The bank card has opened Alipay, but what if the SMS verification code is leaked?

It depends on the nature of the leaked verification code, including the verification code for changing the login password, the verification code for changing the payment password, the verification code for payment, the verification code for binding the bank card, and the verification code for binding or replacing the mobile phone.

It also depends on whether it is the verification code issued when you operate. If so, it doesn't matter, because the verification code is one-time. When someone else operates again, it needs the verification code he sent during the operation to be effective.
