Add Custom function to Auth Class Laravel (Extends Guard Class) - php

Question

I had modified a vendor file of Laravel placed at
/vendor/laravel/framework/src/Illuminate/Auth/Guard.php
but it will be overwritten upon updating Laravel.
I'm looking for a way to put the code somewhere in my /app to prevent the overwrite.
The function modified is
public function UpdateSession() {
$this->session->set('type', $type); //==> Set Client Type
}
Also there's a new function on the file:
public function type() {
return $this->session->get('type'); //==> Get Client Type
}
Codes above are called in many places in my application.
Any idea?

Steps:
1- create myGuard.php
class myGuard extends Guard
{
public function login(Authenticatable $user, $remember = false)
{
$this->updateSession($user->getAuthIdentifier(), $user->type);
if ($remember) {
$this->createRememberTokenIfDoesntExist($user);
$this->queueRecallerCookie($user);
}
$this->fireLoginEvent($user, $remember);
$this->setUser($user);
}
protected function updateSession($id, $type = null)
{
$this->session->set($this->getName(), $id);
$this->session->set('type', $type);
$this->session->migrate(true);
}
public function type()
{
return $this->session->get('type');
}
}
2- in AppServiceProvider or new service provider or routes.php:
public function boot()
{
Auth::extend(
'customAuth',
function ($app) {
$model = $app['config']['auth.model'];
$provider = new EloquentUserProvider($app['hash'], $model);
return new myGuard($provider, App::make('session.store'));
}
);
}
3- in config/auth.php
'driver' => 'customAuth',
4- now you can use this
Auth::type();

This doesn't look like you need to update the Guard at all. As far as I can see you are only trying to retrieve data from the session. And that's definitely no business for the Guard itself.
You have multiple ways of accessing the session yourself:
// via Session-Facade
$type = Session::get('type');
Session::put('type', $type);
// via Laravels helper function
$type = session('type'); // get
session()->put('type', $type); // set
session(['type' => $type']); // alternative
