Answer: Two-step verification (2FA) is an enhanced verification mechanism provided to ensure account security. When logging in or operating fund-related functions, in addition to entering the password, you are also required to enter a one-time dynamic verification code.
We support two-step verification via Google Authenticator. Here’s how to enable it:
Go to the Security Center page
Click "Turn on two-step verification"
Scan the QR code generated by the system
Enter the verification code to complete the binding
It is recommended that you back up the key or QR code properly so that you can restore the authenticator when you change the device.
