+The only requirement is that your new class MUST extend the provided `UserModel`. Shield has a CLI command to quickly create a custom `MyUserModel` by running the following command in terminal:

+```console
+php spark shield:model MyUserModel

+You should set `Config\Auth::$userProvider` as follows:
 
 ```php
-public $userProvider = 'CodeIgniter\Shield\Models\UserModel';
+public $userProvider = \App\Models\MyUserModel::class;
