Seeing as we have a limited number of Portal accounts, I don't want users to create their own accounts. Does anyone know if it is possible to disable the "Create an Account" button so users have to request an account?
Yes, you can disable account creation in Portal. Please see this help topic,
Disabling users' ability to create built-in portal accounts—Portal for ArcGIS (10.4.1) | ArcGIS for Server
Hope this helps,
Thank you Derek for the lightning quick response! That worked. I was looking in the Portal Admin Guide that came with the software so I never would have found that.
