Confirm support
Ensure the OS and browser support passkeys/WebAuthn and that screen lock/biometrics are enabled.
Check account and sync
Verify passkeys are saved to the correct account (platform sync) and that you are signed into the right profile.
Validate origin/domain
Passkeys are bound to the site origin; confirm you are using the same domain and HTTPS.
Recovery and fallback
Keep backup authenticators and recovery options; remove stale passkeys and re-register if needed.
