Restrict certain pages or posts to logged in users
This plugin will allow you to restrict all, none, or certain pages/posts to logged in users only.
In some cases where you are using WordPress as a CMS and only want logged in users to have access to the content or where you want users to register for purposes unknown so that they can see the content, then this plugin is what you are looking for.
Simple admin interface to select all, none, or some of your pages/posts. This now works for posts!

Page Restrict

This plugin used to work great, but with WordPress 4.8+, it fails and the author hasn't provided any recourse. For shame.

Doesn't work. Author(s) refuse to support
