If you cannot login because you’re shown an error message saying “The message history has been encrypted. Please enter the encrypted password first” it is because you have decided to encrypt your message history.
This password can be different from your QQ sign-in password. If you have forgotten it, we won’t be able to help you reset it for security reasons.
As a last resort you can try to locate your QQ International installation path on your computer and look for a folder named after your account’s QQ ID. By deleting its contents you will be able to sign into QQ International again although you’ll lose all historical data and received files.
You can login to QQ International by using the email address provided when you signed up for a QQ account. This email address and the corresponding QQ number/ID are equally valid forms of identification.
Because your email is linked to your QQ number you have the option to use email as your screen name (please refer to this article for further details).
How do you change the email address associated to your QQ account?
When QQ International for Windows is running you must first open the Main Panel then click on your personal picture to open up your Profile, then click on the little icon next to your name.
Please notice that this action will open a website in Chinese where you can easily change your credentials. Check this out if you need help understanding our pages in Mandarin.
