## Description

VAPTCHA Human Verification is a completely free WordPress human verification plugin.
It helps protect standard WordPress forms from automated abuse while keeping the
original page layout unchanged.

The plugin protects:

 * WordPress login
 * User registration
 * Password reset
 * Comments

Verification opens only when a visitor submits an enabled form. The plugin does 
not add a visible verification button or modify the native WordPress form styling.

#### Free to use

 * The VAPTCHA Human Verification plugin is completely free to download and use.
 * The ready-to-use shared verification unit works immediately after activation 
   at no additional cost.
 * No VAPTCHA account is required for the shared unit.
 * Site owners can optionally connect their own verification unit for independent
   statistics and management.

#### Security by design

The plugin follows WordPress security practices and is designed to keep verification
credentials and form data protected:

 * VKEY is used only by server-side PHP and is never sent to the browser, HTML, 
   JavaScript, REST responses, or browser developer tools.
 * Protected forms use WordPress nonces, input sanitization, and escaped output.
 * Missing, expired, invalid, or forged verification data is rejected.
 * Verification and network failures fail closed instead of accepting the protected
   action.
 * The plugin does not modify WordPress login or comment styles and does not add
   a public credit link.

The plugin includes a ready-to-use shared verification unit, so protection works
immediately after activation. For independent verification statistics and unit management,
create a verification unit at https://www.vaptcha.com/ and enter its VID and VKEY
on the settings page.

### External services

This plugin connects to the VAPTCHA human verification service to protect the WordPress
forms selected by the site administrator.

 * When a protected form is displayed, the browser loads the VAPTCHA SDK from `https://
   c4.vaptcha.com/src/v4.js`.
 * When a visitor submits a protected form and verification starts, the SDK connects
   to VAPTCHA service endpoints to provide human verification. VAPTCHA processes
   the visitor’s IP address, browser and device signals (including the user agent),
   verification-session identifiers, verification results, and the interaction data
   produced within the verification interface, such as operation timing and trajectory
   characteristics.
 * The SDK may use cookies or browser local storage for limited verification-session
   or device-recognition identifiers. They are used only to help complete verification,
   reduce repeated verification, prevent abuse, and protect service security; they
   are not used for advertising or unrelated tracking.
 * Before WordPress accepts a protected action, the WordPress server sends the VID,
   VKEY, verification token, verification-session identifier, and visitor IP address
   to `https://v41.vaptcha.com/api/verify` for server-side verification. The plugin
   does not send WordPress usernames, passwords, comment text, or other form contents
   to VAPTCHA.

The VAPTCHA service is provided by VAPTCHA:

 * [User Service Agreement](https://www.vaptcha.com/legal#terms)
 * [Privacy Statement](https://www.vaptcha.com/legal#privacy)

By installing and activating the plugin, the site administrator enables this external
service for the selected forms and is responsible for providing any notice required
for the site’s visitors.

### Privacy

Protected forms use the external VAPTCHA service. See the [VAPTCHA Privacy Statement](https://www.vaptcha.com/legal#privacy)
for the information processed for verification, including the limited use of cookies
and browser local storage. No VAPTCHA-powered public credit link is added by this
plugin. Site administrators should disclose this processing in their own privacy
notice where required.

## Installation

 1. Upload the `vaptcha-human-verification` folder to `/wp-content/plugins/`, or install
    the ZIP from the WordPress Plugins screen.
 2. Activate **VAPTCHA Human Verification**.
 3. Open **Settings > VAPTCHA Human Verification**.
 4. Keep the ready-to-use shared unit, or configure your own VID and VKEY.
 5. Select the forms that should require verification and save.

## FAQ

### Is this plugin free?

Yes. The plugin and the ready-to-use shared verification unit are completely free
to use. No registration is required for the shared unit. An independent VAPTCHA 
unit is optional.

### Is registration required?

No. The shared verification unit works immediately after activation. Creating an
independent unit is recommended when you want separate verification statistics.

### Is VKEY exposed to browser developer tools?

No. VKEY is used only by server-side PHP when WordPress calls the VAPTCHA verify
endpoint. It is never included in HTML or JavaScript.

### Does the plugin change my theme or login page styles?

No. The plugin adds hidden fields and a submit listener to standard WordPress hooks.
Verification opens only after the visitor submits a protected form.
