Hi All -
I have a custom application, built in Web AppBuilder Developer, deployed to a standalone server running on an Amazon Web Services EC2 instance. I would like to add an ArcGIS Online (AGOL) sign in screen that displays when the web application loads (preferably prior to the web application's loading page displays).
The basic idea is that I would like to authenticate users to the web application, using their AGOL accounts, prior to them accessing the entire application. This authentication would also "pass through" to any non-public AGOL content that is accessed by the web application.
Is it possible to add a sign in feature to the web application?
