    What is your authentication system? If you use ASP.NET Identity it is not possible at least by default.

    Hi alya14,

    You can record the logged-in user ID+SessionID when you log in. You can use Application, Cache, and the database to write a filter to determine whether the current user ID and SessionID match the server's record and the operation performed when it does not match. Release resources when the Session expires or exits the system.

    I hope this article can help you.

    Best Regards,
