Duo - Reactivation

Do you have a new smartphone or device? Did you accidentally delete the Duo Mobile app or reset your phone? With Duo's self-enrollment portal, you can reactivate Duo on your phone with a few steps. If you have a new phone number and your old number no longer works, you will need to contact the CCIT Support Center.

If you have the same number, you will need to visit Clemson's Duo Device Management Portal at https://2fa.clemson.edu to reactivate Duo.

Supported Browsers: Chrome, Firefox, Safari, Internet Explorer 8 or later, and Opera.

1. Go to https://2fa.clemson.edu and click on Manage Devices. You will then need to log in with your Clemson username and password.



2. Choose Your Method.

If you do not have the app, you will not be able to receive a push. So click Call Me or Enter a Passcode. The passcode feature will then text you a passcode that you can enter here, or you may have a passcode provided by the CCIT Support Center.

3. Once you've authenticated via call or passcode, click Device Options for the device you would like to reactivate.


4. Click Reactivate Duo Mobile.


5. Choose Platform.

Choose your device's operating system and click Continue 

 

6. Install Duo Mobile.

Follow the platform-specific instructions on the screen to install Duo Mobile. After installing our app return to the enrollment window and click I have Duo Mobile installed.

 

 

7. Activate Duo Mobile.

Activating the app links it to your account so you can use it for authentication. 

On iPhone or Android, activate Duo Mobile by scanning the barcode with the app's built-in barcode scanner. The Duo app may ask for access to your device's camera. You should choose allow in order to successfully scan the barcode.

Follow the platform specific instructions for your device. The Continue button is clickable after you scan the barcode successfully. 

Can't scan the barcode? Click Or, have an activation link emailed to you instead and follow the instructions.


8. Configure Device Options (optional).

You can use Device Options to give your phone a more descriptive name, or you can click Add another device to start the enrollment process again and add a second phone or another authenticator.

If this is the device you'll use most often with Duo then you may want to enable automatic push requests by changing the When I log in: option and changing the setting from Ask me to choose an authentication method to Automatically send this device a Duo Push or Automatically call this device and click Save . With one of the automatic options enabled Duo automatically sends an authentication request via push notification to the Duo Mobile app on your smartphone or a phone call to your device (depending on your selection).

Congratulations!

Your device is ready to approve Duo authentication requests. Click Send me a Push to give it a try. All you need to do is tap Approve on the Duo login request received at your phone.
