Captcha Types

You can add three types of Captcha: reCaptcha v2, reCaptcha v3, and hCaptcha. 

  1. reCaptcha v2: This version tracks users based on their actions. Such as, it requires users to click on the checkbox “I’m not a robot”. Another way is by presenting some kind of image recognition challenge. 
  2. reCaptcha v3: On the contrary, reCaptcha v3 works on the background. It differentiates a bot and human based on their behavior. It generates a score according to their activities on your site; the higher the score, it’s more likely the user is human. 
  3. hCaptcha: hCaptcha is an alternative option for reCaptcha that differenciate bots from human using advanced machine learning. The main variation between reCaptcha and hCaptcha is that, hCaptcha doesn’t sell user’s data to third party.

After you’ve decided on which version of reCaptcha you want, it’s time to add Site Key and Secret Key

For that, visit this site – Google’s overview page. Now, select the v3 Admin Console option from the top bar.

  • Invisible reCAPTCHA badge: This option validates requests in the background. 
  • reCAPTCHA Android: This option is for androids. It validates requests in your android apps.  

Lastly, click on the Submit button.

In order to add reCaptcha v3, Everest Forms offers different setting options. Just like reCaptcha v2, Site Key and Secret Key is necessary. However, keep in mind that, you need a different Site Key and Secret Key than reCaptcha v2.

The process to create the Keys is the same as reCaptcha v2. The only difference is, you must tick on the reCaptcha v3 radio button on the reCAPTCHA type section.

Select reCaptcha v3

reCaptcha v3 also allows you to set a Threshold Score. The default score is 0.4. If the score is greater than the threshold score, the interaction is good. But, if the score is lesser, it’s possible that the user is a bot. Therefore, the user will not be allowed to submit the form. You can set the score as per your wish.
