In theory, I guess, but dragging a desktop to my laptop to log in is a bit much. We need a better solution for that.

The CTAP2 protocol has better alternatives, https://github.com/fmeum/WearAuthn is possible because we already can do better. I just hope it'll be implemented at some point (though, realistically, the future is phone-first, despite how much I dislike the implications that carries).
