## Description

reCAPTCHA for Jetpack enhances your WordPress site’s security by integrating Google
reCAPTCHA v3—an invisible, score-based spam filter—with Jetpack contact forms, comments,
and WooCommerce registration. Designed for block-based themes (e.g., Full Site Editing),
it uses behavioral scoring to block bots seamlessly. Key features:

 * **Invisible Protection**: Analyzes user behavior (e.g., mouse movements, session
   duration) to assign a score (0.0–1.0) for contact forms, comments, and WooCommerce
   registration.
 * **Customizable Threshold**: Set a score threshold (default 0.5) to balance spam
   blocking and user access for all forms.
 * **Conditional Loading**: Control where reCAPTCHA loads: on all pages, specific
   page types (e.g., front page, single posts), or specific slugs. Improves performance
   by skipping unnecessary pages.
 * **Debug Mode**: Toggle console.log output for debugging purposes; disable for
   production to reduce browser console clutter.
 * **Skip for Logged-in Users** (new in 1.17): New checkbox to bypass reCAPTCHA 
   entirely for any logged-in user (admins, customers, members, etc.). Perfect for
   membership sites where only guests need protection.
 * **Automatic Spam Handling**:
    - Form submissions with scores below the threshold are reliably blocked and 
      moved to the Jetpack Feedback CPT spam folder in the admin interface.
    - Comments with scores below the threshold are automatically moved to the spam
      folder without triggering approval emails.
    - **New in 1.13 / 1.14**: Blocks bot account creation on WooCommerce registration
      form (including the My Account page).
 * **Submission Stats**: Tracks total submissions and logs the last 20 submissions(
   forms, comments, registration) with scores and status (success/spam) in a streamlined
   manner.
 * **Jetpack Integration**: Requires Jetpack for contact form and comment protection,
   fully compatible with block-based forms and Jetpack forums.
 * **Email Enhancements**: Appends reCAPTCHA scores to form submission emails and
   comment notification/moderation emails for transparency.
 * **Admin Feedback**: Displays reCAPTCHA scores to admins on form success pages
   and logs detailed debug info for failed submissions.

Perfect for modern WordPress sites, this plugin provides robust spam prevention 
with insightful analytics, ensuring a seamless user experience while keeping your
forms, comments, and registrations spam-free.

### External Services

This plugin uses Google reCAPTCHA v3, a service provided by Google to verify user
interactions and prevent spam on contact forms, comments, and WooCommerce registration.

 * **Purpose**: Google reCAPTCHA v3 analyzes user behavior to assign a score (0.0–
   1.0) indicating the likelihood of a user being a bot. This score determines whether
   form submissions, comments, or registrations are blocked (moved to spam).
 * **Data Sent**: When a user submits a form, comment, or registers, the plugin 
   sends a reCAPTCHA token to Google’s API (`https://www.google.com/recaptcha/api/
   siteverify`). The request includes only the secret key and response token.
 * **When Data is Sent**: Data is sent to Google’s API on every Jetpack contact 
   form, comment, or WooCommerce registration submission.
 * **Service Provider**: Google LLC.
 * **Terms of Service**: https://www.google.com/recaptcha/about/
 * **Privacy Policy**: https://policies.google.com/privacy

Users must agree to Google’s terms of service when setting up reCAPTCHA keys. No
user consent is required for reCAPTCHA v3, as it operates invisibly without challenges.

     in the settings page.

## FAQ

### Do I need Jetpack for this plugin?

Yes, Jetpack is required for contact form and comment protection.

### How does reCAPTCHA v3 work?

reCAPTCHA v3 runs invisibly, analyzing user behavior to assign a score (0.0–1.0).
Form submissions, comments, or registrations scoring below the threshold (default
0.5) are reliably blocked, with forms moved to the Jetpack Feedback CPT spam folder
and comments flagged as spam.

### Where do blocked form submissions go?

Form submissions failing reCAPTCHA verification are saved in the Jetpack Feedback
CPT with a ‘spam’ status, visible in Jetpack > Feedback > Spam in the admin interface.

### How do I check my site’s reCAPTCHA scores?

Submit a form, comment, or register—then view total submissions, the last 20 submissions(
with scores and spam/success status), and debug logs in Settings > reCAPTCHA for
Jetpack. Detailed analytics are available in the Google reCAPTCHA Admin Console.

### Why do I see “The reCAPTCHA keys format is invalid” error?

This error appears if the Site Key or Secret Key entered in the settings is not 
40 characters long or contains invalid characters (only letters, numbers, hyphens,
and underscores are allowed). Common causes include:
 – Copying only part of a key
or adding extra spaces. – Using keys from reCAPTCHA v2 or another service. To fix
it: 1. Visit [Google reCAPTCHA admin](https://www.google.com/recaptcha/admin/create).
2. Select your reCAPTCHA v3 site or create a new one, ensuring “reCAPTCHA v3” is
chosen. 3. Copy the full 40-character Site Key and Secret Key exactly as provided.
4. Paste them into the settings page and save. 5. Test a form or comment to confirm
the keys work. For help, see Google’s setup guide: [https://developers.google.com/recaptcha/docs/v3](https://developers.google.com/recaptcha/docs/v3).

### Why do my form or comment submissions fail reCAPTCHA verification?

A low reCAPTCHA score (below the threshold, default 0.5) can occur if users auto-
fill forms or comments using browser autofill or password managers, as this mimics
bot behavior. To improve verification success:
 – Fill out forms and comments manually,
avoiding autofill tools. – Check the score and status in the “Last 20 Submissions”
table in Settings > reCAPTCHA for Jetpack. – Adjust the score threshold lower (e.
g., 0.3) if legitimate submissions are frequently blocked. For persistent issues,

## Changelog

#### 1.17

 * **New Feature**: Added “Skip reCAPTCHA for all logged-in users” checkbox under
   Configuration in the settings page.
 * When enabled, any logged-in user (admins, customers, members, etc.) completely
   bypasses reCAPTCHA on Jetpack forms, comments, and WooCommerce registration.
 * Ideal for membership sites where only guests need protection.
 * The new option is fully documented, sanitized, and uses the standard hidden-input
   pattern so it can be turned off reliably.
 * All previous features and fixes from 1.16 remain fully intact and unchanged.

#### 1.16

 * **Major reliability, performance & security improvements**:
    - Hardcoded plugin version constant (eliminates unnecessary disk I/O on every
      page load).
    - Fixed critical JavaScript submit race condition (preventDefault + dispatchEvent
      so Jetpack AJAX and WooCommerce validation still run).
    - Removed WordPress nonces entirely (prevents “Invalid nonce” errors on cached
      sites).
    - Fixed Debug Mode and WooCommerce registration checkboxes so they can actually
      be turned off.
    - Removed background token refresh interval (prevents quota burn on long-open
      tabs).
    - Removed optional remoteip parameter (fixes Cloudflare/proxy false positives
      and GDPR concerns).
    - Added server-level error handling for wp_remote_post failures.
    - Fixed Debug Mode string handling in JavaScript.
    - Fixed settings sub-options visibility on page reload.
    - Updated documentation to accurately reflect reCAPTCHA v3 score range (0.0–
      1.0) and removed IP mention.

   stats, etc.) remain fully intact.

#### 1.15

   on non-Woo sites.

 * Improved key save success message to detail validation checks and guide users
   to test forms/comments.
 * Added warnings about auto-filling forms/comments causing low reCAPTCHA scores,
   with guidance to use manual input, in the form failure message and settings page.
