MFA-Duo - Device Options
This document lists and compares features of applications and token/fob devices that can be used to log in with MFA-Duo.
App and Device Options
Duo Mobile App
The Android or iPhone mobile application can be used with phones or tablets for any desktop or mobile authentication. See information on how to setup a Smartphone or Tablet.
Hand-held push-button devices that can be used for any desktop or mobile authentication.
Token/Fob Related Links:
A small code reader that plugs into your computer's USB port and inserts a passcode electronically during MFA login on your desktop device. Using this device as your ONLY option could lead to potential problems (e.g. logging into devices without USB ports), but it is an excellent backup or secondary MFA device. See information on how to register a U2F USB Security Key.
Note: Token/fobs and security keys are provided to faculty, staff, and students at no cost.
