Multifactor Authentication (MFA) requires users to provide multiple forms of verification to access a system. This method significantly increases security by requiring two or more independent credentials, combining something the user knows, something the user has, or something the user is. This setup blocks unauthorized access more effectively than methods relying on a single authentication factor.
