QQ is protected by the security center, so short messages can't be sent out and can't be solved. What happened?

Methods to release QQ protection mode:

1.

Log in to the number security service area, enter the account number and verification, check the reasons for entering the protection mode, and cancel the secret protection by verifying the secret protection according to the wizard prompts, such as sending a short message to the mobile phone number bound in the QQ security center.

2.

Log in to QQ Security Center again after cancellation, and select Modify Password and Change QQ Password in Password Management to cancel the protection mode.

The security risk of QQ account may be due to QQ account logging in at multiple locations at the same time. The reason is that the password of QQ account has been leaked. It is recommended to pay more attention to password security during daily antivirus.
