Custom CF7 reCAPTCHA

Integrates Google reCAPTCHA v2 or v3 with Contact Form 7, replacing the need for third-party reCAPTCHA plugins.

Description

This plugin provides a secure and customizable integration of Google reCAPTCHA with Contact Form 7. It allows you to choose between reCAPTCHA v2 ("I'm not a robot" checkbox) and the invisible, score-based reCAPTCHA v3.

You can configure all settings, including site keys, secret keys, language, and theme (for v2), from a dedicated settings page in the WordPress admin area.

Features

• Dual Version Support: Choose between reCAPTCHA v2 and v3.
• Customizable Keys: Easily enter your site and secret keys.
• Language Support: Set a specific language for the reCAPTCHA widget.
• Theme Selection: Choose between a light or dark theme for the v2 checkbox.
• Secure Backend Verification: All form submissions are verified on the server-side against Google's API.
• Score-Based Protection (v3): Submissions with a score below the threshold are marked as spam.
