Now this is convent, provided I don't have to access my password safe on a mobile device without a USB port. Does Yubikey have an app or work with Google Authenticator? I know I can use LastPass with Google Authenticator to identify trusted devices. Still not perfect, but perfect security would be too inconvenient for anyone to use.
