MFA stands for Multi-Factor Authentication. It is an additional layer of account security that requires two factors of information to verify your identity. These factors usually include something you know (like a username and password) plus something you own (like a cell phone) to prevent unauthorized users from accessing your account even if your password has been stolen or compromised. Many different methods of MFA are available today. The most common is to receive a verification code via text message that must be used during the login procedure along with your password. There are also several smartphone apps, such as Google Authenticator and Okta Verify, that can be downloaded from the app store to generate the single-use login code. Physical hardware tokens are another alternative option for MFA. However, not every MFA method is supported by MyWisconsin ID, so it is important to select from verified options. For example, while the Okta Verify mobile app is supported, the PC version for both Windows and macOS is not a valid option.
