What is Multi-factor Authentication (MFA)? 

MFA is an authentication technique that necessitates the usage of multiple unique "authentication factors" in order to access a system, application, or website. A security credential that confirms a user's identity when they attempt to access a specific resource is called an authentication factor.

To make sure that an individual’s data is immune to the cunning actions of hackers, MFA coordinates a blend of verification techniques.

As an advanced security step, multi-factor authentication (MFA) verifies a user's identity using a sequence of evidence, including a security token, a password or PIN, a fingerprint, or facial recognition.

A strong defense is produced by each MFA component compensating for the shortcomings of the others. The other factors remain unaffected when one is compromised. This multi-layered strategy makes sure that password guessing isn't the only way to gain access to sensitive data.  

MFA is a critical component of identity and access management (IAM). It helps minimize risks such as account takeover attacks, compromised personal data, and subsequent credential stuffing attacks.  

It reduces the risk of unauthorized access to sensitive data. After all, it’s one thing to enter a stolen password to gain access; it’s quite another to enter a stolen password and then also be required to enter an OTP that was texted to the legitimate user’s smartphone.
