Hi,
I was thinking about the best way to do the login in my game. I'm using Unity.
My idea was using Unity's System.uniqueDeviceIdentifier and log in with Custom ID.
I read that not all System.uniqueDeviceIdentifier are safe and so, there are the Android ID (taken using Android API). But I can't know if this is really safe.
Than I found also that System.uniqueDeviceIdentifier isn't always safe even if iOS.
So the question: what do you suggest in order to find an unique Identifier per user?
What is the best way?
Thank you.
Best regards,
Andrea
