The problem I see is that I'll be able to share my password, but somebody won't be able to log in. They'd come back and be confused. If I give them the 2 factor, the computer needs to be there, or they need to say it over radio, and even if they say it over radio, it would be a race before it expires. And yes, presumably, they could work with facebook or the NSA for a portal that bypasses 2 factor, but then they don't need my password.
