Troubleshooting Guide
Recover from an invalid or stale passkey
This error usually means the account still expects a passkey, but the credential on this device is stale, missing, or no longer matches the current login context.
Quick fixes
- Use one fallback sign-in with password, recovery code, or secondary factor.
- Remove the stale passkey only from the affected account entry, not every device.
- Create a fresh passkey on the device you will actually keep using.
- Verify the new passkey works before removing any older backup factor.
What this error usually means
The passkey often was deleted, replaced, or stored in another device profile while the account still points to an older credential record.
It can also appear after device replacement, account cleanup, or browser profile resets where the server and your local authenticator stop matching.
Safe cleanup without causing more damage
Do not wipe every passkey entry at once. First regain access with a fallback method, then remove only the stale credential tied to the failing device or profile.
This keeps working passkeys on other devices intact while you rebuild access on the current one.
How to rebuild a stable passkey setup
After creating a fresh passkey, test it from a new session immediately. Then register a second passkey on another trusted device or hardware key.
That extra redundancy prevents the same error from becoming a lockout the next time you switch devices.
