The ArcGIS portal, also known as the ArcGIS Online portal, is an instance of the portal service hosted in the cloud by Esri that provides geospatial content management functionality. It is used to store, manage, access, and share different types of content. A portal is also where ArcGIS organizations are located. An ArcGIS Online account or ArcGIS Developer account is required to log in and access the portal in order to use tools such as ArcGIS Online, the developer dashboard, ArcGIS Pro, or APIs. The ArcGIS portal includes functionality to support user identity, administration, and authentication.
