I am creating a payment gateway in ASP.NET Core 6 MVC and need to prevent users from accessing the same screen on different tabs or browsers without using session or tempdata. How can I validate the screen?
It is reasonable to expect that the system should not allow a user to open the same screen with the same login on a different tab or another browser. If a user logs in with another browser or tab, the existing browser login should be logged out automatically to ensure the security of the user's account and prevent unauthorized access.
