MFA: What Is It and How Does It Work?

When it comes to digital security and authentication, having multiple layers of protection is always key. MFA, or Multi-Factor Authentication, is a form of enhanced security designed to identify users and ensure that the account isn’t accessible by those not authorized to access it. In this article, we’ll be taking a closer look at what MFA is and how it works.

MFA and the Principles of Authentication

MFA is based on the principles of authentication: proving that the user accessing the account is who they say they are. This process is done through the use of something a user knows (like a password, PIN, or secret question/answer), something they have (such as a token, ID card, or biometric data), or something they are (such as a biometric data or facial recognition). MFA takes two or more of these authentication methods and combines them to create a more secure authentication mechanism.

MFA Verification Process

MFA typically follows a two-step process. The first step is the user providing the login credentials, usually a username and/or password. This provides the initial identity verification. Then, after the user is successfully authenticated, the second step starts. This is the MFA process, and it can be done via a text message or email code sent to the user, a biometric scan, or a hardware or software token. Once the user successfully submits the authentication token, their identity is again verified and the user is granted access to the account.

Benefits of MFA

MFA is well worth the extra step or two for users to log in to their accounts, as the added layer of security can significantly reduce the chances of being targeted by hackers. MFA can also reduce the risk of account takeover, as it limits the options attackers have if they manage to get their hands on the user’s login credentials. Furthermore, as MFA requires the use of additional verification methods, it restricts the ability of hackers to use automated software to access the account.

Conclusion

Multi-Factor Authentication is an extra layer of security that can help make your accounts more secure. MFA is based on the principle of authentication, which proves that the user of the account is who they say they are. It typically follows a two-step process and provides an additional layer of protection against malicious actors. Implementing MFA on online accounts may add an extra step for the user, but it is well worth the extra effort for the added security it provides.
