+## Manage user roles
+NetBird has three user roles - `Owner`, `Admin`, and `User`. The roles allow you to control the level of access to the management API of your account.
+
+- `Owner` role - has full access to the account and can manage all aspects of the account. There can be only one account owner in NetBird. Users with the owner role can delete their organization account. See the [Delete NetBird account](/how-to/delete-account) section.
+- `Admin` role - has full access to the account except that administrators can't delete or update the role of the Owner user and delete the organization account.
+- `User` role - has limited access to the account, allowing users to view peers they own and others they can connect to. Users can create personal access tokens for programmatic access.
+
+To manage user roles, proceed to the `Users` tab and click on the user you want to update:

+</p>
+After that, select the desired role from the dropdown:
+<p>
+  <img src="/docs-static/img/how-to-guides/user-update-role.png" alt="high-level-dia" className="imagewrapper"/>
+</p>
+Click the `Save` button to save the changes.
+<Note>
+    Only users with the `Owner` role can assign another user as `Owner`; this action will transfer the `Owner` role to another user, making the current user `Admin`.
