The authenticator is given a lot of leeway in how it does authentication. In the Apple platform case, it is "the user authentication on the device which is on the iCloud account and has set up iCloud Keychain".
So on my Mac I can use TouchID. On my phone I use FaceID. Both allow me to fall back to the device password (such as when I have the lid on my Mac closed).
