How to retrieve hidden property form a relationship model - laravel

Question

i have 3 models: Order, Lancenter and ClientAccount
Lancenters can create Orders.
ClientAccounts stores username and password.
When an order is created, the Lancenter can choose an existant client account or create a new one, so i show up all ClientAccounts related with the current Lancenter.
For security reasons, i don't retrieve the ClientAccount password when a lancenter wants to create a new order.
So, in ClientAccount.php i have this:
protected $hidden = ['password'];
And in Lancenter.php:
public function client_accounts()
{
return $this->hasMany('App\ClientAccount', 'id_lancenter');
}
In LancenterController.php this function retrieves lancenter's client accounts without the password:
public function getClientAccounts()
{
$lancenter = Lancenter::with('client_accounts')->where('id_owner', Auth::id())->first();
return response()->json(['client_accounts' => $lancenter->client_accounts]);
}
The problem is that the created order belongs to a ClientAccount and in this case i need to retrieve also the password of ClientAccount.
So i have in Order.php:
public function client_account()
{
return $this->belongsTo('App\ClientAccount', 'id_client_account');
}
And this function in OrderController.php retrieves new orders:
$orders = Order::with('client_account')->where('status', $status)->get();
return response()->json(['orders' => $orders]);
Obviously, the ClientAccount is retrieved without the password.
I get it by doing a loop to get the ClientAccount of each order in the index function in OrderController, but i supose that there is a cleaner to do it. Hope you can help me.
Update:
this is the loop in OrderController that i'm talking about
public function index($status)
{
$orders = Order->where('status', $status)->get();
foreach($orders as $key => $order) {
$client_account = ClientAccount::find($order->id_client_account)->makeVisible('password')->toArray();
$orders[$key]['client_account'] = $client_account;
}
return response()->json(['orders' => $orders]);
}
