Duo Mobile app

If you have the Duo App installed on your smartphone, you can open it and obtain the 6-digit code generated within the app, and use this in the Passcode option when prompted for 2FA.

Your smartphone does not need an active cellular or wireless network signal for this to work, so long as the app has been registered to your account.
