CAPTCHA for WordPress without tracking
The official CaptchaCore plugin protects login, registration, comments and lost password — no cookies, no image puzzles, processing on servers in Germany.
In three steps
Protect WordPress in a few minutes
Install the plugin
In WordPress go to Plugins → Add New, search for “CaptchaCore” and activate it. Updates arrive through WordPress as usual.
Enter the site key
Create a site in the customer area and paste site key and secret under Settings → CaptchaCore.
Tick the forms
Login, registration, comments, lost password — each form selectable individually. Done, no code required.
What you get
Built for WordPress, not just compatible
All core forms
Login (including wp_login_form), registration, lost password, comments and WooCommerce product reviews.
WooCommerce
Login, registration and lost password on “My Account” plus the classic checkout — each switchable individually.
Formidable Forms & Elementor
A native field type for Formidable, a widget and a form field for Elementor and Elementor Pro.
Fail-open
If the service is ever unreachable, the plugin lets the form through and logs it — nothing gets stuck.
Reverse-proxy ready
Cloudflare, Nginx proxy and the like: proxy headers are only evaluated when you switch it on.
Multilingual
German, English, Spanish, French — the widget adopts the language of the page.
No image puzzles
Proof of work and behavioural analysis instead of traffic lights and crosswalks — humans click once, bots compute themselves to death.
Servers in Germany
Processing on our own servers, no transfer to third countries, no cross-site tracking.
16 KB, no framework
The widget loads fast, never blocks the interface and works with keyboard and screen readers.
Frequently asked questions about WordPress
Do I need an entry in my cookie banner?
No. The widget sets no cookies and loads nothing from third parties. The privacy centre offers a ready-made paragraph for your privacy policy.
Does it work with the WooCommerce checkout block?
The classic checkout (shortcode) yes, the block-based checkout not yet — there login and registration still protect you. Support follows as soon as WooCommerce offers a stable interface.
What does the plugin cost?
Nothing. The plugin is open source. The free plan is enough for small sites; larger sites pick a plan by verifications per month.
