Thanks for the instructions, I like the fact that Google Authenticator doesn't need to contact their servers (or at least that's how I understand it). Sounds like you could preserve the use of SSH public key authentication by using Google Authenticator in combination with a ForceCommand; I'll have to look in to that. Anyone set up Google Authenticator to only challenge me on a host every N minutes or something like that? I.e., first login requires two-factor auth, subsequent logins don't for at least 30 minutes? Seems like it'd be irritating to keep popping my phone out every time I connect to a remote server.
