<h4>Supported CAPTCHA Providers</h4>
Cloudflare Turnstile 
Turnstile is Cloudflare’s modern, privacy-preserving alternative to traditional CAPTCHAs. It uses sophisticated browser challenges that are invisible to most legitimate users while effectively blocking bots.
Built-in Fallback CAPTCHA 
Our self-hosted CAPTCHA system offers two challenge types: 
– Math Challenges: Simple arithmetic problems (e.g., “What is 7 + 3?”) 
– Text Recognition: Warped text characters requiring human recognition
Both are effective against automated bots while remaining accessible to humans.
<h4>Comparison with Other CAPTCHA Plugins</h4>
Unlike many CAPTCHA plugins that rely solely on external services, SecureGate Captcha Lite provides: 
– Multiple provider support with automatic fallback 
– Self-hosted option for complete independence 
– Advanced rate limiting built-in 
– Modern, user-friendly admin interface 
– Regular updates and active development 
– Clean, well-documented code
<h3>Privacy & Data Collection</h3>
What Data Does This Plugin Collect?
SecureGate Captcha Lite is designed with privacy as a core principle:
Stored Locally (in your WordPress database as transients): 
* Anonymized IP addresses (last octet removed) 
* Timestamp of verification attempts 
* Success/failure status of CAPTCHA verifications 
* Failed attempt counters for rate limiting
NOT Stored: 
* User emails or usernames 
* Personal identifying information 
* Browser fingerprints 
* Tracking cookies (plugin-side) 
* Permanent user profiles
External Service Data: 
When Cloudflare Turnstile is enabled, user browser data is sent to Cloudflare for bot detection. Please review <a href="https://www.cloudflare.com/privacypolicy/" rel="nofollow ugc">Cloudflare’s Privacy Policy</a> for details.
When using the Built-in CAPTCHA, NO external services are contacted.
Data Retention: 
All logs are stored as WordPress transients and automatically deleted after 7 days. Administrators can disable logging entirely in settings.
Right to Erasure: 
No personal data is collected that would require manual erasure requests under GDPR.

<h4>Contributing</h4>
If you would like to contribute or fork Project Force Field, we currently have a repo on Bitbucket. You can <a href="https://bitbucket.org/oriongroup/project-force-field/" rel="nofollow ugc">find it here</a>
<h4>Features!</h4>
<ul>
<li>Sends a 403 error code to anyone visiting /wp-login.php – All brute force attacks we’ve seen target /wp-login.php. By responding with a 403 error, your WordPress files aren’t loaded, the Database isn’t queried, and the attacker doesn’t figure out your password.</li>
<li>Changes the default login url – While a so-called hacker is being deflected by your new Force Field, you will log in with ease at /wp-admin/. When you do that, WordPress will redirect you to the new, proper login url.</li>
<li>Automatically changes the login when a Brute Force Attack is detected – When too many login failures occur within a minute, Project Force Field shifts polarity! The new login you previously used now responds with a 403 error, and a large random number is now used as your login url! After some time, the login will return back to normal.</li>
<li>Unlimited polarity shifts – If a Brute Force Attacker gets smart and writes a script to check for the new login url, Project Force Field will continue to detect the attack and change the login.</li>
<li>Define the login yourself – By defining <code>OGFF_LOGIN</code> in your wp-config.php, you can set the login to be almost anything you want.</li>
<li>Stops WordPress User Enumeration Exploit – Many brute force attacks use the WordPress User Enumeration exploit to easily figure out valid usernames. We stop that to protect your site, and respond with a 403 to save your server.</li>
</ul>
<h4>Future Features!</h4>
<ul>
<li>Multisite Support – It’s not there yet, that’s pretty lame, so I’m going to fix that before anything else!</li>
<li>Adjust the login failure threshold – Currently, Project Force Field assumes a brute force is underway when there have been 30 login failures within a minute. This might not be ideal for large websites, so we want to let you increase that amount to 300 if needed.</li>
<li>Add optional email notification for brute force events – If you want to know when your website is under attack, we want to let you know. In a near future version, we will let you add email addresses to be notified of brute force attacks, and any other important related events that we add in the future.</li>
<li>Add last resort .htaccess password lockdown – If a so-called hacker writes a script that continues to learn the new login url, Project Force Field won’t help much. In an upcoming version, we will check to see how many times the login url was changed, determine if the Brute Force Attack is smart, and lockdown the login with an .htaccess password.</li>
</ul>
