Getting started

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.
