Is there a way to detect if a user is using the same device/browser on a web page e.g. If the user enters the site in the morning with a laptop, the client-side sends a token to the server and if the user enters the site in the evening with the same laptop or device, the client-side must send the same token.
The possibility that comes to mind is saving a token in a cookie and getting it back later, but it is very unsafe.
