Description
Jacklabs Form Sentinel helps reduce automated spam on WordPress comments, registration, frontend login forms rendered with wp_login_form(), Contact Form 7, and WooCommerce account forms.
The default login form at wp-login.php is intentionally excluded to reduce the risk of administrators being locked out by an incorrect key configuration.
This plugin requires Google reCAPTCHA v2 “I’m not a robot” Checkbox keys. It does not support reCAPTCHA v3 keys.
External services
This plugin connects to Google reCAPTCHA, a service provided by Google LLC, only after an administrator saves a Site Key and Secret Key.
On pages containing protected forms, the plugin loads JavaScript from https://www.google.com/recaptcha/api.js. Google may receive visitor information such as IP address, browser and device information, cookies, and interaction data. When a visitor submits a protected form, the plugin sends the reCAPTCHA response token, configured Secret Key, and visitor IP address to https://www.google.com/recaptcha/api/siteverify to determine whether the submission is valid.
This data is sent when a protected form is displayed or submitted. The service is necessary for the plugin’s reCAPTCHA functionality.

FAQ
-
Does this protect the default WordPress login page?
-
No. The form at
wp-login.phpis intentionally excluded. A frontend form produced bywp_login_form()can be protected. -
Which reCAPTCHA key type should I use?
-
Create reCAPTCHA v2 Checkbox keys for your domain in Google reCAPTCHA Admin.
-
The protected submission is rejected. This fail-closed behavior prevents unverified submissions from bypassing protection.
