<p>A simple captcha for the WordPress login form. To be able to login, the user is required to enter a random 3-digit number in a text field.</p>
<p>The correct number is displayed above the field by a small JavaScript code. Compatible with the WooCommerce login form. Compatible with multisite.</p>
<h4>Demo</h4>
<p><a href="https://nikolaydev.com/wp-login.php" rel="nofollow ugc">https://nikolaydev.com/wp-login.php</a></p>
<h4>Simple</h4>
<ul>
<li>No complicated features</li>
<li>No settings</li>
<li>No image generation</li>
<li>No API</li>
<li>No sessions</li>
<li>No cookies</li>
<li>No IP address detection</li>
<li>No personal data collection</li>
<li>No vulnerabilities in the programming code</li>
</ul>
<h4>Recommendation</h4>
<p>Bots can also try to login with the XML-RPC feature of WordPress! Very rarely plugins also need this (like the Jetpack plugin). But if you don’t use it, I recommend that you disable it. You can use the super simple one-line plugin <a href="https://wordpress.org/plugins/disable-xml-rpc/" rel="ugc">Disable XML-RPC</a>.</p>
<h4>Notice</h4>
<p>This is a simple plugin designed to protect against random bots that try to login on your site. But if a person actually looks at the code of this plugin and specifically designs a new bot that targets this plugin, this bot would be able to bypass the protection.</p>
