What is two-factor authentication (2FA)? What is Duo?

Two-factor Authentication (2FA) is a security tool used to mitigate the threat of online attacks. It provides an added layer of protection by requiring an additional security check, in addition to your password, when logging into your computing account. For example, it is especially useful in preventing malicious intruders from accessing online resources using stolen or hacked passwords, such as those obtained via phishing attacks or malware.

In addition to using Duo for securing login to CAEN remote access services, it is also used as protection for access to other online University systems via the U-M Weblogin page. Doing this will help protect web-based access to your online University data, including:

  • Personal information in Wolverine Access, such as enrollment and payroll
  • U-M Google services, such as email and drive storage
  • U-M Box storage
  • Canvas course data


Refer to the U-M Safe Computing website for more information on using Duo Two-factor Authentication, including their own set of frequently asked questions.
