Adding reCAPTCHA allows you to use human verification technology in your forms, which can decrease the number of spam submissions you receive.
Generating reCAPTCHA Keys in Google
To get started, you’ll need to log into your WordPress site and go to WPForms » Settings. Then, click on the CAPTCHA tab. To configure Google reCAPTCHA, select the reCAPTCHA option. Next, you’ll need to set up reCAPTCHA in your Google account to generate the required keys. To start this setup process, you’ll need to open Google’s reCAPTCHA admin console.
Adding reCAPTCHA to a Form. Now that you’ve set up your reCAPTCHA keys, you’ll be able to add reCAPTCHA to any of your WPForms. To do this, go ahead and create a new form or edit an existing form. After you’ve opened the form builder, look under the Standard Fields section and click on the reCAPTCHA field.
Alternatively, you can always enable reCAPTCHA by going to Settings » Spam Protection and Security in the form builder.
