I have an online game I will charge $9.99 for an unlimited license. I have a WordPress site that uses WooCommerce as the store front.
It's easy for me to add a new product to my list of products, and to embed the online game into WordPress. How do I authenticate the user before enabling them to play the game?
If they pass a URL to a friend, that URL NEEDS to fail. It they pass their username and password to a friend, then play, I WOULD LIKE that also to fail.
