Customized php widget for every customer

I'd like to add a restricted member area to my homepage. For my idea, every member has to be differentiated. That means that customer A sees/ gets different information through a PHP widget then customer B. (So not the classical membership gold, silver, bronze thing)

The PHP widget grabs the information for every customer from a database on another server.

What I am searching is a restricted area plugin which gives me the power to differentiate every customer and integrate that into my divi homepage.

I'd be more than happy if someone could share his experiences and help me solve this problem!

Thx
