At Clarkson we are using Duo for Two-Factor Authentication, an advanced method for securing your accounts and verifying your identity on Clarkson systems.  It works by utilizing an additional form of account protection such as a cell phone or separate hardware token in addition to your username and password.  This prevents anyone but you from accessing your Clarkson resources even if your password becomes known.

Currently we support three forms of additional authentication:

  1. Push notifications on a cell phone through the Duo app, also known as a "Duo Push" (Strongly Recommended)
  2. Entering a security key generated by the Duo app on your cell phone
  3. Entering a security key generated by a Duo hardware token
For options 1 and 2, please follow the setup instruction below, labeled "


Up Duo using your mobile Device."  While we strongly recommend using the Duo app on a mobile device, if you prefer to use a separate Duo hardware token, please contact the IT HelpDesk to schedule a time to pickup a hardware token and have your account configured.Setting
