 * **Add multiple owners**: If an organization only has one owner, the organization's projects can become inaccessible if the owner is unreachable. To ensure that no one will lose access to a project, we recommend that at least two people within each organization have the owner role.
 * **Use teams**: Teams allow you to manage permissions, code ownership, and notifications for groups of people. If you use an identity provider (IdP) for authentication, we highly recommend managing team membership through your IdP. See [AUTOTITLE](/enterprise-onboarding/setting-up-organizations-and-teams/creating-teams).

Deleting an organization account permanently removes all repositories, forks of private repositories, wikis, issues, pull requests, and project or organization pages. Repository configuration settings cannot be restored.
