How to use hCaptcha on your Child Sites

There is a pretty new captcha service and it is called hCaptcha. Even better is that hCaptcha is a drop-in replacement for reCaptcha and making the change on a site is very fast and easy to do, also hCaptcha is free to use. The service is privacy-centric and you can track the number of times that hCaptcha has been used to protect your site.

In order to be able to use hCaptcha on your child site, you will need to sign up for an account. Once you have created an account you can then view the site key and account secret for your site.

To be able to use hCaptcha on your child sites you will need to install the hCaptcha plugin.

To add the site key and secret key you will need to go to;

The hCaptcha plugin only creates 25 options which is a pretty minimal number, so it will not add a lot of database bloat to the options database table on your sites.

The hCaptcha service is very easy to use a very viable alternative in having to use reCaptcha for blocking bots on your child sites.
