Multi-Factor Authentication (MFA) - Duo

Multi-Factor authentication (MFA) is an online security system for your sensitive and personal information. It requires more than just a password for access. The goal is to create a layered defense for your data so that an unauthorized person finds it more difficult to access. If your password becomes compromised, there will be another level of security to keep your information safe.

BSC uses Duo Security MFA to provide you with even better security for your sensitive information.

How do I enroll in Duo Multi-Factor Authentication (MFA)?

When logging into a Duo protected application such as Microsoft 365, Blackboard, Duo Device Management , and the NDUS Portal using your NDUS credentials, you will be prompted with Duo. If you are not already registered you will be prompted to do so (this is "in-line" enrollment). You can also go directly to 2fa.ndus.edu to enroll.

Welcome to Duo Security

You will be prompted to add your first device to Duo. Your available choices will depend on the device you are currently using. Windows Hello is shown on a Windows computer. A Mac computer will have touch ID. Mobile devices will have touch ID or face ID.

Note: We highly recommend setting up the mobile app to enable the Push option which works either via wifi or mobile data as well as setting up Windows Hello or Touch ID on your computer in case your mobile device is not available.

Duo Multi-Factor Authentication FAQ

What if I receive an unexpected Duo authentication prompt?
If you receive a Duo authentication prompt (push, text, or phone call) on your device without you initiating the request, decline the Duo prompt (marking it as fraud), immediately change your NDUS account password, and contact the BSC Help Desk. This could be an indication that your credentials have been compromised and someone is attempting to login to your account.

Can I have multiple phones or devices for Duo authentication?
Yes, you can have multiple phones and devices registered in Duo. It is recommended to have multiple options registered to be used in the case your preferred device is unable to be used. The NDUS has a help article How to add devices to Duo will show you how to add or make changes to devices.

What if my phone doesn’t have Wi-Fi or cellular service?
You can open the Duo Mobile app and generate a 6-digit passcode to use with Duo authentication, since this works without cell or network service. The NDUS has a guide on how to obtain a passcode from the app How to use Duo mobile - passcode.
