What is MFA?
Multi-factor authentication (MFA) is a security measure. Many of you are familiar with it from accessing your banking website, Google email, or other secure websites.
MFA requires you to provide a unique code (communicated to you as a text, phone call, or via an authenticator app) after entering your username and password. MFA is used to verify that you are you.
