Do you need a creator license for every person you want to fill out a secured Survey123 in ArcGIS Enterprise? That is, if I create a survey with a Creator license, and share it with a group (so only group members can fill it out), does every member of the group need a creator or field worker license to fill out the survey? Will viewer user roles not work? What about if the survey is shared publicly?
Everyone that is going to fill out the secure survey must have a Field Worker, Creator, or GIS Professional license. The viewer role will not work unless the survey is public, at least that was the case the last time I tried using ArcGIS Enterprise 10.8.
I created an ArcGIS Idea asking Esri to treat a survey or feature service shared with the organization similar to how it is with a public survey or feature service, except the public cannot access it. Unfortunately, the idea never gained any traction.
Hmm, that is disappointing. It seems crazy that you have a purchase an account for anyone you want to fill out a survey as an authorized user. And according to https://www.esri.com/en-us/arcgis/products/user-types/explore/field-worker, field workers are dependent types which means at minimum you need to purchase a Creator license for anyone needing to fill out a simple survey. It gets expensive quickly. At least they could make field worker a separate and lower cost item for these kinds of workflows.
Your organization only needs one Creator license to be the admin and the rest of the accounts can be Viewer, Field Worker, or Editor licenses. Each person filling out the secure survey would need a Field Worker license which is $350/user/year according to this page on Esri's website https://www.esri.com/en-us/arcgis/products/arcgis-online/buy . Long ago I was told if you need to purchase additional named users the user type pricing for ArcGIS Enterprise is the same as ArcGIS Online.
Personally, I wish they would combine the Viewer and Editor user types into one user type and add the ability to fill out Survey123 surveys through the web interface to that new user type.
