About Captcha Code
From the official readme · v3.33Description
Captcha adds GDPR compatible captcha code anti-spam protection (like Google ReCaptcha) to WordPress forms – comments form, registration form, lost password form, and login form. In order to post comments or register, users have to type in the code shown on the image. This prevents spam from automated bots & adds security. No external services (like Google ReCaptcha) are used. No API keys are needed, and no user-identifiable data is used so it’s GDPR compatible.
Features
- Captcha position – comments form, login form, registration form, or lost password form.
- Letters type – capital letters, small letters, or captial & small letters.
- Captcha type – alphanumeric, alphabets or numbers.
- Translation enabled.
Installation
- Download the plugin.
- Upload to your blog (/wp-content/plugins/).
