I want to disagree, but I can't, because you are right. Though perhaps as wearable tech grows(watches and what not), perhaps the keys will exist there also.

I have a newbie question: Can't we embed a hardware key into a phone, and that'd be just as good as a Yubikey? Do we already do this, or is there a reason why we don't?
