In order to prevent QQ from being stolen, if someone changes my secret security question and password after I bind my mobile phone, will there be SMS notification?

There is a password, but there is no notice in the secret report. After your QQ password is changed, you will receive a short message saying that your QQ number password has been changed to: XXXXX. Please delete this message in time. If my answer can help you, please click "adopt as satisfactory answer", thank you!
