Do I need an ArcGIS Identity to use VertiGIS Studio Access Control Designer?

An ArcGIS Identity with the ability to create content within Portal for ArcGIS or ArcGIS Online is required to sign in to VertiGIS Studio Access Control Designer, to enable access to save permissions, but it’s not required for users. The users and groups that permissions can be configured for come from the security model that you use to secure ArcGIS Server: Federated Security, Windows Integrated Security or Token Security.
