Presentation

Captcha system provided by Google.

Configuration

Configure captcha like LLNG internal captcha but use a “custom captcha module”, set:

  • Captcha module to “::Captcha::ReCaptcha” or “::Captcha::ReCaptcha3” for version 3

  • in Captcha module options, add the following keys

    • dataSiteKey: the key ID given in Google console

    • secretKey: the secret key

    • score (version 3 only): the minimal score. Default to 0.5

Then adapt the “Content-Security-Policy” headers, cspDefault and cspScript should be set to :

Important

Starting from version 2.23.0, authentication form is locked until ReCaptcha is loaded. On slow networks, this avoids getting “Bad captcha” answers, especially with ReCaptcha version 3
