Now you're ready to use Duo Mobile to log in to your UAH Google account!

Steps for Logging In

The next time you log in, you'll be able to use Duo Mobile as your second step.

  1. Enter your username and password as normal
  2. Google may default to a different 2-Step Verification method. To change your 2-Step method, select Try another way. Then, select Get a verification code from the Google Authenticator app.
  3. On your mobile device, open Duo Mobile and tap Show next to your Google account.
  4. Enter the 6-digit code shown here and you're in!

Please note: Google automatically assumes you are using their official Google Authenticator app, which is why you may see phrasing specific to their application. However, this method works just the same for Duo Mobile.
