Multi-Factor Authentication
Multi-Factor Authentication (MFA) protects your account by adding an extra layer of security to your account. In addition to your user name and password, you need to submit a second type of authentication that will verify that you are authorized to access the system.
If your account is configured for MFA, the first time that you log in, you will be prompted to enroll in an authentication method. We recommend that you configure more than one authentication method.
Once you're enrolled, each time that you log in to your account, after you enter your user name and password, you will be prompted to authenticate your account by using one of the methods you set up.
