Using Duo multi-factor authentication

When you're prompted to verify your identity using Duo Mobile, you confirm your identity using either Send Duo Push or Duo Mobile passcode. 

By default, Duo Mobile will send a Push notification to its assigned device. Once confirmed, you may opt to remember your authentication in this browser on this device/computer by checking the Remember me for 30 days checkbox.


For more information on this feature, see How "Remember me" works in Duo multi-factor authentication.

If you do not have Duo Mobile Push configured, or you would like to select a different option, click Other options to view the other available methods of authentication.

Enter Duo passcode

Click Use Duo Mobile passcode to open a text field.
