Authentication Page - UWP app

Question

I am develop a new UWP app, and I want that my first page be an Authentication Page.

But I would like to know if there is any way to manage users. For example, this new application that I am developing will be available in the Microsoft Store (to make the update process easier) but it will be hidden in the store, and I only want 3 to 4 people to be able to access my app so I need an Authentication Page

I want the user to enter a username and password and that this data can be validated, that is, check if they have access to my application. And if so, they can enter the application.

I do not know if I could explain it correctly.

Answer 1

You can limit the user who can download the app by email id. See the links below

Set app pricing and availability

How ever you can create a login page if you want. store the details in a database(SQLite or LocalStorage) compare the details entered with the stored details. if they match go to first page or else ask for re-enter or exit the app.
