[Purpose] Explain the purpose of multi-factor authentication Explain the background to the need for multi-factor authentication
Purpose of Multi-Factor Authentication
Do you know the purpose of multi-factor authentication? It’s been a while, but when logging in to an application or website, in addition to your ID and password, you may have had to go through several authentication procedures, such as receiving an authentication code via SMS (short message) or email. In fact, this authentication is not multi-factor authentication, but rather two-step authentication, which is a type of multi-step authentication. The main reasons for the introduction of two-step authentication are to prevent unauthorized access through SNS and other sites, and to strengthen security.
So, what is the purpose of multi-factor authentication that is attracting attention? Its purpose is to further strengthen security than two-factor authentication. The difference between two-factor authentication and multi-factor authentication is that two-factor authentication is an “authentication method in which authentication is performed twice,” while multi-factor authentication is “a method of authentication that combines two or more factors.” Therefore, with two-factor authentication, there is no need to combine factors if you can authenticate twice, whereas with multi-factor authentication, you need to combine two or more factors for authentication. Therefore, multi-factor authentication has a higher level of security than two-factor authentication. In addition, authenticating by selecting two of multiple factors is called “two-factor authentication (2FA).” By the way, there are currently four types of factors listed as multi-factor authentication factors: “information in possession,” “intelligence information,” “biometric information,” and “location information.”
As such, multi-factor authentication differs from two-factor authentication in that it has more authentication factors. The more authentication factors there are, the higher the security will be, and the more effective it can be in preventing unauthorized access and logins. For these reasons, multi-factor authentication has recently been attracting attention, following two-factor authentication.
In the future, we expect to see an increasing number of services released that enable multi-factor authentication. By introducing a service that suits your company and preventing unauthorized access and information leaks, you can ensure the safety of your company and build trust with your business partners.
