What is MFA?

This article covers the importance of MFA, implementation best practices, and troubleshooting tips.


What is Multi-Factor Authentication (MFA)?


Multifactor Authentication (MFA) is an authentication system that requires more than one distinct authentication factor for successful authentication. It can be performed using a combination of authenticators providing different factors, such as something you know (e.g., password), something you have (e.g., token), and something you are (e.g., biometric)[1][2].

MFA enhances security by requiring users to provide two or more verification factors, reducing the likelihood of successful cyber attacks compared to traditional password-only methods[4]. The factors used in MFA include knowledge-based authentication, possession-based authentication, and inherence-based authentication[5].

The importance of MFA lies in its ability to increase confidence that the right individual is accessing the right system or service, thereby reducing security risks associated with compromised passwords and unauthorized access[3]. By combining multiple factors, MFA creates a layered defense making it more challenging for unauthorized individuals to breach systems or accounts[2].

In summary, MFA is a crucial component of identity and access management policies, offering enhanced security by requiring users to provide multiple verification factors during the authentication process[4].

How does Multifactor Authentication enhance security compared to traditional password-only methods?


Multifactor Authentication (MFA) significantly enhances security compared to traditional password-only methods by requiring users to provide multiple verification factors during the authentication process[1][2]. Here are some key points illustrating how MFA improves security:


Layered Defense

MFA creates a layered defense by combining two or more independent authentication factors, such as something you know (password), something you have (token), and something you are (biometric)[1]. This multi-layered approach makes it more challenging for unauthorized individuals to gain access even if one factor is compromised.

Reduced Risk of Unauthorized Access

MFA reduces the risk of unauthorized access and data breaches by adding an extra layer of security beyond just passwords[3]. Even if a password is compromised, the additional factors required in MFA act as barriers to prevent unauthorized entry.

Increased Confidence in User Identity

By requiring multiple factors for authentication, MFA increases confidence that the right individual is accessing the system or service, thereby reducing security risks associated with compromised passwords[5].

Phishing Resistance

MFA helps mitigate phishing attacks as it requires more than just stolen credentials for unauthorized access[2]. Even if attackers obtain a user's password, they would still need additional factors to successfully authenticate.

Adaptive Security

Adaptive MFA dynamically adjusts authentication requirements based on various factors like user behavior, location, and device used, enhancing security while maintaining user experience[2].


In summary, Multifactor Authentication offers a robust security mechanism that goes beyond traditional password-only methods, providing enhanced protection against cyber threats and unauthorized access attempts[4].

What are the different factors typically used in Multifactor Authentication?


Multifactor Authentication (MFA) requires two or more independent authentication factors for successful authentication[1][2]. The three most common categories, or authentication factors, used in MFA are:


Something you know

This includes passwords, PINs, combinations, code words, or secret handshakes[4]. It is something that the user knows and can recall when needed.

Something you have

This includes physical objects such as keys, smart cards, USB drives, and token devices[4]. A token device produces a time-based PIN or can compute a response from a challenge number issued by the server.

Something you are

This includes any part of the human body that can be offered for verification, such as fingerprints, palm scanning, facial recognition, retina scans, iris scans, and voice verification[4][5]. It is a biometric factor that is unique to the individual.


MFA works by combining two or more factors from these categories to create a multi-factor authentication process[4]. By requiring multiple factors for authentication, MFA enhances security by reducing the likelihood of successful cyber attacks compared to traditional password-only methods[3].

In summary, the three most common authentication factors used in MFA are something you know, something you have, and something you are. By combining these factors, MFA creates a layered defense that makes it more challenging for unauthorized individuals to gain access even if one factor is compromised[2].
