Exclude Password Protected Posts from Related Posts in single.php

Hello, I’m using some custom code based on a snippet found over at WPBeginner to display related posts by category in a 3×3 thumbnail grid at the end of a single post.

I have noticed that password protected posts (which I have hidden everywhere via functions.php) do appear in related posts for their respective categories.

Is there a way to tweak my code (below) in order to filter these out?

Thanks!

<?php $orig_post = $post;
				global $post;
				$categories = get_the_category($post->ID);
				if ($categories) {
				$category_ids = array();
				foreach($categories as $individual_category) $category_ids[] = $individual_category->term_id;
				$args=array(
				'category__in' => $category_ids,
				'post__not_in' => array($post->ID),
				'posts_per_page'=> 6, // Number of related posts that will be shown.
				'caller_get_posts'=>1
				);
				$my_query = new wp_query( $args );
				if( $my_query->have_posts() ) {
				echo '<div id="related_posts"><h3>';
				_e ('Similar photos', 'site5framework');
				echo '</h3><h5><ul class="img-list">';
				while( $my_query->have_posts() ) {
				$my_query->the_post();?>
				<li><a href="<? the_permalink()?>" rel="bookmark" /><img src="<?php the_post_thumbnail_url( 'standard-thumb' );?>"><span class="text-content"><span><?php the_title(); ?></span></span></a></li>

				<?
				}
				echo '</ul></h5></div>';
				}
				}
				$post = $orig_post;
				wp_reset_query(); ?>
