Note to Staff and Faculty on the Duo Mobile App

All NYU community members will greatly benefit from the many advantages of the Duo Mobile app described below. NYU staff and faculty in particular are strongly encouraged to use the app and the Duo Push feature.


  • A Duo push only requires two taps on your smartphone to approve a login.
  • Since the Duo app uses wifi, it can be used in places where there is no cellular reception, including other countries.

Generate passcodes for later use

  • The Duo app allows you to generate passcodes for later use.
  • Generate a batch of ten authentication passcodes using the app to be used for later so you're always prepared even if you don't have your phone with you.

Enhanced security

  • A Duo push uses cutting-edge, end-to-end encryption.
  • The Duo push screen displays detailed information about the application and source device that initiated the authentication request.


  • NYU is committed to reducing costs.
  • Every time you use Duo to authenticate with MFA, the University saves funds.
