I think you're getting downvoted because many people don't understand exactly what you mean by 2FA, and especially, for what purpose.
You could try to clarify that, but let me see if I get this right: You'd like to use 2FA as a more secure way to access your phone, having the phone require 2 factors to unlock it; not as a way to use your phone as one of the "two factors" for some other 3rd party account, right?
Basically, you'd like a phone to support an authentication method requiring 2 factor to unlock the phone itself, for example both a PIN and fingerpring, or passphrase and face recognition, is that right? As in, one needs both factors, not one or the others. If so, yeah, I guess that could be pretty useful for the very security conscious among us.
You are correct. I was thinking about how to set a passphrase on my phone.
In a scenario where one is unconscious, fingerprint or facial recognition are poor protection. Add a passphrase or swipe to a physical identity methods and you are protected.
Not certain, but I think this also could help protect from virtual attacks because even if they get your passphrase they also need a physical identity method.
Now that I think about it, there is a problem: fingerprint & face ID are not 100% correct all the time, so they'd rather have false negatives than false positives, i.e. they'd rather deny access to someone who is authorized, rather than grant access to someone who is not. This is normally not a problem, cause if for whatever reason the biometric method doesn't work (e.g. wet fingers, wearing gloves, wearing full face mask, etc) then you always have the PIN/passphrase ... but with your 2FA idea this wouldn't work anymore.
That's interesting. I have never really used the biometric keys so I'm not familiar with that.
So set up another backup password for situations where biometric keys fail. Then the 2 passes that you type unlock the phone.
