IS&T provides access to Duo, a two-factor authentication application that leverages landlines and smartphones as an "Approve" or "Deny" system to identify users. Two-factor authentication is an effective way of safeguarding against security attacks, particularly related to financial data.

Duo is a self-service web application for Touchstone-enabled web applications at MIT. Integration with other applications is also available.

How to Obtain


Enroll and register your device(s) with MIT Duo at: (Touchstone authentication required)

Note: Installing the Duo Security application on your personal mobile device does not grant MIT control of your device.


Important: IS&T strongly recommends that you register a backup device for 2-factor authentication. If something happens to your phone, you'll need another way to authenticate. If you do not have another device, request a USB hardware token (YubiKey) to generate one-time passcodes for use with Duo.
