If you only want to receive phone calls or text messages for 2FA, no action is necessary.  Your new phone will work just like your old phone.

However, if you want to continue using the DUO Mobile app on your new phone, you will need to reactivate your phone by following these steps:

  1. Install the DUO Mobile app on the new phone via the app store or play store depending on the type of device you have
  2. Visit Net ID Center
  3. Login
  4. Authenticate by sending a text message or phone call (DUO push will not work)
  5. Select Manage my 2FA under 2-Factor Authentication
  6. Select + next to the phone number you wish to reactivate
  7. Select Reactivate DUO App
  8. The system will walk you through the steps similar to when you first set up your phone.

If you have already registered a non-campus recovery email address, you can send yourself a temporary passcode.

If you have not yet registered an email address, you must call your university help desk and request a temporary passcode.

Once you have a temporary passcode, you can log into UI Verify and add your new device:

  1. Visit Net ID Center
  2. You will need to authenticate using the temporary pass code that was emailed to you by selecting Use a passcode, enter the temporary passcode from email and then Enter.
  3. Select Manage my 2FA under 2-Factor Authentication
  4. Select + Add a new device.
  5. The system will walk you through the steps similar to when you first set up your phone.
  6. Once you have added your new phone, register an email address so you don't have to call the help desk in the future.  See UI Verify Recovery Email for more information.
