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 University resources using stolen or hacked passwords, such as those obtained via phishing attacks or malware.
The University of Michigan recently adopted Duo as its two-factor authentication solution. Any U-M student, faculty, or staff member can enroll in Duo at no cost. In addition to using it for securing off-campus login to CAEN remote access services, it may also be used to protect access to other University systems that use the U-M Weblogin page. Doing this helps 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
