Key Features

1. Multiple Captcha Types

   Choose the captcha style that best fits your security and user experience requirements. Select from Mathematical Captcha (solve simple math problems), Numeric Image Captcha (type numbers from distorted images), or Alphabetic Image Captcha (type letters from images) — all designed to effectively block bots while remaining user-friendly for legitimate visitors.

2. Flexible Form Protection

   Secure the forms that matter most to your business. Enable captcha verification on Login Forms, Signup/Registration Forms, and Password Reset Forms independently or in combination. This granular control ensures you can balance security with user convenience based on each form's risk level.

3. Highly Customizable Settings

   Tailor captcha difficulty and appearance to your exact specifications. For Mathematical Captcha, choose operation types (addition, subtraction, multiplication) and number ranges. For Image Captchas, configure length, include/exclude uppercase letters and special symbols, and control distortion levels to find the perfect balance between security and usability.

4. Multi-Website Support

   Configure different captcha settings for each website in your Odoo instance. Each website can have its own captcha type, enabled forms, and security parameters, providing flexibility for multi-brand or multi-region deployments with varying security requirements.

5. Real-Time Preview & Testing

   See exactly what your users will experience before going live. The built-in preview functionality displays the captcha as it will appear to users, allowing administrators to test different configurations and ensure optimal readability and difficulty before applying changes to production forms.

6. Seamless Integration with Odoo Security

   Works harmoniously with Odoo's native authentication and security systems. The module respects existing access rights, user roles, and security policies while adding an additional layer of protection against automated attacks, ensuring a cohesive security architecture.

Summary

The Website Captcha for Odoo module adds robust, customizable captcha verification to login, signup, and password reset forms. With three captcha types (Mathematical, Numeric Image, Alphabetic Image), real-time preview, multi-website support, and flexible configuration options, this module provides comprehensive bot protection while maintaining excellent user experience.
