I'd love if someone could explain if the 'fake email' address that the developer gets from Apple will be the same across all apps from the same developer? Or is there some way for the developer to link a login on one app to the same user on another app from the same developer?
I'm all in favour of increasing user privacy and the general direction that Apple is moving but we've got multiple Apps which allow users to log in via Game Centre, Facebook or Twitch to the same account. This allows them to access their friends, messages and support tickets from any of our Apps. We're able to do this because each of those providers gives us a unique identifier for each user (we only store that id and don't ever store the email address from them). I fear that Apple are going to make this impossible for us to do this going forward which would be a negative experience for our users.
