Why do I have to send a text message to receive the verification code before I can log in after I open a QQ member?

QQ members have a security privilege "mobile phone notification with abnormal number".

Permission description:

The mobile phone notification function of abnormal numbers is one of the number security protection measures for QQ members, so that QQ members can monitor the number security anytime and anywhere! When your QQ number has the following abnormal conditions, the system will send an abnormal prompt to your mobile phone, and then you can judge whether it belongs to your personal operation according to the contents of the abnormal prompt. If not, you need to lock the number and apply for password protection and other protection operations. Prompted abnormal information includes the following contents:

QQ number password is abnormally modified;

Exception in querying account balance of QQ number;

QQ number was reported to be sending spam and harassing short messages abnormally;

Delete friends when QQ number is abnormal;

QQ number login exception;

note:

Normal password modification will not send a notice to the user's secret mobile phone.

When the system sends you abnormal prompt information, you may not receive abnormal prompt information in time due to network reasons and problems of your mobile phone terminal (such as power off/short message storage is full, etc.). ). Please try to make sure the mobile phone network and SMS reception are smooth.

The situation you described shows that your number has been abnormal, your password may have been leaked, and it may be used by others to send advertisements or scam messages without your knowledge. Please kill Trojan horse immediately and change the password.

After changing the password, your number will return to normal, so don't be too nervous.

Change the password to enter QQ Security Center: → Change the password.
