If you have set up ID protection before, simply go to https://account.qq.com/cgi-bin/en/index and follow the link to retrieve your password.
If you forgot your answers to the ID protection questions or have never set it up, you’ll have to verify your identity first and then reset your QQ password and set up ID protection. The verification page is in Chinese as the corporate level security department handles all user ID/password related issues for security purposes.
Step 1: Enter your QQ ID and verification code
Step 2: Receive an authentication code either in the email or via mobile text message (China mobile number only).
Step 3: When you receive the authentication code, fill out the form below.
Step 4: Check the result of your request in 4 hours.
If you can’t retrieve your password this way, you’ll have to create a new account unfortunately. We understand the inconvenience this may cause, therefore we urge you to set up ID protection as soon as you can. To create a new account, go to – http://reg.imqq.com/
