What is Multi-factor Authentication (MFA)?

Multi-factor Authentication (MFA) also known as two-factor authentication (2FA) is a security enhancement that helps us to add a layer of protection to the sign-in process. Enabling Multi-factor authentication prevents stealing your information from hackers/criminals. Microsoft supports multi-factor authentication in its products and services including Office 365.

Why MFA or two-factor Authentication is used?

By setting up Multi-factor Authentication MFA, we can add an additional layer of security to your Microsoft 365 account sign-in. When we enable MFA for our Office 365 accounts and try to log in then, first we need to enter our password and, also type a dynamically generated verification code sent to the registered number. Remember one thing before enabling MFA you must be a Global admin to manage MFA.
