Provides hCaptcha integration for TYPO3 EXT:form.

hCaptcha is a free to use alternative to Google reCaptcha with a bigger focus on privacy. It supports initiatives like PrivacyPass.

For more information, see the hCaptcha website.

Additionally, hCaptcha provides earnings for solved captchas - that can be donated to the Wikimedia foundation automatically (which is the case for the default settings of this extension).

Quick Setup

hCaptcha is configured with a default key to make the setup as easy as possible. It is recommended to create a custom account for your site with hCaptcha and add your own keys.

Install the extension and activate it
Include the static template in TypoScript
Add a hCaptcha element to a form

  settings {
    publicKey = <your-public-key>
    privateKey = <your-private-key>
  }
}

Environment variables

As an alternative to the TypoScript configuration, you can also use environment variables:

HCAPTCHA_PUBLIC_KEY
HCAPTCHA_PRIVATE_KEY
