ArcGIS Hub is available to anyone with an ArcGIS organizational account. The capabilities available after signing in to Hub are described below.
To sign in to ArcGIS Hub, do one of the following:
- Open your hub site in a browser window and click Sign in on the global navigation bar.
Note:
Global navigation must be enabled. If you have a community account, use this option to sign in. If you are using a browser with an installed ad blocker, you may not see the option to sign in with a social login (Facebook, Google, Apple ID, or GitHub credentials).
- Go to hub.arcgis.com, and click Sign in.
- Sign in to your organization's ArcGIS Online home page. Click the app switcher next to your user profile, and select Hub.
Tip:
Hub sites that do not have a custom domain contain the hub.argis.com or opendata.arcgis.com subdomain in the site's URL (for example, https://mysite-organization.hub.arcgis.com).
ArcGIS Hub user workspace
Once signed in, you can access your ArcGIS Hub user workspace. Click your username, if necessary, and select View workspace to access your user workspace. What you can access in your user workspace depends on how your organization has licensed ArcGIS Hub, the privileges assigned to your account, and how content has been shared.
Your user workspace is organized on multiple tabs where you can view your content and get started with key workflows. You can click an item name to view the item, or click the Manage button 
for an item to open the item's workspace. Click My workspace in the item workspace header to return to your user workspace.
Note:
The Manage and Edit layout buttons are only available on items you can edit.
The following tabs are available in a user workspace:
