BattleBit has become my current obsession. Feels just like playing Battlefield 3 back in the day once you get past the Roblox-esque graphics.

Would it be possible to implement multifactor authentication as an optional log-in step? Preferably supporting authenticator app and hardware tokens rather than just SMS as SMS is now considered an insecure authentication method.
