[FIXED] Admin only - Anonymous Authentication - Firebase - Android

Issue

I am trying to add anonymous authentication to my app using Firebase. But this error keeps happening:

alt="enter image description here" />

This is my code:

firebaseAuth.signInAnonymously()
    .addOnCompleteListener(task -> {
        if (task.isSuccessful()) {
            // Sign in success, update UI with the signed-in user's information
            FirebaseUser user = firebaseAuth.getCurrentUser();
            updateUI(user);
        } else {
            // If sign in fails, display a message to the user.
            Toast.makeText(AnonymousLoginActivity.this, task.getException().getMessage(),
                    Toast.LENGTH_SHORT).show();
            updateUI(null);
        }
    });

How can I fix this?

Solution

Enable Anonymous login in Firebase.

Head to Firebase console and toggle the switch for Anonymous login.
