How to get this additionally opened window data in to script?  
I scripted a button for an authentication and need to get the verified data in Perspective. I used 'system.perspective.authenticationChallenge'

The actual `authenticationChallenge()` function doesn't return anything but if you set up an [Authentication Challenge Completed Event Script](https://docs.inductiveautomation.com/display/DOC81/Perspective+Session+Event+Scripts#PerspectiveSessionEventScripts-AuthenticationChallengeCompleted), one of the arguments that receives is a `result` argument containing things like the user data (if successfully authenticated).

You could try to set up a waiting thread and wait for the event to save the result to a session prop or something, but the simpler way to get the result you need is probably to split up your logic into several functions in a project library. The first part would do some set up, start the authentication challenge and that's it. Later, the auth challenge event script would call the second part itself.
