Duo Security

What is Two-Factor Authentication?

Two-factor authentication is one of the best ways to protect against remote attacks such as phishing, credential exploitation and other attempts to takeover your accounts.

What is Duo Security?

Duo Security is a company that provides two-factor authentication to Faculty/Staff that have access to highly sensitive GVSU information through VPN.GVSU.EDU .

Two-factor authentication provides a second layer of security to any type of login, requiring extra information or a physical device to log in and verify your identity, in addition to your password. This prevents anyone but you from accessing your account, even if they know your password.


The factors may include:

Something you know: A unique username and password

Something you have: A smartphone with an app to approve authentication requests

Something you are: Biometrics - like your fingerprint or a retina scan

Why do we need two-factor authentication?

Login credentials are more valuable than ever and are increasingly easy to compromise. Over 90% of breaches today involve compromised usernames & passwords. 

If you are required to participate in Duo Security, you will receive an invitation from IT. Then read the guide and follow the the set-up instructions. Duo does not replace or require you to change your username and password. Think of Duo as a layer of security added to your pre-existing login method.
