Logout Is Not Always Token Deletion

With purely self-contained JWT access tokens, the server may not have a central record that can instantly invalidate a token. Logout therefore requires an explicit strategy.

Possible approaches include short-lived access tokens, refresh-token revocation, token rotation, deny lists for high-risk scenarios, session stores, or opaque tokens with server-side introspection.

Security architecture should consider stolen tokens, password changes, account disablement, administrator revocation, device logout, and credential rotation.
