What Is Two-Factor Authentication and How to Set It Up

Passwords alone are no longer enough. Two-factor authentication (2FA) adds a second verification step — usually a code sent to your phone or generated by an authenticator app — so that even if someone steals your password, they still cannot get into your account. It takes only a few minutes to set up and is one of the simplest ways to stay safe online.

On Google, open your Google Account, go to Security, then "2-Step Verification," and follow the prompts to add your phone number or an authenticator app. You can also use a hardware security key for the strongest protection.

On Apple, two-factor authentication is built into your Apple Account. On an iPhone, go to Settings, tap your name, then Sign-In & Security, and turn on Two-Factor Authentication. Apple will verify new sign-ins on your trusted devices automatically.

On Amazon, sign in, open Account, then Login & Security, and turn on Two-Step Verification. You can receive codes by text, voice call, or an authenticator app.

Whichever method you choose, store backup codes somewhere safe and keep your recovery details up to date. A few minutes of setup today can save you from a hacked account tomorrow.
