A short message said let me see the Taobao account.

It should be that you turned on the small secret function, and then your friend logged in with your mobile phone. You don't need to pay the password when you buy with your mobile phone ~ generally, it won't affect your bank card and ID card, but in order to avoid someone paying in this way in the future, I suggest you modify your login password. In addition, if you want to like online shopping, you can go to # Yaya Yaya, which is quite real.
