Using Google reCAPTCHA in your website requires you to get site key and secret key. In this guide, we explain how to get site key and secret key for your site.
Follow the steps below in order to get the keys:
- Go to Google reCAPTCHA admin link from your browser: https://www.google.com/recaptcha/admin
- Log in into your Google account. This will redirect you to the dashboard.
- If you have previously generated keys for a site, then here you can view stats for that site. To add a new site, click on “+” button on top right side.

- Here, you need to provide “Label”, select “reCAPTCHA type” and add “Domains”.

- After, you need to accept the “Terms of Service” then click on “Submit” button to register for a new site.
- Now, you can copy the “Site Key” and “Secret Key” for this new site.

Note: If you use Google reCAPTCHA v3 for a period of time and in the future, it keeps on returning missing-input-response or 0.1 scores. Then, you will probably need to re-create v3 keys.
We also have the premium plugin Login Security Pro with advanced security features for a WordPress site in case you want to check that out.
If you face any issue in generating or using the site and secret keys on your website, then you may contact us. We will respond back to your email as soon as possible.
Friend
I installed your plugin on my website and gave an authentication error with Google Recaptcha version 3.
“unrecognized domain”.
What can it be?
My website is still under construction (maintenance plugin)
Thank you
Hello,
The error “unrecognized domain” is very clear. You have probably added an invalid domain name in the Google reCAPTCHA admin dashboard.
