[OAuth2](https://oauth.net/2/) defines an _access token_ (used when
authenticating a user) and a number of _authentication roles_ that the user
can participate in (see
[this page](https://www.digitalocean.com/community/tutorials/an-introduction-to-oauth-2)
for an introduction to OAuth2 and a description of the roles). You can use the
[Identity user service](identity-user.service.md) to access this information for users, including the current user.
