Pixel Streaming and user logins for access

Hello - I have a pixel streaming setup in a network not connected to the internet. I would like to set up a system where the user needs to log in with userid/password. I am able to set true to UseAuthentication, and it brings up the login.html webpage.

How would I setup the userid/password from within the SignalingWebServer structure under modules? I am unable to find any information in the documentation.
