+# Forward auth
+
+You can use [forward-auth](https://doc.traefik.io/traefik/middlewares/http/forwardauth/) mechanism to log into Jellyseer.
+
+This works by passing the authenticated user e-mail in `X-Forwarded-User` header by the auth server, therefore enabling single-sign-on (SSO) login.
+
+> The user has to exist, it will not be created automatically.
+
+## Example with Goauthentik and Traefik
+
+This example assumes that you have already configured an `application` and `provider` for Jellyseer in Authentik, and added the `provider` to the `outpost`.
+
+We now have to create a scope mapping that will pass the `X-Forwarded-User` header containing user e-mail to Jellyseerr application.
+
+### Create scope mapping
+
+In Authentik go to `Customization > Propperty Mappings` and create `Scope Mapping`:
+
+* Name: `jellyseerr-forwardauth`
+* Scope: `ak_proxy`
+* Expression:
+
+```py
+return {
+    "ak_proxy": {
+        "user_attributes": {
+            "additionalHeaders": {
+              "X-Forwarded-User": request.user.email
+            }
+        }
+    }
+}
+```
+
+### Add the scope mapping to provider scopes
+
+In authentik go to `Applications > Providers`, edit your `jellyseer` provider:
+
+* Under `Advanced protocol settings` - `Available scopes` select the `jellyseerr-forwardauth` scope that was created in the previous step and add it to the `Selected scopes` list
+* Save the changes by clicking the `Update` button
+
+### Create the forward-auth middleware in Traefik
+
+Now you have to define the forward-auth middleware in Traefik and attach it to the `jellyseerr` router. Authentik also requires to set up login page routing so it could redirect properly to Authentik.
+
+```yml
+    labels:
+      - traefik.enable=true
+
+      # Forward auth middleware
+      - traefik.http.middlewares.auth-authentik.forwardauth.address=http://authentik-server:9000/outpost.goauthentik.io/auth/jellyseerr
+      - traefik.http.middlewares.auth-authentik.forwardauth.trustForwardHeader=true
+      - traefik.http.middlewares.auth-authentik.forwardauth.authResponseHeaders=X-Forwarded-User
+
+      # Router for jellyseerr
+      - traefik.http.routers.jellyseerr.rule=Host(`jellyseerr.domain.com`)
+      - traefik.http.routers.jellyseerr.entrypoints=websecure

+      - traefik.http.routers.jellyseerr.service=jellyseerr
+
+      # Router for login pages
+      - traefik.http.routers.jellyseerr-auth.rule=Host(`jellyseerr.domain.co`) && PathPrefix(`/outpost.goauthentik.io/`)
+      - traefik.http.routers.jellyseerr-auth.entrypoints=websecure
+      # Service - reference the authentik outpost service name
+      - traefik.http.routers.jellyseerr-auth.service=authentik@docker
