Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

Overview

About this plugin

HSArticle Math CAPTCHA for Forms adds a math CAPTCHA to any WordPress form. No API keys. No third-party services.

No configuration needed to get started.

Features:

  • Math CAPTCHA — addition, subtraction, multiplication with sensible number ranges
  • Two display modes: distorted canvas image (bot-resistant) or plain text (accessible)
  • Server-side validation — answer stored in PHP session with HMAC signature, never exposed to the client
  • Honeypot field — silent bot trap alongside the math challenge
  • Rate limiting — blocks IPs after 10 failed attempts per 10 minutes
  • Refresh button — generate a new question without reloading
  • WPForms auto inject — protect any WPForms (free or pro) without adding a shortcode
  • Registered as a CF7 form tag — no unknown tag warnings in the CF7 editor
  • Session only starts on pages that actually contain a form — no impact on page caching elsewhere
  • Clean admin page under its own menu — not buried under Settings

Supported form plugins:

  • Contact Form 7
  • WPForms (Free and Pro)
  • Any HTML form via the [hs_mcf_captcha] shortcode
