Okay I honestly had a hard time to phrase the question.
That’s why I will just describe what I want to achieve:
I’m using the Realm Web SDK.
When a user opens my app for the first time he should be automatically signed in to mongodb. Maybe through his device ID or some random ID that is generated through a function.
The user should be able to use basic functionality of the app from the go (but restricted of course) and then he can later decide if he wants to create an account.
I saw this approach in free to play games which let you start to play their game without any (visible) registration process and your progress and data is still saved in the database. But if you want to do more specific things like joining a guild you are prompted to make an account.
How would this be possible with Mongodb Realm and the Web SDK?
