Login Concept (Rebound)

Well, the following concept has been chasing me for a while. So, I decided to bring it to life.

Usernames and passwords have always been relying on text inputs until Apple came up with its unique face/fingerprint ID login methods as alternatives to those traditional ways.
In this rough prototype, I imagined it could be faster and more secure (looking for security experts' feedback on this) if we used our fingerprints/faces as identifiers to our usernames and some sort of those login patterns as alternatives to passwords.

P.S. This prototype only covers the success states of a login process. Cases that were considered but not implemented are as follows:
- Invalid fingerprint ID
- Login with another fingerprint (it may happen that a user may have more than one account in an app/service)
- Wrong pass pattern
- Trigger to log in or delete the entered pattern and start over (The current trigger is based on a few seconds delay after the last tap)
- Reset pass pattern

What do you think the pros & cons of such a concept would be?
