DocumentedSession Recovery Without Blind Trust
I worked on session-recovery controls that made identity checks, step-up decisions and failure states explicit instead of weakening authentication during recovery.
What I built
- I mapped recovery-state transitions, implemented step-up checks at critical boundaries, and made rejection and fallback behavior explicit when identity evidence was insufficient.
Experiments & checks
- Test recovery transitions, expired attempts, and repeated requests.
- Check that support and fallback flows preserve authorization boundaries.
- Capture explicit reasons for step-up, denial, and recovery completion.
Notes & limitations
Account recovery introduced different assurance levels than normal sign-in. I needed to stop fallback paths from becoming easier routes around authentication.
Legacy flows could not be fully rewritten during active roadmap delivery, so changes had to be incremental and auditable.
I brought step-up, rejection and fallback decisions into one traceable recovery state model, making the weaker paths easier to inspect and test without weakening the primary authentication boundary.
