Add session check to posts

If you dont want to completely block your users from logging in another good option is to use the "is_within_session_limit" filter to add a session check to any post.

add_action("template_redirect", function() {
    // Array with post IDs
    $posts_to_block = array(1,2);

    // Check if current posts is one to protect
    if (!in_array(get_the_ID(), $posts_to_block) ) {
        return;
    }

    $within_limit = apply_filters("is_within_session_limit", true, wp_get_current_user());
    if (!$within_limit) {

        // If referrer could be determinde redirect there else home url
        $url = wp_get_referer() === false ? home_url() : wp_get_referer();

        wp_safe_redirect($url);
        exit;
    }
});
