Friends use China UnionPay Express to pay. Why can't I enter the mobile phone verification code? In the past, I used to enter passwords.

I have been using China UnionPay Express. Very convenient. Generally 1000 yuan is convenient and quick to enter the password directly. 1000 yuan or more needs to be bound with the mobile phone verification code to prevent theft or wrong brushing, or 1000 yuan or more is the first time to adapt, please feel free to use it. I am answering. what do you think?
