To enhance your account security, please follow the step-by-step system prompts to complete the two-factor authentication binding:
Log in to your account and go to the [Security] page.
Under the "Two-Factor Authentication & Payment Password" section, locate "Authenticator app" and click the toggle switch on the right.
The "Google Authenticator" guide window will pop up. Please follow the 3 steps prompted on the screen directly:
Step 1: Use your mobile phone to scan the QR code on the page, or click the [App Store] / [Google Play] button to download and install the Google Authenticator App. Click [Continue] once installed.
Step 2: Open the Google Authenticator App on your phone, scan the QR code on the webpage or manually enter the secret key to add the account into your authenticator App to get the 6-digit dynamic verification code.
We strongly recommend that you save the QR code or the 16-character secret key securely; this is crucial for account recovery if you lost access to your devices or access.
Step 3: Enter the correct 2FA code into the designated input field on the page to complete the final binding and activation.

3. FAQ: Two-Factor Authentication (2FA) Related Questions
Q1: Why does the system prompt "verification code error" after I enter the 6-digit number from my authenticator App?
A: Dynamic verification codes rely strictly on precise time synchronization. Please ensure that your phone's system time (both time zone and local time) is perfectly synchronized with standard network time. If the time is inaccurate, the generated codes will be invalid. After adjusting the time settings, wait for a new code to refresh and try entering it again.
Q2: What should I do if I encounter difficulties downloading the App or scanning the QR code, and cannot complete the setup?
A: If you experience any system lag, unrecognized QR codes, or other technical issues with Google Authenticator, please do not worry. You can try using other TOTP-compatible authenticator apps such as Microsoft Authenticator, Authy, or 1Password. If issues persist, click the permanent green circular button in the bottom right corner of the page to contact Customer Support for real-time assistance, or Submit a Ticket via the bottom right corner. The official technical support team will guide you through the process.
Q3: What should I do if I lose my phone or lose access to my authenticator app?
A: If you lose your device or cannot use the authenticator app, please first check if you have a backup of the 16-digit secret key or the QR code. If you have a backup, you can directly restore your account in the authenticator app. If you do not have a backup, you can log in to the website as usual using your email verification code, and then manually disable the authenticator on the "Security" page using your email verification code (you can also re-bind it in the same location).
