This is basically self sovereign 2fa. The sort that a company might use if they have an important brand or reputation.

Imagine, you can turn it on and off exactly when you are using it. Plugging something in is gonna be so much less cumbersome than typing in a password and then getting a code and typing that in and then never logging out either. But maybe that is just me.

Love it. Can't wait for people to take it in all the different directions.

Oh, come on. This device is a mini you, and you can carry it in your pocket. Its physical ownership of your account.
