Note: These directions are a continuation from those on the Enroll and Set up a Device and Add a New Device pages.

When you enroll a smartphone in Duo 2FA, the smartphone will automatically be able to authenticate via push notifications (via the Duo Mobile app) and phone calls (to the device’s phone number).

Please be sure to have your Apple ID or Google Store accounts ready.

1. Select the Duo Mobile option.
2. Enter the phone number associated with the device and click Continue.
3. Confirm that the number you entered is correct OR change it if necessary.
4. Confirm that you have the Duo Mobile app on the device you are adding. When you’re ready, click Next.
5. A QR code will appear on the screen. You will be using this to add your device. There is also an option to use an activation link instead, if you prefer. (See Email an Activation Link if you do not wish to allow access to your smartphone’s camera.)
6. On your smartphone, open the Duo Mobile app.
7. On the Duo welcome screen, click Continue.
8. Select Use a QR code.
9. If your phone requests it, allow Duo Mobile to have access to your camera so that you can capture the QR code.
10. Hold your camera up to the QR code. Your device should automatically detect the QR code.
11. Name your account “Tufts University” and click Save to complete the setup process.
12. Back on your computer, you should see confirmation that the activation is complete.
    
    If you just enrolled in Duo 2FA and this is the first device that you are adding, please return to the page on how to Enroll and Set Up a Device and continue from there! Otherwise, proceed to the next step.
     
13. Click Continue to close the popup window.
14. The added device will be displayed on the device management page. (Tip: If you have multiple devices enrolled in Duo, you may want to give this device a more specific name. For more information, see directions for Changing a Device’s Display Name.)
