To enable 2FA (two-factor authentication) on Binance, do the following:

---

1. Log in to your Binance account

Via the app or website.

2. Go to 'Security'

In the app: Profile → Security.

On the website: Profile (icon at the top) → Security.

3. Choose a 2FA method

Google Authenticator (recommended — faster and more reliable than SMS)

SMS authentication

You can enable both for maximum protection.

4. If you choose Google Authenticator:

Install the Google Authenticator or Binance Authenticator app on your phone.

Scan the QR code that Binance displays.

Write down the backup key (you will need it if you lose your phone).

Enter the code from the app to confirm.

5. If you choose SMS 2FA:

Enter your phone number.

Receive and enter the confirmation code.

6. Save your backup codes

This is important — otherwise, losing your phone will make logging in a problem.

💡 Tip: It's better to enable both methods — Google Authenticator + SMS, so that if one method is lost, there is a backup.
