The Web App allows users to access your app via a web browser on any standard Windows/Mac desktop or laptop.
There are two fields:
Enable Web App: Checking this box will enable your Web App.
Access Code: Text entered into this field will be used as a password needed to access the Web version of your app. This setting is optional and may be left blank.
A few other things to note are:
1 ) Access models applied to your app will not apply to the Web App.
2 ) Any content posted to specific groups or users will not be viewable via the Web App. This includes private messages.
