Thinking about it, I probably wouldn't remember to change my fingerprints to the new ones with all the services I use, I'd probably have to carry my "legacy fingerprints" wherever I go for some time to avoid a lockout.
kind of but others are hard as well... most people don't change their name, date of birth or even email address when they are leaked.
These aren't really "credentials" in that they're not secret the way your iris/retina pattern, fingerprint pattern, password, pin, secret key, or security token are.
Your name, DoB, and email address are identifiers, yes, but aren't really authenticators - they're more like a username, not a password.
