How to set up a Google reCAPTCHA account and generate API keys


CAPTCHAs (Completely Automated Public Turing Test to Tell Computers and Humans Apart) are designed to identify humans from bots and to protect websites from spam, phishing, and hacker attacks. They use an advanced risk analysis engine and adaptive challenges to keep automated software from connecting with abusive intents to a website. In simple words - you can use CAPTCHA to control who has access over different areas of or your entire site - legitimate visitors or web robots.

Google reCAPTCHA is a free CAPTCHA service that can be integrated into any website or web application. As the name suggests, the service is developed and supported by Google, which makes it extremely popular and widely used. To add reCAPTCHA to your website or web app, you need an API key pair. It consists of a Site Key, intended for invoking reCAPTCHA service on your site or app, and a Secret Key intended for authorizing the communication between your backend and the reCAPTCHA server.

In this tutorial, we are going to guide you on how to set up your Google reCAPTCHA account and acquire the necessary keys.


Setting Up Google reCAPTCHA Account

In order to set up your reCAPTCHA account, all you need is an existing Google account. We trust you have one, however, if you do not, you will be prompted to create a new one during the setup.

To begin, you need to go to Google reCAPTCHA. When you land on the intended page, please click on the "Admin console" button at the top right corner.


Access Google reCAPTCHA Admin Console


Depending on whether you have signed into your Google account, you will be prompted to either select one of your existing accounts, sign up, or create a new account.


Sign in Google Account


As soon as you sign in to your account, you will be automatically presented with the "Register a new site" form.

Within the first "Lebel" field, you have to enter a title, which is only for your reference and will help you quickly recognize this site in the future.

Under the second "reCAPTCHA type" section, you will find two radio buttons presenting each verification type.

Briefly explained, the reCAPTCHA v3 works in the background and does not require your visitors to take any additional actions to be verified. The reCAPTCHA v2, on the other hand, may require particular user interaction based on the selected type:

  • I’m not a robotcheckbox - Validates requests by marking the checkbox.
  • Invisible reCAPTCHA badge - Validates requests in the background.
  • reCAPTCHA android - Validates requests in your android app.

In case you need an in-depth explanation, please refer to Google's official documentation.

Within the following "Domains" section, you need to enter the actual domain name of your WordPress website. Note that you have to insert only the domain name, i.e., "yourdomain.com", excluding any protocol, path, or ports. If needed, you may enter more than one domain name, where each one should be placed on a separate line. Also, you should know that all subdomains associated with your domain name(s) will be automatically included.

Next, please make sure to tick the “Accept the reCAPTCHA Terms of Services” checkbox and then click on the “SUBMIT” button.


Submit Google reCAPTCHA Site Registration


Once this is done, you will be provided with the required “Site Key” and “Secret Key”.
