Setting Up Multi-Factor Authentication using a FIDO2 Security Key

Last modified 7/23/2026

The University is now allowing the use of FIDO2 security keys as an option for Multi-Factor Authentication (MFA). These security keys provide the most secure form of authentication by replacing standard password-based authentication with hardware-based authentication and a unique PIN. To set up this method, you will need to purchase your own FIDO2 security key. Please see the following link for a list of all compatible Microsoft security keys. If you have not yet enabled MFA on your account, please refer to the steps in the Enabling Multi-Factor Authentication article.

Registering Your Security Key

Depending on the security key you choose, there may be additional steps before it can be registered. Please see your key's manufacturer's instructions for any setup or troubleshooting information. 


Registering a FIDO2 Security Key as a sign-in method


1. Head to the MFA Security Info portal, sign in normally, and click Add sign-in method.

Multiple MFA verification methods are recommended.

It is recommended that you set up at least two methods of multi-factor authentication, so you have a backup if one fails. Please see Adding Additional Verification Methods for Multi-Factor Authentication for instructions on setting up additional method(s). To change your default method, see Change the Default Method for Authenticating with MFA. Below are the three main options for verification:
