How to send a short message to the security center to restore the normal use of the account?

Qq will not recover automatically after being protected, and it needs to be released manually.

How to delete QQ protection:

1. Log in to the number security service area, enter the account number and verification, check the protection reasons, and cancel the security protection by verifying the security protection according to the wizard prompts, such as sending short messages to the mobile phone number bound by QQ Security Center.

2. Log in to QQ Security Center again after cancellation, and select Modify Password to modify QQ password in password management to cancel protection.
