Do you need a verification code if it is a mobile phone number?

Why does salted fish need SMS verification every time?

Login and SMS authentication login should choose or set your own mobile phone number. You can change it. After logging in, bind your salted fish to Alipay or Taobao, and then you can choose Alipay or Taobao when logging in. As long as it is the same mobile phone, there is no need for SMS verification.
