    Hey guys, We would like to create a desktop app where clients can login using a specific name and password (Given by us), that will grant them access to already built softwares. They will only be able to see/have access to their software which we grant them access to, via the admin login. Within time we will continue to build and add software to this app and we would like the process to be as smooth as possible and generate the most accurate results. All the coding will operate behind the scenes and the result will produce a spreadsheet with their data which they can download/extract.
