This is a security method that requires more than one way to prove your identity. It adds extra locks to your digital door to keep hackers out.

Understanding MFA Basics

This is information only you should know, such as a password or a secret PIN. It is usually the first layer of defense for your accounts.

Something You Know

This is a physical object you own, like your smartphone or a special security token. Even if a thief knows your password, they cannot log in without this item.

Something You Have

This uses your unique body features, like a fingerprint or a face scan. Since these are unique to you, they are very difficult for others to fake.

Something You Are

A website sends a short code to your phone through a text message. You must enter this code to prove you have your phone with you.

Text Message Codes

These are apps that create a new, random code every few seconds. They provide a more secure way to log in than using standard text messages.

Authenticator Apps

These are small devices that look like a USB drive and plug into your computer. They provide the highest level of protection by requiring a physical key to enter.

Physical Security Keys

This involves using your face or fingerprint to unlock an app or website. It is a fast and secure way to verify it is really you.

Using Biometric Scans

These are a list of emergency numbers you can use if you lose your phone. You should print them out and keep them in a safe place.

Saving Backup Codes

Your phone shows a simple yes or no message when someone tries to log into your account. You just tap the screen to let yourself in.

Approving Push Notifications

These are accounts that hold your money or private messages, like your bank or email. Adding extra security to these specific accounts is the most important step for your safety.
