What is Multi-Factor Authentication?
Multi-factor authentication (MFA) is a security mechanism that requires users to provide two or more forms of authentication before being granted access to a system or application.
By requiring multiple factors of authentication, MFA can significantly increase the security of user accounts and reduce the risk of unauthorized access, even if a user's password is compromised.
Important Note
