The Secured Page Content module is a great way to allow certain users to be able to log in and see content that you may not want the general public to see. You can create separate home pages for different groups of users. If you use it with the Secured File Manager module, you can upload documents and images to your Secured Pages that the general public will not be able to see.
My favourite thing about this module:
I really like that it functions the same way as the regular Page Content module. This makes it extremely easy for users to understand.
