where you want to be sure the user recently proved possession of their credential, not just that they still have a valid session cookie.
+
+The check compares the elapsed time since the credential was last used against the given limit:
+
+- If the credential has a last_used timestamp, that time is used.
+- Otherwise, the session's validated timestamp is used as a fallback.
+
+If the authentication is older than max_age, the endpoint returns 401 with mode reauth, prompting the user to re-authenticate.
+
+## Time units
+
+max_age accepts a number followed by one of these units:
+
+| Unit | Meaning |
+|---|---|
+| s | seconds |
+| m / min | minutes |
+| h | hours |
+| d | days |
+
+Examples:
+
+```text
+?max_age=30s
+?max_age=5m
+?max_age=5min
+?max_age=1h
+?max_age=1d
+```
+
+An invalid format is logged as a warning but does not cause the request to fail; the requirement is simply ignored in that case.
+
+## Important notes
+
+- Session renewal by /auth/api/validate does **not** count as fresh authentication. The check is based on the credential's last_used time, not on how recently the session cookie was renewed.
+- max_age is independent of perm. You can use either or both at the same time.

+# The perm argument
+
+[API overview](../API.md) · [`/auth/api/validate`](validate.md) · [`/auth/api/forward`](../forward.md)
+
+The perm argument is used by endpoints that validate sessions to require one or more permission scopes. It is supported by:
+
+- [POST /auth/api/validate](validate.md)
+- [GET /auth/api/forward](forward.md)
+
+## Passing the argument
+
+Repeat the query parameter for each required scope:
+
+```text
+?perm=myapp:read&perm=myapp:write
+```
+
+You can also pass multiple scopes in one parameter by separating them with whitespace (a literal space, i.e. `+` or `%20` in the query string):
+
+```text
+?perm=myapp:read%20myapp:write
+```
+
+Both forms produce the same result.
+
+## Semantics
+
+The perm argument uses **AND** semantics between groups: **every** listed scope group must be satisfied by the effective permissions for the request to succeed. If any required group is not satisfied, the endpoint returns 403.
+
+Within a single group, use `|` to list alternatives with **OR** semantics — the group is satisfied when **any one** of the alternatives is present:
+
+```text
+?perm=myapp:read|myapp:write+myapp:login
+```
+
+This requires `myapp:login` **and** (`myapp:read` **or** `myapp:write`). No whitespace is allowed around the `|` operator.
+
+## Syntax errors
+
+Parsing is strict: anything out of spec is rejected with **400 Bad Request** rather than guessed at. This includes:
+
+- Empty values or alternatives (`?perm=`, `?perm=a||b`, `?perm=|a`, `?perm=a|`)
+- Whitespace around `|` (`?perm=a+|+b`)
+- Characters not allowed in scopes other than the operators (space and `|`); scopes match `^[A-Za-z0-9:._~/-]+$` plus the `*` wildcard. In particular a literal `+` in the decoded value (from a `%2B` in the query string) is rejected — use `+` or `%20` to encode a space, never `%2B`.
+
+Extra spaces between groups (leading, trailing, or repeated) are tolerated, since they can easily result from URL formatting and carry no ambiguity — they only ever add required permissions, never remove them. The `|` operator is parsed strictly: `?perm=foo&perm=|bar` is an error, never a way to make `foo` optional.
+
+## Wildcards
+
+Wildcards work like filenames, with `:` and `/` acting as path separators:
+
+- `*` matches any sequence of characters **within a single segment** (it never crosses a `:` or `/`)
+- `**` matches any sequence of characters, **across separators**
+- Part of a segment can be wildcarded, with required text on either or both sides
+
+```text
+?perm=myapp:*
+```
+
+This matches myapp:read and myapp:write, but **not** myapp:read:all — use `myapp:**` for that. Partial wildcards like `myapp:re*` or `myapp:r*d` match myapp:read. The same applies to path-based scopes: `myapp:path:/api/*` matches myapp:path:/api/clients but not myapp:path:/api/v2/clients — use `myapp:path:/api/**` to span path segments.
+
+## Effective permissions
+
+The permissions available to a session are determined as follows:
+
+1. **Role permissions** — the role assigned to the user contains a set of permission UUIDs.
+2. **Org grantable permissions** — only permissions that the user's organization is allowed to grant are effective.
+3. **Domain filtering** — a permission can be restricted to a specific domain via its domain field. If the request's Host header does not match that domain, the permission is excluded.
+
+The result is the set of effective permission scopes used for the perm check. Domain-restricted permissions let you grant a scope only for a specific site or subdomain without making it global.
+
+## Examples
+
+Require a single permission:
+
+```text
+?perm=myapp:login
+```
+
+Require two permissions:
+
+```text
+?perm=myapp:login&perm=myapp:api

