Body
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. 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.
Duo is the 2FA option used for securing login access to online University systems, such as those accessed via the U-M Weblogin page, or CAEN remote access services. All that is needed to get started is to choose and enroll your device(s).
Refer to the U-M Safe Computing website for more information on using Duo Two-factor Authentication at U-M.
