Reactivate Duo Mobile on Phone or Tablet


Duo Two-Factor Authentication


How do I reactivate Duo? (Usually needed because you replaced your phone with a new model but kept the same phone number or are not getting Duo pushes anymore.)


  1. Go to
  2. Login with your uniqname and password (if prompted)
  3. Go to "Two-Factor (Duo)" > "Manage Duo Devices"
  4. Go through the Duo prompt (you may need to choose phone call or use an alternate Duo method)
  5. For the phone/tablet to be reactivated, click "Device Options"
  6. Click "Reactivate Duo Mobile"
  7. Follow the prompts
    1. Install App on device if not already installed
    2. Open the app and click the + sign in the upper right
    3. Scan the QR Code
    4. Click continue
  8. 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 allow you to sign in and update your own settings. Because this requires identity verification, please contact the Service Center via phone at 734-764-HELP (4357) and select option 1.
