I often receive short messages from Tencent Technology Verification Code.

The mobile phone always receives Tencent verification code for the following reasons:

1, the QQ password has been stolen. It is a good idea to modify the QQ password. You can click Switch to Security Settings, Password Options, and then click the Modify Password button to modify the QQ password.

2.QQ association makes it possible to log in to multiple QQ at the same time on the same mobile phone device. Sometimes, due to the QQ related function, my QQ logs in to other mobile phones, which leads to the mobile phone constantly receiving QQ information verification code.

3. As the phone QQ matches the address book function, you can open the phone QQ, switch to the contact and address book options, click the Settings button in the upper right corner of the interface, then click the Deactivate button in the opened address book settings interface, and click OK in the pop-up extension panel to deactivate the QQ matching address book function.

SMS verification code is an effective verification code system by sending verification codes to mobile phones. Both large websites, especially shopping websites, have the verification code function of SMS, which can ensure the safety of shopping more accurately and safely and verify the correctness of users.

Some authentication code providers provide SMS authentication code service. Each website sends a request to the provider's server through the interface, and the server sends random numbers or letters to the mobile phone, and the provider's server verifies the authentication code uniformly. Before entering the mobile phone number of the registered member in the system, remind the registered member that the entered mobile phone number must belong to the registered member himself, and the mobile phone is beside the registered member at the moment. If you don't have your mobile phone, you need to ask registered members to bring their mobile phones to re-apply.
