Redpanda offers two methods to manage authentication and authorization in a Kubernetes environment. These options allow administrators to control user access and permissions, ensuring secure communication with the Redpanda cluster.

-   [Configure Authentication for Redpanda in Kubernetes](k-authentication/)

    Use Helm values or the Redpanda resource manifest to enable authentication for Redpanda. This method provides a way to configure authentication during the initial deployment or updates to the cluster configuration.

-   [Manage Users and ACLs with the Redpanda Operator](k-user-controller/)

    Use the User resource to declaratively create and manage users and ACLs as part of a Redpanda deployment. Each User resource is mapped to a user in your Redpanda cluster. The user controller keeps the corresponding user in sync with the User resource.

-   [Manage Roles with the Redpanda Operator](https://docs.redpanda.com/streaming/25.2/manage/kubernetes/security/authorization/k-role-controller/)

    Use the RedpandaRole resource to declaratively create and manage roles as part of a Redpanda deployment. Each RedpandaRole resource defines a set of permissions that can be assigned to multiple users, providing role-based access control (RBAC) for your Redpanda cluster.