+
+Validate a session and renew its lifetime when needed. This endpoint is normally called by the browser/session validator, but backends may also call it directly when not behind a forward-auth proxy.
+
+See also the [API overview](../API.md) and the [integration guide](../Integration.md).
+
+## Query parameters

+| X-Forwarded-For | Real client IP | Recorded in session data instead of the backend/proxy IP; requires FORWARDED_ALLOW_IPS to trust the immediate peer |
+| User-Agent | Forward the original client UA if available; do not let your backend client add its own default | Recorded in session data only when the header is present; omitting it preserves the existing value |

+  }
+}
+```
+
+If the response includes a Set-Cookie header, the session has been renewed (renewed is true) and you should forward that cookie to the client so the browser updates its expiry. Not forwarding it means the session lifetime is not extended, so the user may need to re-authenticate sooner. Renewals are throttled, so frequent calls usually return renewed: false with no Set-Cookie.

+|---|---|
+| 400 | Malformed perm argument (see [perm](perm.md#syntax-errors)). |
+| 401 | Session missing, expired, or max_age not satisfied. The response body includes auth metadata for the login/reauth iframe. |

+# Apache APISIX Forward-Auth
+
+[`/auth/api/forward`](../api/forward.md) · [Proxy guides](index.md)
+
+This guide uses the Apache APISIX [`forward-auth`](https://apisix.apache.org/docs/apisix/plugins/forward-auth/) plugin to ask Paskia whether each request is allowed.
+
+## Overview
+
+APISIX adds the standard `X-Forwarded-*` headers automatically, but we still tell the plugin to forward `Host`, `Cookie`, and `Accept` from the client request. On a `204` response from Paskia we copy the `Remote-*` headers to the backend request.
+
+## Admin API example
+
+```sh
+# Route that proxies /auth/ to Paskia without forward-auth.
+curl "http://127.0.0.1:9180/apisix/admin/routes" -X PUT \
+  -H "X-API-KEY: ${admin_key}" \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "id": "paskia-auth-ui",
+    "uri": "/auth/*",

+      "nodes": { "localhost:4401": 1 },
+      "type": "roundrobin"
+    }
+  }'
+
+# Protected route that uses Paskia forward-auth.
+curl "http://127.0.0.1:9180/apisix/admin/routes" -X PUT \
+  -H "X-API-KEY: ${admin_key}" \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "id": "app-protected",
+    "uri": "/*",
+    "priority": 10,
+    "plugins": {
+      "forward-auth": {
+        "uri": "http://localhost:4401/auth/api/forward?perm=myapp:login",
+        "request_headers": [
+          "Host",
+          "Cookie",
+          "Accept",
+          "X-Forwarded-Method",
+          "X-Forwarded-Uri",
+          "X-Forwarded-Host",
+          "X-Forwarded-Proto",
+          "X-Forwarded-For"
+        ],
+        "upstream_headers": [
+          "Remote-User",
+          "Remote-Name",
+          "Remote-Groups",
+          "Remote-Org",
+          "Remote-Org-Name",
+          "Remote-Role",
+          "Remote-Role-Name",
+          "Remote-Session-Expires",
+          "Remote-Credential"

+      }
+    },
+    "upstream": {
+      "nodes": { "localhost:3000": 1 },
+      "type": "roundrobin"
+    }
+  }'
+```
+
+The `paskia-auth-ui` route has a higher priority (`priority` defaults to the same value for both routes; you can also rely on the more specific `/auth/*` URI matching first). Because it does not use the `forward-auth` plugin, users can reach the login/profile pages without already being authenticated.

