Reactivate Duo Mobile on a New Smartphone

Information

These directions will help you reactivate the Duo app if you have a new phone with the same number. These directions will also help you if you simply need to reactivate push notifications for any reason. If your phone number has changed, please call Help Desk Central at (979) 845-8300 or start a chat at help.tamu.edu.

Instructions

When setting up a new phone, we recommend following the instruction below from an incognito or private browser session or from a web browser you do not typically use.  Otherwise, the browser may default to Push authentication (or whatever you have set your default to be) rather than giving you the opportunity to select Call Me as your authentication type. 
 
  1. Go to duo.tamu.edu and log in with your NetID and NetID password.
  2. If the "Check for a Duo Push" screen appears, click Other options
  3. Authenticate by clicking Phone call. 
    • You will need to answer the call and press '3'.
    • If you cannot receive the phone call, you will need to contact Help Desk Central for bypass codes. Please call (979) 845-8300 or visit the Computing Services Complex (CSC), room CS00.
    • If neither of the above options work for you, you can start a chat at help.tamu.edu or email helpdesk@tamu.edu and request a Zoom meeting. Bypass codes cannot be given out over email or chat.
  4. Select Yes, trust browser or No, do not trust browser
  5. Click My Settings & Devices (blue link on the left side of the page).
  6. Authenticate again by clicking Call Me. You should see your phone number listed.
  7. Click Device Options.
  8. Click Reactivate Duo Mobile.
    • If you have never activated push notifications before, it may say "Activate Duo Mobile."
  9. Follow the prompts. Once you scan the QR code and a green check mark appears, you are done!

Duo Push notifications can appear on your Apple watch as long as the iPhone receiving Duo authentications is paired via Bluetooth to the Apple watch. Ensure that the Duo Mobile App is installed and activated for the iPhone.
