Firebase do not create user in Unity SDK

Question

It is strange that Firebase can't create user in Unity SDK out of the box. Firebase Console was tuned (anonymous access and email/password access are enabled) and google-service.json was placed in Assets folder of Unity.

However, Firebase still won't create a user. This is the code where it always fails:

auth.SignInAnonymouslyAsync().ContinueWith(task => {
            if (task.IsCompleted && !task.IsCanceled && !task.IsFaulted) {
                Debug.Log("User is now signed in.");
                FirebaseUser newUser = task.Result;
            }
            else if (task.IsFaulted || task.IsCanceled)
            {
                Debug.Log("User signup failed");
            }
        });

Why?

There are possible several reasons:

The app was run in the Editor, rather than on the device
The configuration file is not updated after you add Firebase Auth feature
The password is shorter than 6 chacters
The email address is in invalid form, e.g. abcdef@aaa

The first one is highly likely the reason why.

I have created a tutorial here, which covers the steps to create/login using firebase in Unity, hope this is helpful.

SIR! I swear by the holy potato I am going to buy a cookie. The first one did was the problem . . . The google DOCZ is clearly shitty. (firebase.google.com/docs/unity/setup?authuser=0) The step 6 says Click Switch Platform to select Android as the target platform. Well, I did but it says NOWHERE it would not execute successfully in the Editor. I ran it like thousand times and thousand time I got the message the User was successfully created but I could never see it anywhere unless you as you mentioned to actually deploy on a Device... thanks google wasting 50+ hours
