Laravel 5 - creating two tables during registration - authentication

Question

In my database design, I have two tables, People & Auth. The Auth table holds authentication information and the person_id while the People table holds all other information (name, address, etc). There is a one-to-one relationship between the tables as seen in the models below.
The reason I have separated the data into two tables is because in my
application, I will have many people who do not have authentication
capabilities (customers to the user).
App/Auth.php
class Auth extends Model implements AuthenticatableContract, AuthorizableContract, CanResetPasswordContract
{
use Authenticatable, Authorizable, CanResetPassword;
public function person() {
$this->belongsTo('Person');
}
}
App/Person.php
class Person extends Model
{
public function auth() {
$this->hasOne('Auth');
}
}
In my AuthController::create() method, I am attempting to populate both models with the user supplied information like this:
protected function create(Request $request)
{
$person = \App\Person::create($request->all());
$auth = new \App\Auth;
$auth->fill($request->all());
$auth->person_id = $person->id;
$auth->save();
return $person;
}
In my application, I would like to authorize a user and pass a $user object as the authenticated person to subsequent routes. Am I doing this correctly? Is this the best way? There's cookies and bonus points if you can also explain how to retrieve the $user object after authentication...Auth table data is not needed in the $user object.
EDIT
I have changed my config/Auth.php file to reflect the changes as noted in the answers below (thx #user3702268). However, I have now found an error with my controller. In the AuthController::create() method, I am returning my App/Person object and this throws an ErrorException seeing as how App/Person does not implement the Authorizable trait. I do not want my App/Person object to be authorizable, but it is the object that I want returned as the authenticated $user in my views. How? Shall I simply override the postRegister method or is there a more Laravel way?
EDIT 2
I'm now returning the $auth object which uses the authorizable trait. In my views/controllers I'm trying to access the Person using Auth::user()->person but getting Class 'Person' not found errors

You should replace the App\User Class in config/auth.php line 31 the class that contains the username and password:
'model' => App\User::class,
to
'model' => App\Auth::class,
Be sure to encrypt the password before saving by using the bcrypt($request->get('password')) helper or Hash::make($request->get('password')). Then you can authenticate by calling:
Auth::attempt([$request->get('username'), $request->get('password')]);
You can retrieve the authenticated user using this:
Auth::user()
