Completely on-topic. Phone-based identification is armed with too much capability inside the black box and limited means for the user to have a clue what is being leaked to whom.
I think there was just a thread here last week about how homeless people get their stuff stolen or lost all the time. 2 Factor keeps people out when you can't reliably Bring Something.
I don't generally want to say that too loud though because some politician will point out that they still have their eyes and fingertips so why can't we use biometrics instead.
99.9% of people have eyes and fingertips. If we’re going to require eye/fingertip authentication to function in society we need to solve for that last 0.1% as well.
