class Kernel extends HttpKernel

    protected $middleware = [

        'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
    ];
}

\Modules\Accounts\Routes\public.php

Route::middleware('auth')->group(function () {
    Route::get('account', 'AccountDashboardController@index')->name('account.dashboard.index');

    Route::get('account/profile', 'AccountProfileController@edit')->name('account.profile.edit');
    Route::put('account/profile', 'AccountProfileController@update')->name('account.profile.update');

    Route::get('account/orders', 'AccountOrderController@index')->name('account.orders.index');
    Route::get('account/orders/{id}', 'AccountOrderController@show')->name('account.orders.show');

    Route::get('account/wishlist', 'AccountWishlistController@index')->name('account.wishlist.index');
    Route::delete('account/wishlist/{productId}', 'AccountWishlistController@destroy')->name('account.wishlist.destroy');

    Route::get('account/reviews', 'AccountReviewController@index')->name('account.reviews.index');
});

Where that middleware('auth') came from? there is not anyother kernel files not anyother middleware representations. nothing.....!!

Looking for help!
