Answer:

Yes. To understand how it works, see https://images.apple.com/business/docs/FaceID_Security_Guide.pdf


For an overview, see About Face ID advanced technology - Apple Support


Note that both touched and faced also require a passcode. If that passcode is weak and someone has your device, then the alternate unlocking IDs may be moot. If using a device with touchid or faceid it is best to use a complex passphrase and not a simple 4 or 6 digit passcode. Since you don’t end up entering that passphrase often, it is not terribly inconvenient to enter a 8+ character passphrase (made up the same way you would make any password - e.g. with case changes, at least one number and one special character).
