What are 2FA and MFA, exactly?
With a 2FA system, users are required to input two methods of identity verification (like a password and an SMS code) to access essential systems or information.
In an MFA system, users have to use more than two identifying verifications (like a password, thumbprint, SMS code and email code).
Is 2FA or MFA better for businesses?
Both 2FA and MFA have advantages and disadvantages.
Both are improvements over single-factor authentication (SFA) in almost every circumstance.
2FA is easier to use than MFA but is also less secure. On the other hand, MFA is hyper-secure but may frustrate users who have to juggle methods of authentication constantly or reenter multiple codes and passwords throughout the day.
Most businesses should use 2FA at a minimum, but MFA is highly recommended for sensitive information that may be a target for cybercriminals.
