Members Section

Hi folks,

I would like to setup a member section of my wordpress website. My thought was to have page that contains a username/password login. Once logged in, the user will be directed to their private page(s) that may or may not have a child page(s)

Users will not need to register, it will be a situation where I will register for them for they are existing clients.

Any thoughts on what plugins are best suited to this?

Thank you!
