I put together an app the other day with the web app builder and when I send the URL to someone it requires them to log on. The content, web map, and app are all shared publically. Also, surprisingly if I create the app using an ESRI template instead of the web app builder I am able to successfully share that app with anyone without requiring login. Is there a step I am missing with the Web App builder that will allow the finished app to be publically viewable.
Thanks
Mark
