Navigate to the Google reCAPTCHA Admin page (, click the domain you want to use the WordPress reCAPTCHA API keys for.


On the next page click the Keys link, under Adding WordPress reCAPTCHA API to your site. You will then see your Site key, and Secret Key listed, save them for later use. For example, you can copy and paste them into a .txt document.


Log into your WordPress Dashboard

Click Plugins, then click Settings under WP-reCAPTCHA


Enter your Site Key, and Secret Key, then click the Save reCAPTCHA Changes button. You are finished when you see a Settings saved message.
