# passkey_unknown_credential (/api/errors/passkey_unknown_credential)



<ErrorMeta code="passkey_unknown_credential" />

## When this happens [#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 [#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.
