Captcha Code
Version: 3.3
Description
Adds GDPR compatible captcha code anti-spam protection 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/).
- Activate it.
- Click the ‘Captcha’ menu.
- Fill in the options.
- You’re done!

Just use standard Plugin overview page in WordPress admin section and deactivate it or rename plugin folder /wp-content/plugins/captcha-code-authentication over FTP access.
No, it won’t. It’s only loaded on the pages it protects.

They doing spam

I got surprised that, my fresh website sudden installed this plugin automatically. Even i never seen their name ever. They hide the plugin from WP Plugin list and uses as core plugin and uses option on WP Setting. Offering premium plan and doing huge spam. I recommend WP to remove their plugin for doing spam marketing and fraud install.
Not good

Waste of time,
it slows down your site

A PHP session was created by a session_start() function call. This interferes with REST API and loopback requests. The session should be closed by session_write_close() before making any HTTP requests.
on the file wpcaptcha.php you should fix line 40 to 44 with this
if ( !session_id() )
{ session_start( [ 'read_and_close' => true, ] ); }
I had to find it my way out
working yey
