How do I use Two Factor Authentication without a phone?

The C&IT Help Desk sells the YubiKey 4, a USB authentication key that may be used in lieu of a push notification or pin number to satisfy Two-Factor Authentication.


The authentication key is designed to stay plugged in to a user's computer and provide Two-Factor Authentication access. This option is best served for those who are heavy users of administrative services which require multiple Two- Factor Authentication verifications.
