Advanced SmartCaptcha

Unofficial Community Integration:
This plugin is a community-made integration for the Yandex SmartCaptcha service. It is not developed, endorsed, or supported by Yandex.

Enhance your WordPress site’s security by integrating the powerful Yandex SmartCaptcha anti-bot system. This plugin allows you to easily add SmartCaptcha to your website forms to effectively combat spam and automated abuse.

How it works?
This plugin acts as a bridge between your WordPress site and the external Yandex SmartCaptcha service. The smart system analyzes user behavior. If it resembles a bot, the user is prompted to solve a simple task. Real people often pass the check instantly and unnoticed.

• FREE: Comment form (ideal for blogs)
• PRO: Invisible captcha
• PRO: Login form (protection against password brute-force attacks)
• PRO: Registration form (combat fake users)
• PRO: Password recovery form
• PRO: Access to the website is granted only after passing the captcha

  • WPForms (Lite & Pro)
  • Elementor Pro

Your benefits:

• Less spam: Clean comments and user database.
• Better security: Protection against brute-force attacks and automated registrations.
• Easy to use: Set up in 5 minutes with no programming skills required.

Start with the free protection for the comment form, and upgrade to a license if you need to unlock all the plugin’s advanced features!
