Duo | What Is Multi-factor Authentication and Why Do I Need It?

When to Use?

Multi-factor Authentication (MFA), commonly referred to as Two-Factor Authentication (2FA) provides an additional layer of security for users logging in to a secure environment.

MFA leverages multiple types of authentication:

  • Something you know (GVSU Network ID & password)Computer and cellphone infographic for Duo setup
  • Something you have (physical device)
  • Something you are (e.g. fingerprint, facial recognition)

GVSU uses Duo Security as its MFA solution. Duo makes authentication easy by allowing individuals to verify their identity using a mobile device - either through an app or using a code sent via text. 


Why do I need it? 

We have been using Duo for Multi-factor Authentication (MFA) since 2016 to secure connections to GVSU's VPN. Due to the prevalence of malware incidents across our nation, security requirements continue to evolve. In addition, GVSU's cyber insurance providers are now mandating MFA. In light of that, we will be rolling out MFA for all faculty and staff applications. The initial timetable and list of current applications are at the bottom of this page for your reference.  Also, all new services/applications deployed by the IT department will require MFA. For student-facing applications, MFA will be rolled out following the completion of faculty and staff applications.

Do I need a cell phone?   

The Duo mobile push option is the preferred method as it is the fastest and requires no additional cost. In addition, the SMS text and Phone call options are available when needed but cost the university money each time they are used. Therefore, the push option is highly recommended.
