Features

The Id Service comes with an app, an API and an admin app.

The app (/) allows users to sign up, login, reset their password and update their account settings.

The API (/api/v1) can check the validity of a session and share some user profile with other services. It also provides endpoints to manage an app and its collaborators, installations, keys, links or permissions.

The admin app (/admin) offers a way to lookup a user and upgrade or revoke their access to the platform. It is also the place where app permissions are managed at a system level.
