Two-Factor Authentication: How to generate a Two-Factor Passcode online

What is the purpose of a two-factor passcode?

Consider the scenario where you have enrolled in two-factor authentication and registered your smartphone as your second factor device. You come to the office ready to go to work, but then you realize you left your smartphone at home. In that scenario, you can generate a passcode that you can use for up to 24 hours in lieu of your second factor device. A passcode can also come in handy when you buy a new smartphone to replace your old one. Since your old phone is no longer operational, you will need a passcode so that you can log in to duo.msstate.edu to add your new mobile device and remove your old device.
