Why do you have to receive a verification code to answer the phone when you recharge Taobao?

The account protection function is turned on. When you pay for Taobao shopping, you need to enter SMS verification and telephone verification. This is because the SMS authentication service has been opened, which is a higher-level security protection product based on mobile phone binding. To open this service, you need to pay 0.6 yuan information fee every month, and you can choose to close it. If it is closed successfully, you don't need to accept SMS verification when paying.