+              weight: 1
+```
+
+Apply it with:
+
+```sh
+adc sync -f paskia.yaml
+```
+
+## What APISIX sends to Paskia
+
+APISIX automatically adds these headers to the auth request:
+
+| Header | Value |
+|---|---|
+| `X-Forwarded-Method` | Original HTTP method |
+| `X-Forwarded-Proto` | Request scheme (`http`/`https`) |
+| `X-Forwarded-Host` | Original host |
+| `X-Forwarded-Uri` | Original request URI |
+| `X-Forwarded-For` | Client IP address |
+
+We list them again in `request_headers` to make sure they are not accidentally filtered out when the list is explicit.
+
+## Response headers
+
+`upstream_headers` lists the `Remote-*` headers that APISIX copies from the auth response to the backend request. The plugin does not support a wildcard here, so each header must be named.
+
+If you want Paskia's failure-response headers (such as `Content-Type` or `Set-Cookie`) to reach the client, list them in `client_headers`. For Paskia this is usually not needed; the response body already contains the JSON auth URL or the HTML login page.
+
+## Adjusting requirements
+
+Change the `uri` query string to require different permissions or recent authentication:
+
+```yaml
+uri: http://localhost:4401/auth/api/forward?perm=myapp:login
+uri: http://localhost:4401/auth/api/forward?perm=myapp:admin&max_age=5min
+uri: http://localhost:4401/auth/api/forward
+```
+
+The last form requires only authentication. See [perm argument](../api/perm.md) and [max_age argument](../api/max-age.md).
+
+## Notes
+
+- The auth request is `GET` by default. Since the `forward-auth` plugin does not forward the request body unless `request_method` is set to `POST`, the default `GET` is the right choice for Paskia.
+- Hop-by-hop headers are handled by APISIX when it builds the auth request, so no extra configuration is needed for `Connection`/`Upgrade`.
+- If Paskia is running on a different host, replace `localhost:4401` with the Paskia service address. For a dedicated authentication host (`--auth-host`), route `auth.example.com` to Paskia instead of `/auth/`.

+# Envoy External Authorization (ext_authz)

+
+## Overview
+
+Envoy's `ext_authz` HTTP filter calls an external HTTP service before forwarding a request to the upstream. The filter needs to know which headers from the original request to send to Paskia, and which headers from Paskia's response to add to the upstream request or to the client response.

+
+## Important configuration details
+
+- **`path_override`** — the auth request always goes to `/auth/api/forward?perm=myapp:login`, no matter which path the client requested. The original path is sent in `X-Forwarded-Uri` for Paskia to log.
+- **`authorization_request.allowed_headers`** — Envoy only forwards the headers you explicitly allow. We allow `Host`, `Cookie`, and `Accept`. The `X-Forwarded-*` headers are added via `headers_to_add` so they are based on Envoy's view of the request, not spoofed client values.
+- **`headers_to_add`** — Envoy supports substitution format strings such as `%REQ(:METHOD)%` and `%REQ(:PATH)%`. These set the headers Paskia uses for logging and host validation.
+- **`authorization_response.allowed_upstream_headers`** — `prefix: Remote-` tells Envoy to copy every response header starting with `Remote-` to the upstream request. This also removes any client-supplied `Remote-*` headers, so the backend can trust them.
+- **`authorization_response.allowed_client_headers`** — on a 401/403 response, Envoy forwards only the allowed response headers to the client. Paskia returns HTML or JSON with a `Content-Type` header, so we allow that. (Paskia does not set cookies on the forward-auth response.)
+- **`typed_per_filter_config`** on the `/auth/` route disables `ext_authz` so users can reach the login/profile pages without already being authenticated.
+
+## Per-route requirements
+
+Different routes often need different permissions or `max_age` values. Use `typed_per_filter_config` on each route to override the `http_service.path_override`:
+
+```yaml
+routes:
+  - match:
+      prefix: "/reports"
+    route:
+      cluster: app_backend
+    typed_per_filter_config:
+      envoy.filters.http.ext_authz:
+        "@type": type.googleapis.com/envoy.extensions.filters.http.ext_authz.v3.ExtAuthzPerRoute
+        check_settings:
+          http_service:
+            path_override: "/auth/api/forward?perm=myapp:reports&max_age=5min"
+
+  - match:
+      prefix: "/"
+    route:
+      cluster: app_backend
+    typed_per_filter_config:
+      envoy.filters.http.ext_authz:
+        "@type": type.googleapis.com/envoy.extensions.filters.http.ext_authz.v3.ExtAuthzPerRoute
+        check_settings:
+          http_service:
+            path_override: "/auth/api/forward?perm=myapp:login"
+```
+
+See [perm argument](../api/perm.md) and [max_age argument](../api/max-age.md) for query parameter syntax.
+
+## WebSocket support for `/auth/`
+
+If you use a dedicated authentication host (`--auth-host`), route `auth.example.com` to the Paskia cluster and you do not need the `/auth/` bypass above. Otherwise, make sure the `/auth/` route keeps the `Upgrade` and `Connection` headers so passkey WebSocket endpoints work. The default Envoy router handles `Upgrade` headers when the client requests them.
+
+## Notes
+
+- Envoy's `ext_authz` filter does not send the request body to the auth server by default. For Paskia this is fine.
+- If Paskia is running behind TLS, use `https://` in `server_uri.uri` and configure the cluster's transport socket.
+- The `failure_mode_allow: false` setting means that if Paskia cannot be reached, Envoy will reject the request. In testing you may prefer `true`, but use `false` in production so a failed auth service cannot accidentally allow traffic.

