# Manage access to a namespace
{% hint style="info" %}
Kubernetes role-based access control (RBAC) must be enabled and working before access control will work in Portainer.
{% endhint %}
From the menu select **Namespaces** then select **Manage access** on the same row as the namespace you want to manage.
Select the users/teams who will have access then click **Create access**.
{% hint style="info" %}
Users or groups with cluster-wide roles (such as the Operator role) cannot be assigned to individual namespaces, as their cluster-wide nature applies to all namespaces in the environment.
{% endhint %}
