As the access to our global REST-API "Charon" is bound to OAuth2, we use Keycloak inside Quarkus to authenticate and authorize users of our API. It is not possible to perform any un-authenticated requests against this API, so we wanted to make really sure that the authentication/authorization component is absolutely reliable and tested. We found those attributes within Keycloak, so we used it.
