3. Click the "OK" button to turn it on. When logging in to the software, you will need to pass the login double authentication. <mark style="color:red;">Note: Please ensure that your current mobile phone number can receive text messages normally, to prevent the failure of double verification due to the failure to receive text messages!</mark>

4. Click the "Bind" button and add "Verifier". Here, we recommend using "Google Verifier" or "Microsoft Verifier". Use the verifier to scan the QR code below or copy the key to add. After scanning or adding the key successfully, click "Next" to fill in the "Mobile Verification Code" and "Verifier Verification Code", and click the "Bind" button to bind the verifier.
