# Implement Unmanaged Authentication

> Use a Kubernetes API endpoint for unmanaged authentication

## Overview

To use unmanaged authentication, connect to the following API endpoint:

```text theme={"system"}
https://api.<Org ID>-<Cluster Hash>.k8s.<Zone>.coreweave.com
```

* `<Org ID>` is the Org ID on the [Settings page](https://console.coreweave.com/account/settings) in Cloud Console.

* `<Cluster Hash>` is the unique identifier for your cluster's endpoint.

  You can find it:

  * In the Overview section of your cluster's details in the Cloud Console.
  * In the `apiServerEndpoint` field under the JSON tab of the cluster details.

* `<Zone>` is the deployment Zone for your cluster, in lowercase (for example, `us-east-04a`).

## Create an unmanaged authentication endpoint

Add `api.` to the beginning of your cluster's API server endpoint. For example, if your API server endpoint is:

```text theme={"system"}
abc123-abcd1234.k8s.us-east-04a.coreweave.com
```

The resulting unmanaged authentication endpoint is:

```text theme={"system"}
api.abc123-abcd1234.k8s.us-east-04a.coreweave.com
```

<Warning>
  **Deprecation notice**

  CKS clusters previously offered an unmanaged authentication endpoint at `https://api.<orgId>-<clusterName>.k8s.<zone>.coreweave.com`. Endpoints that use the **Cluster Name** instead of the **Cluster Hash** are deprecated.
</Warning>

### Authentication methods

You can authenticate with this endpoint using:

* Kubernetes service account tokens
* OIDC access tokens
* Webhook authentication

This endpoint does not support the API access tokens in the kubeconfig files downloaded from CoreWeave Cloud Console.
