I am making a script that show popup only one time , then it will never show again on that device..
How is it possible to do this?
I have already tried by using cookies, but these can be deleted by the user and so the effect is limited.
Another question is what is wholly unique per device, IP Address or MAC Address?
The only way is a cookie. There’s nothing 100% uniquely identifiable about a machine that you have access to in an HTTP request. Yes, cookies may be deleted by the user. This is deliberate, live with it.
