For 2FA I like how Microsoft does it. You have an app on your phone. When they need to authorize you, they push to the all and it automatically pops up with approve and decline buttons. You verify the code is the same on the phone and screen and hit approve. It's an easier workflow than having to open Google authenticator, find the code, and enter it.
