Do I need an ArcGIS Identity to use VertiGIS Studio Web 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 Web Designer, to enable access to save and share workflows, but it’s not necessarily required to access VertiGIS Studio Web applications. For ArcGIS Online, the Identity used to access VertiGIS Studio Web Designer does not need to be an organizational account, it can be a free, public account.
