# Enable CAPTCHA for customer registration

Reduce the risk of requests by malicious bots by enabling CAPTCHA for customer registration.

The **sn\_customerservice.captchaEnabled** system property determines if CAPTCHA validation is enabled or disabled for customer registration on the Customer Service Management Portal.

Set the system property **sn\_customerservice.captchaEnabled** to **true** to enable CAPTCHA validation. If the property isn’t on the System Properties \[sys\_properties\] table, the default value is **true**.
