What is your alls suggestion? What is the best/easiest way to authenticate users accross multiple unrelated websites? i.e. If a user logs into website1, www.website1.com, which has a link to www.website2.com and both websites require login, how do I get website2 to authenticate the user?
These are two unrelated websites.
I searched for single sign-on but get very complicated results. Any help is appreciated.
