Session Recovery Without Blind Trust
Making identity recovery paths explicit instead of quietly weakening authentication.

Conceptual design diagram only. It is not a screenshot or claim about a specific production deployment.
The problem
Account recovery paths created weaker guarantees than primary authentication and risked becoming a bypass route.
What I worked on
Mapped state transitions, introduced step-up checks at critical edges, and documented explicit fallback behavior for uncertain signals.
Constraints & tradeoffs
Legacy flows could not be fully rewritten during active roadmap delivery, so changes had to be incremental and auditable.
Outcome
Improved reliability of recovery outcomes and lowered decision ambiguity during abuse and support-driven recovery cases.
Public evidence & artifacts
No source repository or demo has been published for this case study yet.
No verified project screenshots are publicly available yet.
What to validate
Practical checks for evaluating this class of system.
- 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.
