While some security experts quibble over the terms verification and authentication, for our purposes the differences are irrelevant. The real question is, are we actually using two factors or just one disguised as two.
As you might imagine, this is where things get a little tricky. This is the easiest factor to understand: In bitcoin, we use cryptographic key pairs, which are also a knowledge-based proof. Now you need to add you need one of the other factors. Your phone number is not something you own. Phone numbers belong to service providers.
They are fully controlled by the network providers. Sure, you can choose a new network provider, but control of the account always remains with a phone company within their service-provider network. If you do own your phone, you can use it as a second factor easily. In , I had an iPhone with a fingerprint scanner. This is going to be so easy!

This makes them far less desirable, even as a second factor. Biometric factors are unchangeable. Importantly, unlike passwords, biometric factors are unchangeable. Once a thief has your biometric data, it can be used anywhere.
You cannot change your fingerprint or facial structure without significant pain and cost. If we lived in a world where credentials were never stolen or lost, maybe biometrics would be a good choice.
