+title: "Manage Omni Clusters with Nautik"
+description: "Use Nautik to view and manage your Omni-managed Talos Linux clusters from macOS, iPhone, or iPad."
+---
+
+[Nautik](https://nautik.io) is a native Kubernetes client for Apple platforms. It has a built-in Talos Omni integration that lets you authenticate and import clusters directly through a browser-based sign-in flow, without manually handling kubeconfig files.
+
+This guide walks you through connecting Nautik to your Omni instance and importing a cluster.
+
+## Prerequisites
+
+Before you begin, ensure you have the following:
+
+- A macOS, iOS, or iPadOS device with [Nautik](https://nautik.io/) installed.
+- An active [Omni](https://www.siderolabs.com/omni-signup) account with at least one cluster created.
+
+## Add a cluster to Nautik
+
+Nautik connects to your Omni instance using a browser-based sign-in flow. Once authenticated, it lists the clusters available to your account so you can import them directly into the app.
+
+To add a cluster:
+
+1. Open Nautik and click **+ Add Cluster**.
+2. Click **Connect with Cloud Provider**.
+![Nautik connect with Cloud Providers](./images/manage-omni-cluster-with-nautik-cloud-provider.png)
+3. Select **Talos Omni** from the list of providers.
+![Nautik Talos Omni selection](./images/manage-omni-cluster-with-nautik-talos-omni.png)
+4. Enter your **Omni URL** and **Email Address**.
+![Enter your Omni information](./images/manage-omni-cluster-with-nautik-omni-instance-info.png)
+5. Click **Sign In With Sidero**. A browser window will open for you to authenticate.
+6. Once authenticated, select your preferred **Auth Type**:
+   - **OpenID Connect**: Short-lived credentials. You will need to re-authenticate when they expire.
+   - **Service Account**: Long-lived token embedded in the kubeconfig. Works immediately after import with no additional login required.
+![Select Auth Type](./images/manage-omni-cluster-with-nautik-auth-type.png)
+7. Click **Import** next to the cluster you want to add.
+![Import the cluster](./images/manage-omni-cluster-with-nautik-import-clusters.png)
+
+Nautik stores your credentials securely in the device keychain. You can choose between **Local Keychain** and **iCloud Keychain** at import time, iCloud Keychain syncs your cluster credentials across your Apple devices automatically.
+
+8. Close the modal and you should see information on your cluster in the Nautik dashboard.

+
+## Remove a cluster from Nautik
+
+If you need to remove a cluster from Nautik, you can do so at any time. Removing a cluster immediately and permanently deletes all stored credentials for that cluster from the device keychain.
+
+To remove a cluster, right-click the cluster name in the cluster picker and select **Delete**.
