# Rotate the System API Key

When you register the Trino connection, Immuta generates an API key for you to add to your Immuta access control properties file for API authentication between Starburst (Trino) and Immuta. You can rotate this shared secret to mitigate potential security risks and comply with your organizational policies.

**Required Immuta permission**: `APPLICATION_ADMIN`

{% hint style="warning" %}
**Cluster restart required**

To update your API key in Starburst (Trino), you must shut down your cluster, generate and update the API key, and then restart your cluster. If you do not shut down your cluster, generating a new API key using the endpoint below will cause downtime for your deployment.
{% endhint %}

1. [Disable your Starburst (Trino) cluster](https://docs.starburst.io/starburst-galaxy/cluster-administration/create-edit-and-delete-galaxy-clusters.html#cluster-disable).
2. Navigate to the Trino connection in Immuta.
3. Scroll to the **Policy settings** section, and select **Edit**.
4. Click **Regenerate system API key**. The old API key will be invalidated immediately.
5. Copy the new `immuta.apikey`. Store it in a secure place; the API key will not be shown again.
6. Click **Finish**.
7. [Replace the old `immuta.apikey` value in the Immuta access control properties file](/saas/configuration/integrations/starburst-trino/register-a-trino-connection/customize-the-immuta-trino-plugin.md) with this new key.
8. [Enable your Starburst (Trino) cluster](https://docs.starburst.io/starburst-galaxy/cluster-administration/create-edit-and-delete-galaxy-clusters.html#enable-a-cluster).

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://documentation.immuta.com/saas/configuration/integrations/starburst-trino/register-a-trino-connection/rotate-the-system-api-key.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
