Setting up DUO Mobile


As a student you are enrolled in DUO Mobile automatically. You can approve login requests by answering the phone call on your smartphone. However installing the DUO Mobile app on your phone is much more convenient.


Download the Duo Mobile App for your Android Device or iPhone

To start enrolling a new device, log into https://2fa.ndus.edu. Choose an authentication method and complete multi-factor authentication to begin adding a new device. click "Add a new device" on the left hand side.


Click that link and follow the instructions. You should end up seeing a QR code on your screen that you can then scan with your phone's camera to enable your smartphone as your second form of authentication.

What's Next?

Every time you login to your NDUS account to access sensitive information you will be required to verify your identity using your smartphone. You will receive a notification from the Duo Mobile app, simply tap that notification and you will be prompted to either Allow or Deny the login attempt.
