# Create an ACC registration key

Set up an Agent Client Collector \(ACC\) by creating an agent registration key to identify and authenticate agents that are enabled to send data to the collector. The key helps promote the security and integrity of the data collected from the system.

## Before you begin

Role required: sn\_dex.admin

## About this task

**Important:** By default, the registration key you generate expires in 90 days. Update the **sn\_agent.registration\_key\_validity.days** property to change the validity duration.

## Procedure

1.  Navigate to **All** > **Agent Client Collector** > **Deployment** > **Agent Registration Key**.

2.  Select **New**.

3.  In the **Name** field, enter a descriptive name for the registration key.

4.  To receive notifications when a registration key is soon to expire, select a group with a valid email address in the **Ownership Group** field.

    When keys are deleted by the **Cleanup Agent Registration Keys** scheduled job, the indicated group receives an email notification.

5.  Select **Submit**.
