Yes, the query is generated by wordpress with this code:

$args = array(
				'post_type'         => 'post',
				'posts_per_page'    => $number,
				'title_length'      => $title_excerpt_words,
				'content_length'    => $excerpt_words,
				'has_password'      => false,
				'order'             => 'DESC',
			);
			if ( is_array( $categories ) && count( $categories ) > 0 ) {
				$args['category__in'] = $categories;
			}

			$post = new WP_Query( $args );

I’m thinking the optimal solution would be adding the index on the post_password field and adjusting the generated query.
