What is the verification code issued by Ping An Bank for?

China Ping An is a means to ensure its own operation and personal information security.

Now that the network is developed, personal information is easy to leak. Once you enter China Ping 'an Gold Butler app, your ID card, bank card, home address, contact information, work unit, insurance purchased and so on are all clear. You can operate that set of money by yourself.

Don't you need a password to buy things, such as Alipay, WeChat payment and bank card payment? Don't you have to be verified first? Don't you log in? This is all for the safety of your property.
