Google reCAPTCHA

1 min read

This section helps you block bots from spamming your website’s form. It uses a tool from Google to check if a real person is trying to submit the form.

Enable reCAPTCHA on Signup

  • There is a switch labeled “Enable reCAPTCHA” to control this feature.

reCAPTCHA Version

You can choose between two versions of this method:

recaptcha version
  • v2: Usually shows the familiar “I’m not a robot” checkbox.
  • v3: Works silently in the background without bothering your users unless it detects suspicious behavior.

Enter Your Keys (Site Key & Secret Key)

To make these features work, you need two special codes from Google.

reCAPTCHA site key
  • Site Key: This is a public code that goes into your website’s form.
  • Secret Key: This is a private code that stays on your server (in the plugin settings) to verify the check.

How to fill this out:

  1. You will need to get these keys for free from the Google reCAPTCHA website.
  2. Once you have them, copy and paste the “Site Key” into the first box.
  3. Copy and paste the “Secret Key” into the second box.

reCAPTCHA verification failed

verification failed
  • Use this box to change the message people see when they fail the security check. This message appears if someone gets the puzzle wrong or if the system thinks they are a robot. A default message is pre-filled in the text box, but you can overwrite it with your own custom text.

Can not connect to server

cannot connect to server
  • Use this box to write a message for when the security check doesn’t work. This error might show up if your internet is down or if a security setting is stopping the connection. There is already a default message here, but you can change it.

reCAPTCHA Field Title

  • This setting allows you to change the text label that appears above the checkbox on your form. The default text is already set. You can change it too.

reCAPTCHA Theme

  • You can select Light or Dark theme based on your preferences

reCAPTCHA Size

  • You can select Normal or Compact size based on your preference

No-Conflict Mode

no conflict mode
  • Enable No-Conflict Mode to prevent conflict from other themes or plugins and ensure your system runs smoothly.

WooCommerce Registration

If you are running an online store, enable this feature to secure your customer signup process.

WooCommerce enable reCAPTCHA

Enable reCAPTCHA on Signup

This adds a security verification to the registration page during checkout, preventing automated bots from creating fraudulent customer accounts.

Note: Once you are happy with your settings, scroll to the bottom and click the blue button that says Save Changes. If you made a mistake and want to go back to how things were before you started editing, click Discard Changes
