OAuth2 Provider

This provider supports both generic OAuth2 as well as OpenID Connect

Scopes can be configured using Scope Mappings, a type of Property Mappings.

Endpoint	URL
Authorization	/application/o/authorize/
Token	/application/o/token/
User Info	/application/o/userinfo/
End Session	/application/o/<application slug>/end-session/
JWKS	/application/o/<application slug>/jwks/
OpenID Configuration	/application/o/<application slug>/.well-known/openid-configuration

GitHub Compatibility

This provider also exposes a GitHub-compatible endpoint. This endpoint can be used by applications, which support authenticating against GitHub Enterprise, but not generic OpenID Connect.

To use any of the GitHub Compatibility scopes, you have to use the GitHub Compatibility Endpoints.

Endpoint	URL
Authorization	/login/oauth/authorize
Token	/login/oauth/access_token
User Info	/user
User Teams Info	/user/teams

To access the user's email address, a scope of user:email is required. To access their groups, read:org is required. Because these scopes are handled by a different endpoint, they are not customisable as a Scope Mapping.

Grant types

authorization_code:

This grant is used to convert an authorization code to a refresh token. The authorization code is retrieved through the Authorization flow, and can only be used once, and expires quickly.

refresh_token:

Refresh tokens can be used as long-lived tokens to access user data, and further renew the refresh token down the road.

client_credentials:

See Machine-to-machine authentication

Scope authorization

By default, every user that has access to an application can request any of the configured scopes. Starting with authentik 2022.4, you can do additional checks for the scope in an expression policy (bound to the application):

# There are additional fields set in the context, use `ak_logger.debug(request.context)` to see them.
if "my-admin-scope" in request.context["oauth_scopes"]:
    return ak_is_group_member(request.user, name="my-admin-group")
return True
