Plugin For Society Members Login

I am looking for a plugin that can enable members of a given savings society to login and view their information related to their savings, loan payments / balances and statements wherever they are.

The information is currently managed locally and someone will be assigned t enter the information on a regular basis. What I need is to know the software / plugin that I can integrate in the website to display that data which can be accessed by only logged in members and only their accounts.
