ConvertFlow's form elements support adding a required reCAPTCHA checkbox.

To do this, first add the reCAPTCHA v2 integration to ConvertFlow from Settings > Integrations.

To get the reCAPTCHA v2 site key, you'll need to add a "site" in the reCAPTCHA admin console.

Then, click the settings icon.

Next, click to get your v2 site key.

Copy the site key.

Then, add your domain name and any ConvertFlow landing page domains to reCAPTCHA's domain list.

Save your changes and then back to ConvertFlow!

Paste your reCAPTCHA v2 site key and confirm.

Now, when you're customizing your form elements, you'll see the option to require reCAPTCHA.
