The passkey you presented is not registered on this account.
| HTTP status | 400 |
type | invalid_request |
code | passkey_unknown_credential |
| Default message | This passkey is not registered. |
When this happens
The credential your authenticator offered is not on file. This usually means the passkey was created for a different account, was removed from your account, or you are signing in to the wrong environment.
How to fix it
Try a different passkey, or use account recovery to register a new one. If you still have access through Google or GitHub, sign in that way and add a fresh passkey from settings.
