What is multi-factor authentication?

mul - ti - fac - tor au - then - ti - ca - tion
noun

Multi-Factor Authentication (MFA) is a security measure that verifies the user's identity before gaining access into their accounts or systems. By using different ways to confirm identity, such as passwords, codes from your phone, or even your fingerprint, MFA adds an extra layer of protection against hackers or fraudsters impersonating you. It's like having multiple locks on a door to make it harder for intruders to get in. This way, your personal information and accounts remain secure and mitigate any instances of identity theft.
 

How does multi-factor authentication work?

Multi-factor authentication (MFA) adds another layer of security when you log into accounts online. The system verifies you are who you really say you are, by providing at least two methods of authentication:

Something You Know: This is usually a password only you know.
Something You Have: It's a thing you own, like your phone. Using third-party apps, you can obtain a special code or one-time passwords (OTP).
Something You Are: This usually refers to a biometric marker, such as your fingerprint or face.

So, when you log in at first, you enter your password. Then, you might need to use your phone to obtain a special code, or use your fingerprint. This way, even if someone guesses your password, they can't get in because they don't have your phone or fingerprint. It's like having a secret handshake that only you can do. This helps keep your accounts safe from individuals with ill-intent.
