I’m researching this for a customer. They have 2 Wordpress sites and 1 site built on C# .NET. They have users that could have accounts in any of the 3 sites. They want to implement SSO so that 1)if a person registers on any site, they’re registered for all three, and 2) if anyone logs in to any site, they’re logged in to all three.
I’m just getting familiar with authorization and authentication and have a trial Auth0 account to experiment with. I see there is an Auth0 Wordpress plugin which should make things easier to get going, and I did get one of their sample ASP.NET apps working in as much as I can login and logout, so I should be able to figure out the .NET side of things. But how do I associate all the users with all three sites?
Any suggestions, directions or resources are greatly appreciated.