+# HAProxy Forward-Auth
+
+[`/auth/api/forward`](../api/forward.md) · [Proxy guides](index.md)
+
+HAProxy does not have a built-in forward-auth primitive, but the community [`haproxy-auth-request`](https://github.com/TimWolla/haproxy-auth-request) Lua script provides an `auth-intercept` action that works very similarly to Nginx's `auth_request`. It makes an internal HTTP request to Paskia and copies the response headers to the backend request.
+
+## Requirements
+
+- HAProxy 2.2 or newer (2.0+ may work but 2.2+ supports all features shown here).
+- Compiled with `USE_LUA=1`.
+- The [`haproxy-auth-request`](https://github.com/TimWolla/haproxy-auth-request) Lua script loaded.
+- The [`haproxy-lua-http`](https://github.com/haproxytech/haproxy-lua-http) dependency in the Lua path.
+
+## Overview

+    acl is_auth path_beg /auth/
+    use_backend paskia_ui if is_auth
+
+    # 2. Add the headers Paskia logs / expects. These are then copied to the
+    #    auth subrequest by auth-intercept.
+    http-request set-header X-Forwarded-Method %[method]
+    http-request set-header X-Forwarded-Uri %[url]
+
+    # 3. Run the auth check. The parameters are:
+    #    backend       path                                   method
+    #    req-headers   success-headers                        failure-headers
+    #
+    #    - req-headers:   headers copied from client to Paskia.
+    #    - success-headers: headers copied from Paskia response to backend request.
+    #    - failure-headers: headers copied from Paskia response to client response.
+    http-request lua.auth-intercept paskia_auth /auth/api/forward?perm=myapp:login GET Host,Cookie,Accept,X-Forwarded-Method,X-Forwarded-Uri Remote-* *
+
+    # 4. If the subrequest was not successful, deny the request.
+    http-request deny if ! { var(txn.auth_response_successful) -m bool }
+
+    default_backend app_backend
+```
+
+## What the configuration does
+
+1. **Route `/auth/` to Paskia** — users must be able to reach the login/profile UI without already being authenticated. HAProxy will proxy WebSocket upgrade headers automatically for this backend when the client requests them.
+2. **Set `X-Forwarded-Method` and `X-Forwarded-Uri`** — HAProxy adds these headers to the incoming request so the Lua script can copy them to the auth subrequest. `%[method]` returns the HTTP method and `%[url]` returns the path and query string.
+3. **`lua.auth-intercept`** — sends a `GET` request to `/auth/api/forward?perm=myapp:login` on the `paskia_auth` backend. It copies the listed request headers (including the dynamic ones we just set) to the auth subrequest.
+4. **On success (`2xx`)** — copies every response header matching `Remote-*` from Paskia to the backend request. This overrides any client-supplied `Remote-*` headers, so the backend can trust them.
+5. **On failure (`4xx`)** — copies all response headers (`*`) to the client response and uses Paskia's response body, so the browser gets the login HTML or the JSON auth URL.
+6. **Deny if auth failed** — the final `http-request deny` rule is a safety net. In practice, `auth-intercept` with `*` as the failure-headers already terminates the transaction with Paskia's response.
+
+## Backend definition for the auth subrequest
+
+The `paskia_auth` backend can be the same physical server as `paskia_ui`, but using a separate backend is convenient because the Lua script will use the first available server in the backend. The auth subrequest is a plain HTTP request, so no special WebSocket options are needed here.
+
+```haproxy
+backend paskia_auth
+    server paskia 127.0.0.1:4401
+```
+
+## Per-route permissions
+
+You can run different auth checks for different paths by using HAProxy ACLs. Place the more specific rules before the generic one:
+
+```haproxy
+frontend app
+    bind *:80
+
+    acl is_auth path_beg /auth/
+    use_backend paskia_ui if is_auth
+
+    acl is_reports path_beg /reports
+    http-request set-header X-Forwarded-Method %[method] if is_reports
+    http-request set-header X-Forwarded-Uri %[url] if is_reports
+    http-request lua.auth-intercept paskia_auth /auth/api/forward?perm=myapp:reports&max_age=5min GET Host,Cookie,Accept,X-Forwarded-Method,X-Forwarded-Uri Remote-* * if is_reports
+
+    http-request set-header X-Forwarded-Method %[method]
+    http-request set-header X-Forwarded-Uri %[url]
+    http-request lua.auth-intercept paskia_auth /auth/api/forward?perm=myapp:login GET Host,Cookie,Accept,X-Forwarded-Method,X-Forwarded-Uri Remote-* *
+
+    http-request deny if ! { var(txn.auth_response_successful) -m bool }
+    default_backend app_backend
+```
+
+See [perm argument](../api/perm.md) and [max_age argument](../api/max-age.md) for query parameter syntax.
+
+## Notes
+
+- The Lua script strips the request body from the auth subrequest, so Paskia's `/auth/api/forward` will only see the headers.
+- HAProxy variables are limited to alphanumeric characters, dots, and underscores, but the script already normalizes header names for you (e.g. `Remote-User` becomes `req.auth_response_header.remote_user`). The `Remote-*` glob pattern in the success-headers argument handles this automatically.
+- The auth backend must be reachable without TLS. If you need TLS to Paskia, run a local TCP forwarder or use HAProxy's Lua HTTP support directly (not covered by this script).
+- If you use a dedicated authentication host (`--auth-host`), route `auth.example.com` to the Paskia backend and start Paskia with `--auth-host auth.example.com` instead of exposing `/auth/` on every site.

