What is Two-Factor Authentication?

2FA requires two forms of identification to log in — typically your password and a temporary code sent to your phone or app.
It drastically reduces the chances of someone accessing your account even if they know your password.

Best 2FA Apps to Use

– Google Authenticator
– Authy
– Microsoft Authenticator
– Duo Mobile

All of these apps are free and work on iOS and Android.

How to Set Up 2FA on Common Platforms

1. Gmail: Settings → Security → 2-Step Verification
2. Facebook: Settings → Password and Security → 2FA
3. PayPal: Settings → Security → 2FA Setup
4. Instagram: Settings → Privacy → Two-Factor Authentication

Tips for Safe Use

– Never share your codes
– Keep backup recovery codes in a safe place
– Use app-based 2FA instead of SMS when possible

Conclusion

It only takes 5 minutes to set up 2FA — but it could save your identity. Make it a habit for every account you care about.
