Exactly what I needed

This works with 4.3.1.
The directions are a little confusing.

Pretty much all you have to do is create a ‘parent page’. The parent page is where all the people will enter the password. On the parent page you have to include a snippet of code. On the child page you include the information you want have but you have to make sure to make it private and keep the passwords different from the other child pages.

I love this plugin!!
