# About the host level

> Manage host-level settings including system administrator accounts, authentication, and email configuration in Orchestrator.

The host is the first level in the hierarchy. At this level, you can modify shared platform functionality like system administrator accounts, global authentication settings, global system email settings. You can also edit Orchestrator host settings from the host level. Only system administrators can access the host portal. Host settings apply across all the organizations.

## Host Identity Management hub

The host Identity Management hub displays all the apps in your installation that are integrated with Identity Server. Only system administrators (logged in to the host) can access host portals.

In the host Identity Management hub, you can access host settings for integrated products. By default, these are:

* **Orchestrator**: Opens the Orchestrator host portal, where you can view and manage your tenants and other global Orchestrator settings. To open the Orchestrator host portal, select **Back to Orchestrator**.
* **Management**: Open the host Management portal, where you can manage system administrators and other global settings.
