Help finding a plugin?

Hello!

I am making a website for my Boy Scout Troop.

In Boy Scouts, we have a thing called an ISA… it stands for Individual Scout Account.

What I wanna do, is have a page that users can log into, and see their own ISA statement… but have it unique to each user, instead of having all statements for all users to see.

Is there a plugin that can help me do this?

Thanks!
