I didn't know that the app sent me a short message verification code. What happened when I didn't have this app?

Text me to pay the verification code, but I didn't buy anything. Maybe someone else is using your Tenpay to spend money online, but this happened without your knowledge. It is recommended to modify the login password and payment password immediately. Tenpay had better open the second verification of login password, and the double protection is safer. You should pay more attention to the arbitrary number software used by scammers, showing the telephone numbers of banks, public security and so on. You should call the bank phone number told on the bank card directly, and don't inquire easily.
