Plugin to restrict certain pages?

Hi all,

I’m currently producing a website for a client and they require a small ‘members’ area. The numbers of members will be very small and almost all data entry (member details, updates etc.) will be done by myself.

I’ve been looking at membership plugins and it seems the majority or too advanced for what I need. I simply need a system that allows me to create a selection of pages that requires a one-time log in to view. Because membership is purchased outside of the website I also need the plugin to only allow admins to make new member accounts

Thank you in advance,

Joe
