Enrolling in and Using MFA

Follow the instructions below to start benefiting from the additional security provided by NYU Multi-Factor Authentication (MFA).

TIP: For the best MFA experience, enroll two or more devices and use the Duo Mobile app to easily authenticate even without cell or Internet service and when traveling. See below for instructions.

What Is Multi-Factor Authentication (Duo)?

Multi-Factor Authentication (MFA) adds a second layer of security to help prevent anyone other than you from accessing your sensitive information online. This is accomplished using two types of authentication to verify your identity when logging into a system.

  1. First, you need to log in with your password—something you know—and username (usually your NYU NetID).
  2. Second, you use a physical device—something you have with you when you log in—such as your mobile phone, tablet, or landline phone, to confirm your identity.

The device that is most convenient for this purpose is a mobile phone with an MFA app installed on it. Alternatively, an SMS text message can be sent with a series of one-time passcodes for you to type in. Or, you can receive a phone call.

The service NYU uses for MFA is called Duo.
