AMulti-factor authentication (MFA) is a security feature that do impose multiple authentication methods of credentials to verify the identity of a user who’s trying to login. Multi-factor authentication has two or more independent credentials. What the user knows, such as a password. What the user has, such as a security token. And what the user is, which is using biometric verification methods.
Why is multi-factor authentication important?
On of the main weaknesses of the usual username and password combinations is that passwords are easily compromised and exposed, Causing great damage to organizations. Password-Guessing attacks are a dangerous threat because many malicious users are using tools to automatically submit multiple combinations of random usernames and passwords until they get a successful hit. This is where the importance of MFA comes into place, helping employees to reduce attack risk and surface for their accounts.
Multifactor authentication vs. two-factor authentication
When authentication methods were first implemented, the goal was to tighten up security and keeping the login process simple. Users were prompted to submit only 2 kinds of security keys that authenticate authorized individuals. The most known form of 2FA were username ID and Password.
Sadly, attackers uncovered ways to expose those passwords. So this pushed companies and security vendors to look into more strict methods of user authentication that used additional security factors for verification.
