What is Two-Factor Authentication (2FA)?

It’s an extra layer of security—after you enter your password, you also enter a code from your phone, an app, or a hardware key. This makes hacks and breaches almost impossible.

How to Set Up 2FA in Minutes

1. Go to Security Settings for each major account (Google, Apple, Facebook, Instagram, bank apps, Amazon, etc.).
2. Find the option for Two-Factor Authentication or 2-Step Verification.
3. Choose your method. Best: Use an authentication app like Google Authenticator, Authy, or Microsoft Authenticator. Avoid SMS codes if possible.
4. Scan the QR code displayed on the site with your authentication app.
5. Enter the code shown on your app to confirm setup.
6. Save your backup codes in a safe place (not on your phone or desktop).
