Simple Login Captcha
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. The correct number is displayed above the field by a small JavaScript code. Compatible with the WooCommerce login form. Compatible with multisite. Demo https://nikolaydev.com/wp-login.php Simple No complicated features No settings No image generation No API No sessions No cookies No IP address detection No personal data collection No vulnerabilities in the programming code Recommendation 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 Disable XML-RPC. Notice 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.
