Log out of Wordpress password protected pages when browser closes

Question

I want cookies for password protected pages in Wordpress to expire when the browser window closes. I've tried the following in my functions.php file with no luck:

function custom_password_cookie_expiry( $expires ) {
    return 0;  // Make it a session cookie
}
add_filter( 'post_password_expires', 'custom_password_cookie_expiry' );

Any help would be greatly appreciated

This problem had been solved here. Please see the link:

function wpse_191369_post_password_expires() {
    return time() + 10; // Expire in 10 seconds
}

add_filter( 'post_password_expires', 'wpse_191369_post_password_expires' );
