When I was stolen from QQ, I pressed the button in the lower left corner to forget the QQ password. Then there are several ways. I pressed the button to forget what it is, that is, to fill in the parents' information. If you fill in the information correctly, your QQ will come back. You can try it
Don't worry. The security phone is changed to yours. Once the device lock is unlocked, neither he nor others can access the QQ.Only through your mobile phone verification can you log on.If he does not set any qq security problem, it is easy to change the login password.It is recommended to go to the qq security center to learn more about everything
