MFA Security Keys

What is a security key and how do you set one up?

What is a security key?

Security keys are a convenient alternative to using your cell phone, office phone or email to handle the Multi-Factor Authentication (MFA) system currently being used by the university. These easy-to-use keys help get you logged into your computer, provide fast access to websites and applications, and are more secure than other modes of authentication. Security keys help to protect against account takeovers, online attacks and phishing attempts. 

When selecting a security key:

• Choose keys that necessitate physical touch to operate, ensuring active participation in the authentication process.
• Do not use nano-sized keys to prevent them from being left in the computer, especially for laptops. The larger size reduces the risk of forgetting the key in the device and causing physical damage when transporting the laptop.

If you would like to use a security key, you must purchase one. Departments may also purchase security keys for their employees if they wish by contacting their IT staff.  We recommend purchasing one of the following security keys:

• Security Key NFC by Yubico – This is the best choice for most users
• YubiKey 5C NFC or YubiKey 5 NFC

Setting up a security key

The registration process to set up a YubiKey is the same for Windows, MacOS (using a Chrome browser) and mobile devices. However, MacOS requires that a PIN be set on the security key prior to registering the key with Microsoft. Scroll down for instructions for setting a PIN on MacOS.
