I was working on a web project where we are using 3 platforms together. Ghost for blogging, Discourse for forum and a custom meteor app. What I want is, that user registers through one of these platforms and is then able to log in on another platforms without signing up.
Will oAuth be useful here ? If yes, how?
Is there any other way, I can accomplish this?
I see that oAuth is supported by ghost https://github.com/TryGhost/Ghost/wiki/How-does-oAuth-work-with-Ghost%3F but I am not sure how is it useful in this scenario.
I have very limited knowledge on this topic, so any educational resources in layman terms that I can read or watch would be a great help.
