Lost your phone or switched to a new one without migrating Google Authenticator? Here's how to regain access. Visit the Binance Official website or Binance Official APP. iPhone users can check the iOS Installation Guide.
If you saved your backup key: Open Google Authenticator on your new phone, add the account using the saved key, and your codes will work immediately. If you have your old phone: Use Google Authenticator's export/transfer feature to migrate accounts to the new device via QR code. If you have neither: On the Binance login page, click "Security verification unavailable?" and follow the 2FA reset process. You'll need to verify your identity through email, selfie with ID, and other security checks. The reset typically takes 24-48 hours.
Prevention tip: Always save the backup key when setting up 2FA. Store it securely offline (written on paper, not in your phone's notes).
Q: Will resetting 2FA put a temporary withdrawal hold on my account?
A: Yes, typically 24-48 hours. This is a security measure to prevent unauthorized withdrawals during the reset window.
