Re: [keycloak-user] When should auth_time claim be updated?

After looking at the code it seems that this is controlled for each authentication attempt with the SSO_AUTH note, the CookieAuthenticator sets it as a client note if cookie authentication succeeds, and the AuthenticationManager checks it and if it's not true updates the auth_time. I can't see anywhere that clears it. I'm not sure how long client notes live, but I assume longer than the current authentication attempt, because once it's set, I can see that it stays true for all my "prompt=login" authentication attempts after that. I changed the CookieAuthenticator to clear the flag first and this seems to fix the problem for me, however, I'm not sure if that's the best approach?

Yes. The claim "auth_time" points to the time of the active authentication. And the re-authentication with SSO cookie is not treated as "active" authentication, so this won't update auth_time. With "prompt=login" you need actively authenticate, so that will update auth_time.
