The YubiKey is a device that makes multi-factor authentication as simple as possible. Instead of a code being generated by an app on your phone, you press a button on your YubiKey upon logging in. Each device has a unique code built into it, which is used to verify the login is authentic. These YubiKeys are optional and not provided by the College or LITS.

YubiKey Options


Pair the Yubikey with your Trinity Microsoft Office O365 Account:

  1. On a computer, go to and log in.
  2. Click the + ADD SECURITY METHOD tab on the top left of the list of methods you already have set up.
  3. Click the drop-down arrow and select Security Key, then USB Device.
  4. Confirm you have the key with you to set it up and continue through the remaining setup prompts.


Optional: Set Primary Security Factor

If more than one Security Factor is configured, this is how to choose which one will be used automatically.

  1. On a computer, go to and log in.
  2. You will see “Default sign-in method:“; click the blue “change” link to choose your desired default authentication method.
  3. Choose your desired default Security Factor and click confirm.
