It isn't a username or password, it's another factor, similar to how we identify people that we know.
It's not perfect, which is why we have policies for accessing things. It's almost certainly a better security mechanism than a password.

For what it's worth, I would say that Face ID isn't quite a username either. Once known, anyone can reproduce a username. I can't easily recreate your face even if I know you well. That would require an extra set of skills/equipment. The same argument goes for Touch ID.
