I’m aware of two others, already mentioned emergency sheets and backups.
Both fall under the “passwordless authentication” umbrella. However they are two totally separate technologies. Face-ID leverages pattern matching to perform local authentication. Passkeys leverage public-key encryption to federate logins.
If you have only partial access to your vault, the first goal ought to be immediately creating a backup so that the situation can not worsen as you go making changes, such as resetting your creds.
