When working in ArcGIS Pro, you can connect directly to an ArcGIS Server site. This allows you to work with content and, if you have the appropriate credentials, to publish services and perform various administrative tasks. If the server is federated with an ArcGIS Enterprise portal, you provide credentials to the portal's identity store; if the server is not federated, you provide credentials for the server's security store.
Connection types
You can connect to a server in ArcGIS Pro as an administrator, a publisher, or a user to accomplish tasks and work with server content.
The type of connection you can make from ArcGIS Pro to a server depend on whether the server is federated with an ArcGIS Enterprise portal. You can only connect to a federated server from ArcGIS Pro as a user. However, you can connect to a stand-alone server from ArcGIS Pro as a user, as a publisher, or an administrator.

Administrator connections
When you connect to an ArcGIS Server site as an administrator, you can edit server properties such as the configuration store location, and the list of machines participating in the site, as well as manage the site's data stores. You can also publish, add, delete, start, and stop services.
When you connect, you'll be prompted for a user name and password that has administrative privileges to the ArcGIS Server site. This can be either the primary site administrator account that you defined when you created the ArcGIS Server site (in other words, when you first logged in to ArcGIS Server Manager) or another account that has been added to your security store and granted administrative privileges.
Publisher connections
When you connect to an ArcGIS Server site as a publisher, you can publish GIS resources, such as map documents, databases, and service definitions, to your server. You can also configure and publish draft services that reside locally on disk or in the Drafts folder of your connection to the server. Additionally, you can add, delete, start, and stop services. You cannot edit site properties.
When you connect, you'll need to enter a user name and password for a user that has been granted at least publishing privileges by an administrator.
User connections
When you connect to an ArcGIS Server site as a user, you can view and use the services published to the site. However, you cannot edit server or service properties; publish services; or add, delete, start, stop, or pause services.