+# Forward-Auth Proxy Guides
+
+[`/auth/api/forward`](../api/forward.md) · [Trusted headers](../Headers.md)
+
+These guides show how to protect a backend application with Paskia using the forward-auth (also called "external authentication") mechanism. The reverse proxy asks Paskia whether a request is allowed before forwarding it to the protected service.
+
+For details about the endpoint the proxy calls, see [`/auth/api/forward`](../api/forward.md). For the headers your backend receives on successful requests, see [Trusted Headers](../Headers.md).
+
+## Available guides
+
+- [Caddy](caddy.md) — fully supported with ready-to-use snippets (`auth/setup` and `auth/require`).
+- [Nginx](nginx.md) — using the `auth_request` module.
+- [Traefik](traefik.md) — using the `ForwardAuth` middleware.
+- [Apache APISIX](apisix.md) — using the `forward-auth` plugin.
+- [Envoy](envoy.md) — using the `ext_authz` HTTP filter.
+- [HAProxy](haproxy.md) — using a Lua auth request.
+
+## Common requirements
+
+No matter which proxy you use, the auth subrequest must:
+
+1. Be sent to `GET /auth/api/forward` on the Paskia backend. By default Paskia listens on `localhost:4401`; set the `AUTH_UPSTREAM` environment variable in our Caddy snippets, or point your proxy at wherever Paskia is running.
+2. Include the query parameters Paskia needs for access control:
+   - `perm` — required permission scope, repeatable (e.g. `perm=myapp:login`). See [perm argument](../api/perm.md).
+   - `max_age` — how recently the user must have authenticated (e.g. `max_age=5min`). See [max_age argument](../api/max-age.md).
+3. Forward these request headers from the original client request:
+   - `Host` — the site the user is visiting.
+   - `Cookie` — the session cookie, normally `__Host-paskia`.
+   - `X-Forwarded-Method` — the original HTTP method (e.g. `GET`, `POST`).
+   - `X-Forwarded-Uri` — the original path and query string (e.g. `/reports?foo=bar`).
+   - `Accept` — decides whether a 401/403 response should be HTML (browser) or JSON (API/fetch).
+4. Strip hop-by-hop headers (`Connection`, `Upgrade`, `Transfer-Encoding`, `Keep-Alive`, `Proxy-Connection`, `TE`) from the auth subrequest. The auth check is a plain HTTP request and must not carry WebSocket/body framing headers.
+5. On a `204 No Content` response, copy the `Remote-*` response headers to the request that is forwarded to the protected backend. The headers are the whole point of the auth check.
+6. On a 401/403 response, send Paskia's response back to the client without contacting the protected backend.
+7. Also proxy the `/auth/` path prefix to Paskia so the login/profile UI, API endpoints, and WebSockets are reachable. Paskia's WebSocket endpoints need `Upgrade` and `Connection` headers passed through for that path.
+
+## Backend usage
+
+After the proxy forwards the request, your backend can read the trusted headers. For example, in Python/FastAPI:
+
+```python
+user_id = request.headers.get("Remote-User")
+org_id = request.headers.get("Remote-Org")
+permissions = request.headers.get("Remote-Groups", "").split(",")
+```
+
+Only trust headers that come from the proxy; never trust `Remote-*` headers that arrive directly from the internet. Your proxy configuration should strip any client-supplied `Remote-*` headers before the auth check.

