In my database I rely on the user.$id but when an annoynomous user creates an account after for instance an purchase on my website. Does it use the same user.$id?
And how does this work if they already have an account create an anonymous user and then login again
TL;DR
Developers are wondering how the `user.$id` works when dealing with anonymous users on their website. They are unsure if the same `user.$id` is used when an anonymous user creates an account after a purchase. They are also confused about the process if a user creates an anonymous account and then logs in again.
