ReCaptcha v2 for Contact Form 7 is a lightweight compatibility plugin designed to bring back Google reCAPTCHA v2 support to Contact Form 7 after version 5.1 removed the [recaptcha] tag in December 2018. Instead of introducing custom implementations or external wrappers, the plugin restores the original functionality from Contact Form 7 v5.0.5, preserving the familiar behavior many site owners relied on.
Built for sites running on WordPress, this plugin allows administrators to continue using reCAPTCHA v2 without modifying core files or applying unsafe patches.
If the plugin is installed before upgrading Contact Form 7 from v5.0.5 to v5.1+, existing API keys are automatically migrated. After that, administrators only need to enable reCAPTCHA v2 from the plugin settings page. Once configured, the protection works exactly as it did in earlier Contact Form 7 versions.