+# Nginx Forward-Auth

+[`/auth/api/forward`](../api/forward.md) · [Proxy guides](index.md)

+
+## What the configuration does
+
+1. **`/auth/`** is proxied straight to Paskia. The `Upgrade` and `Connection` headers are passed through so WebSocket endpoints such as `/auth/ws/authenticate` work.
+2. **`/`** is protected by `auth_request /auth-internal`. Nginx makes an internal subrequest to that location before proxying the original request to the app.
+3. **`auth_request_set`** captures each `Remote-*` header from the Paskia response. Nginx does not have wildcard capture, so every header must be listed explicitly. The captured values are then attached to the backend request with `proxy_set_header`.
+4. The `proxy_set_header` lines override any `Remote-*` headers the client might have sent, so the backend can trust the headers that come from Paskia.
+5. **`/auth-internal`** is the actual forward-auth call. It must:
+   - point to `/auth/api/forward`,
+   - not forward the request body (`proxy_pass_request_body off;`),
+   - pass `Host`, `Cookie`, `Accept`, `X-Forwarded-Method`, and `X-Forwarded-Uri`,
+   - strip hop-by-hop headers.
+
+## Adjusting requirements
+
+Change the query string on the `proxy_pass` line inside `/auth-internal` to require different permissions or recent authentication:

+proxy_pass http://localhost:4401/auth/api/forward?perm=myapp:admin&max_age=5min;
+proxy_pass http://localhost:4401/auth/api/forward?"";
+```
+
+The last form (`?""`) requires only authentication and no specific permission. See [perm argument](../api/perm.md) and [max_age argument](../api/max-age.md) for details.
+
+## Public paths
+
+To leave some paths unprotected (for example `/.well-known/` or `/static/`), add `location` blocks before the protected `location /` block:
+
+```nginx
+location /.well-known/ {
+    root /var/www;
+}
+
+location /static/ {
+    root /var/www;
+}
+```
+
+## Notes
+
+- Nginx `auth_request` always makes the auth subrequest with the same HTTP method as the original request, but the body is suppressed by the configuration above. Paskia uses the `X-Forwarded-Method` and `X-Forwarded-Uri` headers for logging.
+- The `auth_request_set` variables are empty when the auth request fails, so on 401/403 the backend is never contacted; Nginx returns Paskia's response directly.
+- For HTTPS, add `listen 443 ssl;` and your certificate configuration as usual.

