Membership /Account Management software?

Hello, I was wondering if anyone can suggest a good program for managing the membership accounts of a website I'm working on.

It must have the ability to setup individual pages that are visible only by specific members, rather than simply allowing all registered members to view a common area. Each member will be assigned an account, and each account will contain confidential and unique info (like a bank account) that must be accessible only by the account holder.

The program itself can serve as a database of member's account information, or can it be interfaced with an external database such as MS Access.

So far, I am leaning towards Account Manager Pro, at siteinteractive.com, mainly because it's the only one I've found that may work. Does anyone have any other suggestions? Thanks.
