How to Use BAuthenticator for 2FA on the Binance App?

Two-Factor Authentication (2FA) is a multi-layered security mechanism, designed to verify the identity of a user before granting them access to an account. It adds an additional layer of protection against unauthorized access.

2FA is particularly crucial for safeguarding your crypto assets and Binance account. Even if a hacker manages to obtain your password, they would still need the second factor (e.g., Google Authenticator) to gain entry to your account, making it considerably more challenging to breach your security.

1. Log in to your Binance app and tap the [Account] icon. Tap the profile section at the top and go to [Security].

2. Tap [Authenticator App] - [Enable].

3. You’ll see a QR code and a setup key. Copy the setup key. Do not tap [Next] before the BAuthenticator setup is complete.

Open your BAuthenticator app and tap [Scan QR code] to scan the QR code. If you’re unable to scan it, tap [Enter a setup key] and enter the code manually. You should see a new account named “Binance.com” added to your BAuthenticator.

4. Go back to the Binance app and tap [Next] to proceed.

5. Verify your BAuthenticator by entering the 6-digit code generated by the app.

6. You have successfully enabled BAuthenticator for your Binance account.

1. You may swipe left on the code to [Pin], [Edit], [Export], or [Delete] an account.

2. Tap the [+] button on the top right corner to add multiple accounts to your BAuthenticator.

3. To customize the name of an account, swipe left on the 2FA code and tap [Edit].

4. You may export an account tied to your BAuthenticator to another device. Tap [Export] and scan the QR code with the new device.

1. Tap the edit icon next to the authenticator app you want to change.

2. Read the notes carefully before tapping [Continue]. Please note that withdrawals and P2P transactions will be disabled for 24 hours after changing your authenticator.

3. Complete 2FA to continue.

4. You’ll see a QR code and a 16-digit code. Scan the QR code with your new authenticator or enter the 16-digit code manually. Please make sure you’ve completed this step in your new authenticator before tapping [Next].

5. Enter the 6-digit code from the new authenticator and tap [Submit].

6. Your authenticator has changed. Please note that withdrawals and P2P transactions will be disabled for 24 hours after changing your authenticator.
