By default, this header layout doesn’t have Login/Register link. But you can add it manually placing the following code snippet to the functions.php file in the child theme.

add_filter( 'basel_header_configuration', 'basel_custom_header_configuration', 1, 1 );

function basel_custom_header_configuration() {

	return array(
				'container' => array(
					'wrapp-header' => array(
						'logo',
						'main_nav',
						'right-column' => array(
					               'header_links',
							'wishlist',
							'cart',
							'mobile_icon',
						)
					)	
				),
				'secondary-header' => array(
					'container' => array(
						'categories_menu',
						'search_extended',
					)
				)	
	);
}
