1. What is Multi-Factor Authentication (MFA)?

Multi-factor authentication (MFA) means using more than one way to prove who you are when you log into an account. It usually involves:

  • Something you know (like a password)
  • Something you have (like your phone)
  • Something you are (like your fingerprint)

For example, after you type your password, you might get a code sent to your phone that you also need to enter.

2. Why You Need Multi-Factor Authentication

Hackers are always trying to steal passwords. If they get your password, they can get into your accounts. MFA adds another step, so even if they know your password, they still need your phone or fingerprint. This extra step makes it much harder for them to access your accounts.

Highly Recommended:- Google Authenticator.

Example: Imagine someone guesses your Facebook password. Without MFA, they cannot get in. With MFA, they also need a code from your phone, making it much tougher for them.

3. How to Set Up Multi-Factor Authentication
