First, none of the data I am working with is Public. It cannot be shared Public.
I am using Collector for ArcGIS and Survey123 for ArcGIS with AGOL. However, I want to be able to view my AGOL Web Maps in our local Web App Builder. This can only be done by setting up a proxy. But, is another option to use Portal for ArcGIS?
Can Web Maps made in Portal be viewed inside a local Web Map made with the Web App Builder 2.1/3.0 without being prompted for a username and password?
Portal for ArcGIS is installed on a local server machine?
I am thinking there are other reasons to use Portal for ArcGIS over AGOL, any thoughts on why you would use one vs the other?
