Reactivate Two-Factor Authentication (TFA) on a New Mobile Device

Two-Factor Authentication (TFA) is an additional security method that Cedarville promotes in order to increase University account security for participating students, faculty, and staff. For more information, see the help page Two-Factor Authentication (TFA) FAQ.

When participants of Two-Factor Authentication receive a new smartphone (with the same phone number), the Duo Push ("Send me a Push") authentication method no longer works. To log in to your account, you must use either the Phone Call ("Call Me") or Text Message ("Enter a Passcode") authentication method. To learn how to reactive your smartphone, read the instructions below.

To Reactivate Duo Push on a New Smartphone (SAME Phone Number):

To enable the Duo Push authentication method on your new smartphone with the same phone number as your previous smartphone, you will need to reactivate Duo Mobile on your new smartphone. 

  1. Download the Duo Mobile App to your new smartphone. 
  2. Once the app is installed, go here to bring up a Duo login screen on your computer.  You can also perform these functions on your phone.  You'll just need to be able to switch between your web browser and the Duo app.
  3. On the resulting Two-Factor Login page, if your Duo account had been set to automatically send a push notification, click [Cancel] > Select the "My Settings & Devices" link under the Cedarville logo, otherwise click on the "My Settings & Devices" link.
  4. Choose the [Call Me] or [Enter a Passcode] authentication method to access your Duo account settings.
  5. On the resulting "My Settings & Devices" page, click [Device Options] next to your mobile phone.
  6. Click [Reactivate Duo Mobile] and answering the following questions. 
  7. At the end of the reactivation process, you should receive a new QR code to scan using the Duo Mobile app on your new smartphone. 
  8. At this point you should have an entry listed within your Duo app for Cedarville University and you have completed configuring your new phone for Duo.

To Reactivate Duo Mobile on a New Smartphone (NEW Phone Number): 

To reactive Duo Mobile on your new smartphone with a different phone number than your previous smartphone, you will first need to remove your old smartphone with the old phone number. 

  1. Download the Duo Mobile App to your new smartphone.
  2. Once the app is installed, log in to your CedarNet account on your computer.
  3. On the resulting Two-Factor Login page, click [Cancel] > Select the "My Settings & Devices" link under the Cedarville logo.
  4. Choose an authentication method and complete the Duo authentication. If you do not have access to any of the enrolled devices, contact a Duo Administrator to request a new activation link. 
  5. On the resulting "My Settings & Devices" page, click the  "+ Add another device" link and complete the following steps to add your new smartphone.
  6. Once you have successfully added your new smartphone, return to the "My Settings & Devices" page. 
  7. Click [Device Options] beside your old smartphone (old phone number) > Click the red trashcan [Delete] icon to remove your old smartphone. If you are unable to delete the old device, contact a Duo Administrator to request its removal.
