Is it possible to make a Story Map public without the public having to create an account with ArcGIS?
When a user clicks on the link to the story map that I created, the map appears but as soon as the user begins to scroll though the map story a page pops up prompting the user to login or to create an account. Most people do not want to create an account to view the map and the story.
If I embed the map to my webpage will the people viewing the map still need to have an ArcGIS account?
It seems like you while you may have made the map itself public, a portion of the data within it is not - and asking you for credentials to see it. Is there a layer that has security that you weren't aware of?
yes, it is possible to make a Story Map public, embedded as well as just by itself. You need to share all the resources the web map uses (i.e. feature services , basemaps, etc.), the web map itself, and your Story Map application publicly (vs. keeping their status "Private" or shared only with your organization or a group).
