This can be accomplished the same way that any WP post field can be changed based on an acf field.

add_filter('acf/save_post', 'post_password_from_acf', 20);
post_password_from_acf($post_id) {
  if (get_post_type($post_id) != 'your-post-type') {
    return;
  }
  $password = get_field('your-acf-field', $post_id);
  $post = get_post($post_id);
  $post->post_password = $password;
  remove_filter('acf/save_post', 'post_password_from_acf', 20);
  wp_update_post($post);
  add_filter('acf/save_post', 'post_password_from_acf', 20);
}
