Android Firebase par JulesFuzeau - page 1

Bonjour pour un projet personnel je souhaiterais faire un sytème de login/register j'ai bien activé la fonction email/mot de passe dans méthodes de connexion dans la console firebase . Or voici mon problème quand j'essaye de créer un profil j'obtiens cette erreur : et mon code :

package com.example.jules.nevone;

import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Patterns;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ProgressBar;
import android.widget.Toast;

import com.google.android.gms.tasks.OnCompleteListener;
import com.google.android.gms.tasks.Task;
import com.google.firebase.auth.AuthResult;
import com.google.firebase.auth.FirebaseAuth;
import com.google.firebase.auth.FirebaseUser;

public class RegisterActivity extends AppCompatActivity {
EditText editTextEmail, editTextPassword, editTextPasswordVerif, editTextPseudo , editTextName;
Button buttonRegister;
ProgressBar progressBar;
private FirebaseAuth mAuth;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_register);

        editTextEmail = (EditText)findViewById(R.id.editText_email_adress);
        editTextName = (EditText)findViewById(R.id.edit_text_name);
        editTextPassword = (EditText)findViewById(R.id.editText_password);
        editTextPasswordVerif = (EditText)findViewById(R.id.editText_password_back);
        editTextPseudo = (EditText)findViewById(R.id.edit_text_pseudo);
        buttonRegister = (Button)findViewById(R.id.button_register);
        progressBar = (ProgressBar)findViewById(R.id.progress_bar);
        mAuth = FirebaseAuth.getInstance();
        buttonRegister.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                register();
            }
        });

    }
    private void register(){
        mAuth.createUserWithEmailAndPassword(editTextEmail.getText().toString(),editTextPassword.getText().toString()).addOnCompleteListener(RegisterActivity.this, new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull Task<AuthResult> task) {
               if(task.isSuccessful()){
                   Toast.makeText(RegisterActivity.this,"Good",Toast.LENGTH_LONG).show();
               }
               else{
                   Toast.makeText(RegisterActivity.this,task.getException().toString(),Toast.LENGTH_LONG).show();
               }
            }
        });
                }


            }
