Duo Setup: Smartphone

A majority of campus users have their own personal devices which makes access to two-factor authentication simple. Smartphones utilize the Duo Mobile app which uses very little data and storage. If you do not have a smartphone or cannot install the Duo Mobile app, ITS can provide you with a hardware token (sometimes called a "fob") to use instead (see our guide on the Duo fob for more information - link opens in a new tab).
