Pro and Portal for ArcGIS

[RenatoSalvaleon]

How can I use Pro with only Portal for ArcGIS as the only portal available for my organization?  The only way I can sign in to Pro is with the Portal web adaptor URL is after I sign in with my personal AGOL account and then add the Portal web adaptor on the portal list. Since our Portal has SSO turned on, as soon as the URL is added, the users get signed in. eOur users cannot have an AGOL account as a matter of organizational policy but they all have acces to our internal portal.

Renato,

If your portal is provisioned with Pro licenses, you can use the "Specify the Licensing portal" procedure when starting Pro, as mentioned in the help topic here:  Review ArcGIS Pro licensing information—ArcGIS Pro | ArcGIS for Professionals -

If that doesn't work, check with your Portal administrator to be sure the portal and your named user are properly provisioned for Pro.