+# Traefik ForwardAuth
+
+[`/auth/api/forward`](../api/forward.md) · [Proxy guides](index.md)
+
+This guide uses Traefik's [ForwardAuth middleware](https://doc.traefik.io/traefik/reference/routing-configuration/http/middlewares/forwardauth/) to ask Paskia whether each request is allowed.
+
+## Overview
+
+A typical dynamic (YAML) configuration looks like this:
+
+```yaml
+http:
+  routers:
+    app:
+      rule: "Host(`app.example.com`)"
+      service: app-backend
+      middlewares:
+        - paskia-auth
+
+    # Route /auth/ straight to Paskia, bypassing the auth middleware.
+    auth:
+      rule: "Host(`app.example.com`) && PathPrefix(`/auth/`)"
+      service: paskia
+      middlewares: []
+
+  middlewares:
+    paskia-auth:
+      forwardAuth:
+        address: "http://localhost:4401/auth/api/forward?perm=myapp:login"
+        # Forward every Remote-* header from the auth response to the backend.
+        authResponseHeadersRegex: "^Remote-"
+        # Explicitly pass the headers Paskia needs. If left empty, all headers
+        # are forwarded; being explicit avoids accidentally leaking hop-by-hop
+        # headers to the auth server.
+        authRequestHeaders:
+          - Host
+          - Cookie
+          - Accept
+          - X-Forwarded-Method
+          - X-Forwarded-Uri
+          - X-Forwarded-Host
+          - X-Forwarded-Proto
+          - X-Forwarded-For
+
+  services:
+    app-backend:
+      loadBalancer:
+        servers:
+          - url: "http://localhost:3000"
+
+    paskia:
+      loadBalancer:
+        servers:
+          - url: "http://localhost:4401"
+```
+
+## What Traefik sends automatically
+
+Traefik's ForwardAuth middleware sends the auth request to the configured `address` and includes the following headers derived from the original request:
+
+| Header | Value |
+|---|---|
+| `X-Forwarded-Method` | Original HTTP method |
+| `X-Forwarded-Proto` | Original protocol (`http`/`https`) |
+| `X-Forwarded-Host` | Original host |
+| `X-Forwarded-Uri` | Original request URI (path and query) |
+| `X-Forwarded-For` | Client IP address |
+
+These are exactly the headers Paskia logs. You should still include them in `authRequestHeaders` if you set that list explicitly, to make sure they are not filtered out.
+
+## Response headers
+
+`authResponseHeadersRegex: "^Remote-"` tells Traefik to copy every response header starting with `Remote-` from Paskia's `204` response and add it to the request that is forwarded to your backend. It also strips any `Remote-*` headers that the client may have sent, so the backend can trust the values.
+
+For stricter control, you can list the headers explicitly instead of using the regex:
+
+```yaml
+authResponseHeaders:
+  - Remote-User
+  - Remote-Name
+  - Remote-Groups
+  - Remote-Org
+  - Remote-Org-Name
+  - Remote-Role
+  - Remote-Role-Name
+  - Remote-Session-Expires
+  - Remote-Credential
+```
+
+## Proxying `/auth/` to Paskia
+
+The `/auth/` router above forwards all authentication UI, API, and WebSocket traffic to Paskia. Because this router does **not** use the `paskia-auth` middleware, users can reach the login page and profile UI without being authenticated first. Traefik handles WebSocket upgrades automatically when the client requests them.
+
+If you are using a dedicated authentication host instead of `/auth/`, create a separate router for `auth.example.com` pointing to the Paskia service and start Paskia with `--auth-host auth.example.com`.
+
+## Adjusting requirements
+
+Change the `address` query string to require different permissions or recent authentication:
+
+```yaml
+address: "http://localhost:4401/auth/api/forward?perm=myapp:login"
+address: "http://localhost:4401/auth/api/forward?perm=myapp:admin&max_age=5min"
+address: "http://localhost:4401/auth/api/forward"
+```
+
+The last form requires only authentication, no specific permission. See [perm argument](../api/perm.md) and [max_age argument](../api/max-age.md).
+
+## Docker labels example
+
+When using Traefik with Docker Compose, you can define the middleware with labels:
+
+```yaml
+labels:
+  - "traefik.enable=true"
+  - "traefik.http.routers.myapp.rule=Host(`app.example.com`)"
+  - "traefik.http.routers.myapp.middlewares=paskia-auth"
+  - "traefik.http.middlewares.paskia-auth.forwardauth.address=http://localhost:4401/auth/api/forward?perm=myapp:login"
+  - "traefik.http.middlewares.paskia-auth.forwardauth.authResponseHeadersRegex=^Remote-"
+  - "traefik.http.middlewares.paskia-auth.forwardauth.authRequestHeaders=Host,Cookie,Accept,X-Forwarded-Method,X-Forwarded-Uri"
+```
+
+## Notes
+
+- By default ForwardAuth sends a request without the original body. If you need to forward the body for logging/validation, set `forwardBody: true` and a sensible `maxBodySize`, but for Paskia this is not required.
+- Paskia does not set cookies on the forward-auth response; it only returns `Remote-*` headers. Use the JavaScript helpers from the [paskia](https://www.npmjs.com/package/paskia) package for session renewal in the frontend.
+- For HTTPS, use `https://` in the `address` and configure TLS options (`tls.insecureSkipVerify: true` only for testing).

