Phil, There are four standard session ending controls.
1) Logout 2) Idle session timeout 3) Absolute timeout 4) Forced re-authentication I think these are still important and tend to not get full attention from the OAuth/OIDC crowd. :) But the OAuth 2 standard in particular is a framework - not a standard - which can be implemented many ways, of course.
