Setting up Duo on a new device.


Duo two factor authentication is the method of two factor authentication used across the UM campuses to ensure the security of a member of the university's account.


  • Go to
  • Login with your uniqname and password, if prompted.
  • Click Manage Duo Devices
  • Authenticate to Duo, if prompted, (If app push is unavailable, use the phone call or SMS option).
  • For the phone/tablet to be reactivated, click Device Options.
  • Click Reactivate Duo Mobile.
  • Follow the prompts:
    • Install the app on your device if not already installed.
    • Open the app and click the "+" sign in the upper right.
    • Scan the QR code.
    • Click continue.
  • The device should be set up.

If the phone call option isn't working and a backup device wasn't set up, the Service Center can either reactivate Duo mobile on your behalf, or can assign a temporary Duo bypass code to provide to allow you to sign in and update your own settings.

Because this would require identity verification, please contact the UM-Dearborn Servicedesk at (313) 593-4357 and select option 1.
