Duo MFA Challenges: Do not approve Duo challenges to logins if not currently expecting one. 

1. Select your device and authentication method

The Duo prompt at https://2fa.ndus.edu lets you choose how to verify your identity each time you log in. Select the device you want to use and then choose your authentication method.

  • *You'll also see a  Remember me for...  option. If you check this box when authenticating you will not need to re-authenticate within that time frame unless you change browsers, devices, or clear browser cache/cookies. If your browser clears cache automatically when sessions are closed, you may need to adjust browser settings to allow this option to function.

Duo Login Screen

Send Me a Push

Pushes a login request to your phone or tablet for approval. Just review the request and tap Approve to log in.

*Requires the Duo Mobile app installed and activated on an iPhone, Android, or Windows Phone device

Call Me

Authenticate via phone callback. The caller will be prompted to press 5 to approve the login. Why might Duo phone callback authentication fail to Chinese +86 numbers?

Enter a Passcode

Log in using a passcode, either generated with Duo Mobile, sent via SMS, or provided by an administrator. Click Send codes to get a new batch of passcodes texted to a mobile device.


Click into the passcode entry field and tap the token to generate and submit a passcode.
