title: How to store application ID credentials safely to be accessed by an application to build sql connection string
body: <p>I have a windows forms application built on c#. The app connects to a sql server with a windows application ID to operate.
  The user will not have access to this App ID credentials. They just connect as a remote application with their own windows ID. And the application's back-end connects with the app ID to the DB.</p>
  
  <p>I need a way to safely store the App ID credentials in the server where I host the tool. The Credentials should be easily updated every now and then.</p>
