## Agent update

Agents require a valid token for authentication and communication with the platform.

{% hint style="info" %}
The token needs to be configured at the agent level during initial installation. Subsequently, agents will autonomously download and update their token from the platform as needed.
{% endhint %}

Manual update can also be performed using the CLI

<pre class="language-bash"><code class="lang-bash"><strong>datasentinel set token eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJleHAiOjE1ODM2OTUyNzcsImlhdCI6MTU3NjM1MTI3MiwiZGF0Y
