Why it matters
A successful login should not create access that lasts forever. Sessions need server-enforced expiry, device context and revocation when an account, role or organization policy changes.
Enterprise admins may ask which devices remain signed in after an employee leaves. A session list turns an invisible security state into something a customer can inspect and control.
Decisions to make
- Set idle and absolute timeout rules by account and risk level.
- Choose which device and location details are reliable enough to display.
- Define which administrators may terminate another person’s sessions.
- Decide whether role, password, MFA or SSO changes revoke sessions immediately.
- Plan behavior when revocation storage is briefly unavailable.
Build checklist
- Track sessions on the server with issued, last-seen and expiry times.
- Expose a current-session marker and revoke-one or revoke-all controls.
- Enforce revocation on every protected request, not just in the UI.
- Test concurrent sessions, stolen tokens and clock skew.
- Audit remote termination and high-risk session changes.
Common mistakes
- Treating browser closure or cookie deletion as server-side revocation.
- Displaying a session as active after it has expired or been revoked.
- Leaving old sessions valid after a privileged role change.
