# Add an organization administrator

> Step-by-step guide for organization administrators to add or remove other administrators in Cognite Data Fusion (CDF).

Organization administrators have full control over organization-level settings, including registering applications and managing access. Assign this role carefully; at least one administrator must remain active at all times. For more information on organization administrators, see [Organizations](/api-reference/concepts/20230101/organizations).

## Prerequisites

* You must be an existing organization administrator to add or remove other administrators.
* The users you want to add must have signed in to the organization at least once.

<Note>
  If your organization has no administrators yet, contact your Cognite representative and share the user IDs of the users who should become organization administrators. To find a user ID, select the username in the bottom-left corner of the sidebar and select <span class="ui-element">Manage account</span>.
</Note>