 The JSON variants set headers automatically, with body and response in JSON.

+### Timeout Settings
+
+Paskia exports a mutable settings object for defaults used by fetch/auth/session validation timers. Default values shown below.
+
+```js
+import { settings } from 'paskia'
+
+// General fetch timeout used by apiFetch/apiJson/fetchJson when no timeout is passed
+settings.fetch_ms = 10000
+
+// Fetch timeout used by SessionValidator (/auth/api/validate is fast)
+settings.auth_ms = 1000
+
+// SessionValidator polling and idle timers
+settings.poll_ms = 60000
+settings.idle_ms = 300000
+```
+
+You can still override timeout per request:
+
+```js
+await apiJson('/api/upload', { method: 'POST', body: data, timeout: 30000 })
+```
+
 ### 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.

Author	SHA1	Message	Date
LeoVasanko	2456730f70	Check max-age only after checking permissions: if neither is passing, we want a 403 error; simply authenticating again won't fix it so don't bother reauth flow. After forbidden flow e.g. account change we are already good with max-age too.	2026-08-11 00:56:01 +00:00
LeoVasanko	f74bf3ebe6	Require Python 3.14, ruff formatting for simpler typing.	2026-08-11 00:46:45 +00:00
LeoVasanko	79074dd4f1	OR semantics in perm query arg, strict parsing, segment-aware wildcards perm=a\|b+c now means (a or b) and c; repeated perm args remain ANDed. Out-of-spec values (empty alternatives, chars outside the scope charset, stray %2B) are rejected with 400 instead of being silently misparsed; extra spaces between groups are tolerated. Forward endpoint 400/500 details name /auth/api/forward as origin without echoing query args. Wildcards are now filename-like: * stays within a :- or /-separated segment, ** spans segments, partial segments allowed. Slash added to allowed scope characters for path-based permissions.	2026-08-11 00:44:58 +00:00
LeoVasanko	00ef0ae2e7	Update API and proxy docs	2026-08-10 21:35:46 +00:00
LeoVasanko	6f5287e070	Avoid clearing session.user_agent if a validation request lack this header. Backend-initiated session validations may not have the data.	2026-08-10 14:09:42 +00:00
LeoVasanko	051e1bbb41	Replace paskia.db.logging with kanta's built-in logging (kanta 0.7.0) The vendored db/logging module duplicated what kanta now provides: diff formatting, UUID-to-label resolution via logfmt callbacks, unsafe character filtering and value truncation. Censoring of oidc.key material moves into the format_log_uuid logfmt callback in db.lifecycle, taking care to hide only the value, not the 'key' path component itself.	2026-08-09 23:25:16 +00:00
LeoVasanko	4b156b712c	Proper handling of auth site runtime change done via web interface, making the change immediately effective. Kept in origins list that is still also visible on the same dialog, where it can be removed if needed.	2026-08-09 23:00:22 +00:00

LeoVasanko	d31c09084e	Make rpid.paskiadb a folder containing the database and the files in one. Migrates existing old format rpid.paskiadb file to main.db.	2026-05-22 01:22:35 +00:00
LeoVasanko	cc938dd306	Fix a call to loadOrgs when renaming a role, missed in earlier refactoring where we use loadAdminData() for refreshing.	2026-05-22 00:31:06 +00:00

LeoVasanko	42b54cf645	Release 1.4.0	2026-04-29 20:48:12 +00:00
LeoVasanko	232d0e1ae0	Added configurable timeout settings to paskia-js, used in our frontend as well. The default fetch timeout has been changed to 10s from prior 1s, but we maintain 1s for auth endpoints in internal use.	2026-04-29 20:23:38 +00:00

No cookie is read or written, no DB writes. - perm= query arg supported (same wildcard semantics as validate/forward) - Returns valid bool + minimal ctx (user/org/role/permissions) - Permissions are host-scoped via domain filtering, same as session_ctx - 404 if UUID not found; valid=false if perm check fails (no 403) - Add ApiCheckUserResponse struct to apistructs - Add has_all_scopes() helper to permutil for scope-set-based checks	2026-04-26 05:45:59 +00:00
