A strong sign-in method loses value if a weaker recovery route permits takeover. Recovery deserves equal attention.
Evaluation approach
Separate lost-device, provider-account-loss and new-device scenarios. Define support evidence requirements.
Application example
Do not replace inaccessible passkeys with easily guessed personal questions that bypass the trust boundary.
Limits and considerations
Stronger recovery must still allow legitimate users to regain access.
Does recovery reopen a weaker method?
Assess effects on every sign-in route. Avoid silently enabling weaker permanent access and bound temporary authority by time and scope.
Checks and decisions
- Separate loss scenarios
- Limit support authority
- Notify recovery events
