Pay attention to maintaining the system at ordinary times to ensure safety. In addition, try not to enter the password directly with the keyboard. Now, basically, you can find a small pattern of the keyboard next to the password input field. After clicking, a small keyboard will pop up, and click with the mouse to enter the password, so as to ensure that your password will not be recorded by hacker programs. If it is really stolen, call the futures company in time and ask them to initialize the password, then you can log in and modify it. In particular, don't use the default password given by the futures company, which is easy to be tried by other customers.
