My website is controlled by password and/or IP address. I have a client who has a password protected website and that client has about 15,000 users. I would like to be able to allow all users of that client's site to be able to enter my website once they have logged into the client's site. I do not know the client's users and do not want to have to create thousands of passwords or IP accounts for those users.
Is it possible to allow entry for all users logged into another website into my website. That is, anyone who logs into the client's website can click on a link that would allow them entry to my website. All of the users of the client's website have very different and unique IP address as they login from around the world.
