Hello, even if you use your signature to spend money, you don't need to enter a password, but there is also a telephone bank to check the password. If you haven't called the bank yet, you can call customer service to open the telephone bank. Some banks do not need to open telephone banking, but only set the inquiry password. You can call customer service and say that you want to set the inquiry password. Customer service can be set up, hoping to help you. You can ask me if you don't understand.
