Background
UW Madison uses Multi-Factor Authentication (MFA) to secure user logins to campus resources. MFA is a login security measure in addition to regular username/password authentication. It aims to dramatically reduce the likelihood of unauthorized access to a user’s account by requiring a user to confirm a login with a personal device, such as a phone, tablet, or token. While there are many MFA systems on the market, UW-Madison has chosen Duo Mobile as their MFA provider.
