Why do I need to enter SMS verification code to log in to mobile phone wing payment?

It is easy to log in to the mobile phone wing to pay and enter the SMS verification code. The reasons are as follows: 1. In order to ensure the security of the account, when logging in to the cashier for the first time, you will be asked to enter the SMS verification code issued by the system for identity verification. After verification, the system will associate the binding account, mobile phone and mobile phone card; 2. In the future, if you change your mobile phone or mobile phone card and log in to Alipay cashier, you need to enter SMS verification code for identity confirmation; 3. If you still use the original mobile phone and the original mobile phone card to log in, you don't need to enter the SMS verification code. Tips: SMS verification code is sent to the mobile phone corresponding to the account. If the merchant uses non-local login, he needs to check the short message on the mobile phone corresponding to the account number and fill in the verification code manually.
