title: Removing "Password protected" option from custom post type
body: <p>Is it possible to remove "password protected" option from the visibility using a hook? </p>
  
  <p>I found the following hook, but it seems I can only check the status of the post.</p>
  
  <pre><code>add_action( 'transition_post_status', 'my_function_to_check_status', 10, 3 );
  </code></pre>
