A FIDO2 security key is a physical device that connects to your computer or mobile device using USB or NFC. When multifactor authentication (MFA) is required, a security key is one of the more secure MFA methods available.

A security key stores your passkey. That passkey can be used instead of, or in addition to, a password. The key allows access to certain websites or applications.

Security keys are one of the most secure methods of MFA because it's impossible for a cybercriminal to steal it over the Internet. The only way this method could be compromised is if the physical key was lost or stolen, and the person who gets it knows the PIN for the security key.

Many types of security keys are available for purchase. Information Technology does not purchase or provide security keys, though we do provide a list of recommendations. Departments may opt to purchase security keys for faculty, staff, and students in their area, if desired.

After you have procured your security key, you can get started by setting up your security key with Microsoft MFA.
