Why does China Merchants Bank mobile banking need SMS verification code every time it logs in?

In order to better protect the security of customer accounts, it may be necessary to enter SMS verification code to complete identity verification during the login process of mobile banking and online banking. If you have not made an appointment with China Merchants Bank for a valid mobile phone or the mobile phone has been replaced, please make an appointment or replace it at China Merchants Bank outlets through the professional version or with a valid certificate as soon as possible.
