Error orange border after activating reCAPTCHA v3

If you’ve registered correctly for reCAPTCHA v3 (by following the instructions at reCAPTCHA v3) & it’s working, you should now see the reCAPTCHA Privacy badge displayed at the bottom of every page on your site (not just the pages where you’ve got CF7 forms).

If the reCAPTCHA badge is not showing, this shows that reCAPTCHA v3 is not working on your site.

We experimented a bit and added some code where we lowered the minimum score required for google to distinguish a human from a bot:

function wpcf7_recaptcha_verify_response($is_human, $response_body)
{
$score = isset($response_body[‘score’]) ? $response_body[‘score’] : 0;
error_log(‘wpcf7 score = ‘. $score);
$threshold = 0.2;
$is_human = $threshold < $score;
return $is_human;
}
add_filter(‘wpcf7_recaptcha_verify_response’, ‘wpcf7_recaptcha_verify_response’, 10, 2);

The value 0.2 is of course much lower than the recommended 0.5, but we found that many perfectly human form submissions only reach a score of 0.3. So Google must have sharpened their recaptcha algo since about a week ago. I searched for further proof of this, but rather to no avail.

Best,
