We present novel Two-Factor Authentication (TFA) protocols with improved resistance against online and offline attacks. We show that our TFA protocols can utilize various device-terminal channels, involving PIN entry, QR codes, or wireless communication, and we demonstrate the security, usability and deployability advantages of the resulting TFA schemes over known TFA schemes.
