Activating two-factor authentication (2FA) on Binance is an excellent way to protect your account. Here is a step-by-step guide to do it with Google Authenticator:
1. Log in to your Binance account from the app or the website.
2. Go to your profile (icon in the top right corner) and select *“Security”*.
3. In the two-factor authentication section, click *“Activate”* next to “Authentication app.”
4. Binance will show you a QR code and a setup key. Open the Google Authenticator app on your mobile and scan the QR code or enter the key manually.
5. Save the backup key in a safe place. It will help you if you lose access to your device.
6. Enter the 6-digit code generated by Google Authenticator in Binance to confirm the linking.
7. Done! Your account now has 2FA activated.
