1 Answers

Multi-Factor Authentication (MFA) is a security method that helps protect your accounts — like your bank, email, or medical records — by asking for more than just a password when you sign in.

It’s like using two locks on your door instead of one.


Why Should I Use MFA?

Passwords can be guessed or stolen. MFA helps keep your personal information safe by adding an extra layer of protection.

Even if someone knows your password, they can’t get into your account without the second factor — like your phone or fingerprint.


How Does MFA Work?

When you log in to a website or app, MFA asks you to provide:

  1. Something you know
    → Your password

  2. Something you have
    → Your phone (for a text message or app code)

  3. (Optional) Something you are
    → Your fingerprint or face (on some devices)

You need at least two of these to log in.


Example

Let’s say you’re logging in to your email:

  • You type your password
  • Then you get a code sent to your phone
  • You enter the code to finish logging in

Now your account is much safer!


Is It Hard to Use?

Not at all. MFA usually takes just a few seconds and can save you a lot of trouble later.
It’s a small step that offers big protection.
