Demand for multi-factor authentication is on the rise, and opportunities for authentication are increasing in various situations. Among them, demand for two-factor authentication, which is a similar term to multi-factor authentication, is also on the rise. Do you know the difference between multi-factor authentication and two-factor authentication? In fact, there is no difference between the two in the broad framework, but there are clear differences when you look closely.

In this article, we will explain the difference between multi-factor authentication and two-factor authentication.

What is MFA?

Multi-factor authentication (MFA) is an abbreviation for Multi Factor Authentication, and refers to a method of authentication that combines two or more of the three factors: “intellectual information,” “possessive information,” and “biometric information.” By combining these multiple factors for authentication, it is possible to strengthen security even further.

≫ [Easy-to-understand explanation] What is multi-factor authentication?

What is two-factor authentication?

Two-factor authentication is a method of authentication that combines two of the three factors: “knowledge information,” “possession information,” and “biometric information.” Since authentication is performed by combining two factors, even if one factor of information is leaked, the presence of the other factor reduces the risk of unauthorized access, and the risk of information leaks can be reduced.

Also, two-factor authentication is included in the category of multi-factor authentication, so two-factor authentication is also part of multi-factor authentication.

≫ What is the difference between two-factor authentication and multi-factor authentication? Which is more secure?

What is the difference between two-factor authentication and multi-factor authentication? Which is more secure?

We’ve explained multi-factor authentication and two-factor authentication above, but we’ll explain the clear difference between the two. The difference between multi-factor authentication and two-factor authentication is the number of factors used for authentication. Multi-factor authentication uses two or more factors to authenticate, while two-factor authentication uses a fixed two factors to authenticate. In other words, the number of factors used is the difference between multi-factor authentication and two-factor authentication.

Also, since two-factor authentication is included in the multi-factor authentication category, two-factor authentication is also part of multi-factor authentication.

Lastly

Two-factor authentication is a part of multi-factor authentication, so there is not much difference, but there is a clear difference. However, in terms of security, both are very high levels and can prevent unauthorized access in advance. Strengthen your defenses against unauthorized access by implementing multi-factor authentication or two-factor authentication on your current computers and applications.
