Passkeys can reduce password use, but account binding and server validation still need correct implementation. Credential Manager supports the platform experience.
Evaluation approach
Bind registration to the right user and validate challenges server-side. A successful interface response alone is not authority.
Application example
Define account selection, recovery and new-key enrollment when users move between devices.
Limits and considerations
Passkeys do not prevent application tampering or repair API authorization defects.
Which account does enrollment change?
Adding a passkey changes account security settings. Appropriate reauthentication may be needed beyond an active session, and notifying the user of the change may be useful.
Checks and decisions
- Validate challenges
- Bind accounts
- Test recovery
