I'm a Big Fan of the UB Key

I am totally against calling SMS messages 2FA, especially if we're talking about if I can log into your service from my cell phone and you text the code to my cell phone. That's not two factors. That's all just different apps on the same factor. And then the other one is if you're offering 2FA, but you don't support things like my UB key here, I have to use the authenticator app that really grinds my gears. But until you get this physical key from me, I still feel like I have a little bit of control over the situation. How do you feel about the passwordless authentication?
