MFA-Duo - How to Use a U2F USB Security Key
This document demonstrates using a Security Key, also known as Universal 2-Factor (U2F) device, to authenticate to MFA-Duo.
Security Key (U2F) authentication is only supported in the Google Chrome browser. We strongly recommend that you have a mobile device and/or token registered to MFA, and use U2F authentication as a secondary method.
When an MFA prompt appears, be sure that the Security Key option is selected, and that your USB device is plugged into your computer.
Tap the button on your U2F device and the authentication will take place automatically.
If you run into any issues or have any questions, please contact the DoIT Help Desk.
