How to Set Up and Use Your YubiKey (Mac security key)

What is a YubiKey?

A YubiKey is a type of security key. Like all security keys it's a physical device that users must possess to access a system. Authentication data must flow between the user and the system to validate access (prove you are you), a security key is the conduit for making this happen.

In our case the YubiKeys are specified for use on CSUMB-issued mac computers. They must plug into the computer that you are attempting to access. 

Please note that CSUMB hardware does not support any of the biometric options (using fingerprint or face ID).

How do I get a YubiKey?

The IT Help Desk in the library will provide any CSUMB Faculty or Staff user with a security key. The YubiKeys are specific to those using CSUMB-issued Mac computers. To reserve a security key for pick up at the IT Desk in the library:

  1. Fill out the Request a Security Key Service ticket
  2. Once you have filed your service ticket, and we have verified that we have a key available for you, swing by the IT Help Desk in the library with your ticket number and we will issue you a key.

Once you have picked up your security key at the technology help desk in the library follow these instructions to set it up:
