Something you know + Something you have

DUO will be required to access the CSU VPN services (using both the Pulse Client and secure.colostate.edu) on April 25, 2018.

What is it and why use it?

Duo is a tool that provides two-factor authentication to better protect your account by requiring an additional piece of information beyond your username and password. When you log into a protected service using your Colorado State University’s single sign-on, you will be required to use a device that you have (your mobile phone, desk phone, a hardware token, or other device) to provide an additional layer of security to your account. This is done by using the Duo Security app (on your smartphone) and receiving a push authentication request, or through a phone call or entering a generated code.
