MFA-Duo - How to Use a U2F USB Security Key
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.
The security key allows MFA-Duo users to insert the security key into the USB port of their computer or laptop to authenticate. This security key requires a reachable USB port, but this security key also works with a laptop or desktop USB to USB-C adaptor. The key is not compatible with mobile devices and only works with laptop or desktop computers.
The security key experience is slightly different for the following modes of logging in. See below for details on these modes.
Chrome web browser login
When logging in to a UW-Madison website or apps using Chrome (version 70 or later), insert the security key into your USB port, select Security Key (U2F) from the device dropdown menu, and lightly touch the impressed sensor button to initiate login.
Non-Chrome web browser or local software login
When logging into a UW-Madison website or app in Firefox or Safari, insert the security key into your USB port. Select Token from the device dropdown menu, and click the "Enter passcode" button to make the passcode input field editable. Then lightly touch the impressed sensor button to insert the passcode in the input field. If you are using a screen reader or other assistive technology, the security key may enter the passcode so quickly you may not hear the full code. The audio cue may only include the last digit of the code. Click the login button to complete authentication, as the full code should have populated the field.
