First of all @bcworkz thanks for your answer!

I found a solution that does the trick for the moment:

add_action( 'init', 'myPasswordInit' );
function myPasswordInit() {
	if(strpos($_SERVER["REQUEST_URI"], 'parent-page') !== false) {
		// i check if the cookie of the password protected page is there
		// trigger password protection
		if(!isset($_COOKIE[ 'wp-postpass_' . COOKIEHASH ])) {
			//if the password it's not set, i redirect to the parent page
			wp_redirect( home_url( '/parent-page/' ) );
		}
	}
}

Not working so good because it get’s sometimes confused with the wp-admin user cookie, but for my pourpouse was more than enough!

Okay, now i see what i’m doing wrong. I dont have the Social Meta feature enabled, so now i can see this options. Thank u so much for the reply 🙂

Thanks! I will check it now, thank u for the usefull help 🙂
