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 best practices

Key Importance:

• Treat your security key with the same importance as a car key.
• Do not inscribe your name or any other meaningful personal information on the key. This includes stickers or keychains that contain said personally identifiable information.

PIN Security:

• A PIN is mandatory and should not be simplistic, such as “000000” or “123456.”
• Avoid writing the PIN on a sticky note; instead, create a memorable code that doesn’t require physical or electronic documentation.
• Do not disable interfaces to circumvent the PIN prompt.
• The minimum PIN length is 6 characters, with a preference for 8 or more alphanumeric characters.
• PINs must not contain any personal identifiers like Employee ID, Social Security number, phone number or any details related to the key owner.

Key Custody:

• Never leave your YubiKey or other security key unattended.
• When traveling, keep the key separate from your laptop; for example, if the laptop is in a bag, carry the key in your pant pocket, purse or another carrying method.

Key Storage:

• Upon stepping away from your laptop or computer, remove the key and store it securely, preferably on your person.
• Do not keep your security key attached to your name badge/University ID card.

Public Use Precautions:

• In public settings, be cautious of onlookers when entering your PIN. Physically rotate yourself 90 degrees to shield the PIN entry from view as you type it.

Authentication Methods:

• After both the security key and the Microsoft Authenticator application have been configured on the account, visit to remove the SMS and phone call authentication options from your account. These methods are less secure.

Loss Prevention:

• In case of a lost or stolen key, report it immediately to the Division of IT by contacting the IT Help Desk.
• And as soon as possible remove the security key as an authentication method from your account.
• Login to with your alternative multi-factor method (i.e. Microsoft Authenticator.
• Select “Security info.”
• Click on “Delete” next to security key/method for the device that was lost or stolen.
• Click “OK” to confirm deletion of security key.
