How does OpenID user validation works?
问题 Well im trying to implement Steam OpenID login to a website but im not quite sure how it's done and how does Steam validate users who are loged in with OpenID. As for now what i have found out is that steam only gives user id back and nothing else so for the rest of things i would have to use API to get other info of the user. But im not quite sure how does the users get validated on the website once someone is loged in via OpenID. Do i need to make a session or set cookie or store user into
