One of the safest authentication techniques is multifactor authentication (MFA). It includes a wide variety of subjects in a cyber-connected environment, including control of access rights, communications, and online payments. Due to the extra step the user must do, multifactor authentication is typically a little difficult. With two-factor authentication, in addition to the user ID and password, the user must also enter a unique code, often sent to them through SMS or one they have already obtained. This essay will discuss the idea of MFA, the main distinctions between MFA and two-factor authentication (2FA), the advantages of MFA, and the need of using it
