Have you reviewed guest access in the Visual Analytics administration guide (it is briefly referenced in the linked blog)
https://support.sas.com/documentation/solutions/va/73/en/vaag.pdf
"Guest access is an optional feature that provides anonymous access to a subset of resources and functionality. In guest access, there is no individualized authentication of the requesting user, so there are no requirements for individual user accounts or metadata identities. Instead, all guest users are authenticated as the same service account (the SAS Anonymous Web User). That service account functions as the single surrogate identity for all guest users. All guest users can see what the SAS Anonymous Web User can see, and do what the SAS Anonymous Web User can do."
Good news: We've extended SAS Hackathon registration until Sept. 12, so you still have time to be part of our biggest event yet – our five-year anniversary!
