Duo's self-enrollment process makes it easy to register your phone or tablet and activate the Duo Mobile application so you can receive Duo requests via push notification and tap to approve and login. This self-enrollment process can be done prior to the Duo "go live" date. If you do not enroll prior to that date, Duo will prompt you to enroll the first time you log into into a protected VPN or web application.
These seven quick steps are shown in the video below and will only take a few minutes. If you need additional help, a full step-by-step Enrollment Guide is provided by Duo.
