# Activating Continuous Authentication

For activating the Continuous Authentication feature on your instance, install the **Zero Trust - Continuous Authentication** \(`com.snc.zero_trust_continuous_authentication`\) plugin.

## Before you begin

Role required: admin

This plugin enables security administrators to define security policies that require step-up authentication \(MFA\) or re-authentication \(SSO\) within a logged-in session, based on the data the user is accessing and the activities they are performing.

You must install the **Zero Trust - Continuous Authentication** \(`com.snc.zero_trust_continuous_authentication`\) for opting CA which requires a license.

## Procedure

1.  Navigate to **All** > **System Applications** > **All Available Applications** > **All**.

2.  Find the **Zero Trust - Continuous Authentication** \(`com.snc.zero_trust_continuous_authentication`\) plugin using the filter criteria and search bar.

    You can search for the plugin by its name or ID. If you cannot find a plugin, you might have to request it from ServiceNow personnel.

3.  Select **Install** to start the installation process.

    **Note:** When domain separation and delegated admin are enabled in an instance, the administrative user must be in the **global** domain. Otherwise, the following error appears: `Application installation is unavailable because another operation is running: Plugin Activation for <plugin name>.`

    You will see a message after installation is completed. For information about the components installed with a plugin, see [Find components installed with an application](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/platform-administration/find-components.md).
