laravel 5认证总是返回false

我已经尝试了一切，我真的不知道我在哪里做错了，但每次我登录，它返回false。下面是在数据库中存储用户的方法:

public function store(CreateUserRequest $request)
    {
        $user = new User();
        $password = str_random(10);
        $password_hash = bcrypt($password);
        $new_user = $user->create([
            'first_name'=>$request->input('first_name'),
            'last_name'=>$request->input('last_name'),
            'email'=>$request->input('email'),
            'fone_number'=>$request->input('fone'),
            'password'=>$password_hash
        ]);
        $new_user->permissions()->create(UserPermission::$default);
        //send email to the user
        Mail::send('admin.emails.auth.new_user',['new_user'=>$new_user,'password'=>$password],function($message) use ($new_user){
            $message->to($new_user->email)
                    ->from('lilgaetan88@gmail.com','Admin Pedagogia')
                    ->subject("your password");
        });
        return redirect()->route('home')->with('Success',"mail sent");
    }

logincontroller

public function postLogin(LoginRequest $request){
        $remember = ($request->has('remember')) ? true : false;
         if(Auth::attempt($request->only(['email','password']),$remember)){
             return redirect()->intended('/home');
        }
           return redirect()->route('login')->with('fail','email or password incorrect');
    }
}

login.blade.php文件:

<form class="login-form" action="{{route('post-login')}}" method="post">
            @if(Session::has('fail'))
                <div class="alert alert-danger">{{'Illuminate'Support'Facades'Session::get('fail')}}</div>
            @endif
            @if ($errors->has())
                <div class="alert alert-danger">
                    @foreach ($errors->all() as $error)
                        {{ $error }}<br/>
                    @endforeach
                </div>
            @endif
        <div class="login-wrap">
            <p class="login-img"><i class="fa fa-lock"> Login Page</i></p>
            <div class="input-group">
                <span class="input-group-addon"><i class="fa fa-envelope"></i></span>
                <input type="text" name="email" class="form-control" placeholder="E-mail" autofocus>
            </div>
            <div class="input-group">
                <span class="input-group-addon"><i class="fa fa-key"></i></span>
                <input type="password" name="password" class="form-control" placeholder="Password">
            </div>
            <label class="checkbox">
                <input type="checkbox" name="remember"> Se souvenir de moi
                <span class="pull-right "> <a href="#"> Mot de Passe Oublie?</a></span>
            </label>
            {!!Form::token()!!}
            <button class="btn btn-primary  btn-block" type="submit">Login</button>
        </div>
    </form>

当i dd(Hash::check($pssowrd，$new_user->password))时，它总是返回true，这意味着哈希密码是正确的，但身份验证仍然返回false
