# Activating CA

# Activating Continuous Authentication {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
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 AllSystem ApplicationsAll Available ApplicationsAll. {#activate-continuous-authentication__find-plugins-cmd}
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.{#activate-continuous-authentication__p_cb1_nfg_h1c}
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.
