Duo two-factor authentication (2FA) at UConn is designed to be used anywhere in the world at any time. The simplest way to use 2FA for UConn services when you are outside of the United States is to download and set up the Duo Mobile app for authentication. Duo Mobile works both with or without internet access on your device and is ITS’s recommended second-factor authentication method for all situations. There are two key reasons to use the Duo Mobile app:

  • By using the Duo Mobile app, you avoid international charges for any data usage, SMS text messages, or phone calls from Duo that are delivered over international cellular networks.

  • As long as you have the same device, the app will continue to work, even if you change your phone number.

Travelers may also consider using a hardware token. These tokens never require any kind of service (cellular or internet).

New to Duo?

If you are you setting up Duo for the first time, follow the instructions for setting up a mobile phone for 2FA and installing the Duo Mobile app.

Switching from Text to the Duo Mobile App

To follow this process, you must have access to the original number that you added to Duo.

It’s best to follow these steps on a computer because you need to scan a QR code at the end of the process. If you need to follow these steps on your mobile device, you can instead use the activation code.

If you already have Duo set up on your mobile device but did not install the app on your phone, follow these steps below.

  1. Download the Duo app

    1. Download: iOS App Store

    2. Download: Google Play Store

    3. After downloading the app, you do not need to open the app.

  2. Visit Device Management Portal and sign in with your NetID and NetID password.

  3. Click on Manage Devices and enter your UConn email address and then enter your NetID password.

  4. Click on Add a device.

  5. Choose Duo Mobile.

  7. Click Next if you have already installed the Duo Mobile app.

  8. Open the Duo Mobile app and click on + Add then click on Use QR code.

  9. Scan the QR code with your phone’s camera.

  10. The new account will be added to Duo as “University of Connecticut”. You may leave this name as it is.
