The simplest method is to create a form that has a field with a name that does not conflict with any WP reserved words

<form ....>
  <input name="post_passcode"  .....>
</form>

This is just the basics, of course you should also add a nonce field as well as sanitizing the input.

add_action('init', 'test_form_passcode');
function test_form_passcode() {
  if (!isset($_POST['post_passcode'])) {
    return;
  }
  // sanitize
  // WP_Query
  // If results, loop, get post permalink
  wp_redirect($post_permalink);
}
