This WordPress plugin makes your login responses more unpredictable to brute-force bots.
Adds a subtle security layer by sending an HTTP 403 Forbidden status on failed login attempts. This simple trick confuses brute-force bots that expect a 200 or 302 response and often makes them give up immediately.
WordPress normally returns HTTP 200 OK on failed login attempts, which makes it easy for brute-force bots to detect success or failure.
This plugin changes that behavior — when a login fails, the server responds with HTTP 403 Forbidden instead of 200 OK.
This plugin provides a basic form of login URL obfuscation designed to confuse trivial automated scanners and bots. It is best regarded as a first-step mitigation rather than a comprehensive security solution. Determined attackers or more advanced bots can bypass simple obfuscation, so we strongly recommend using this plugin only as one layer within a broader security strategy — for example: enforce strong passwords, enable two-factor authentication, limit login attempts, keep WordPress and plugins updated, and use a web application firewall or security plugin. Never rely solely on obscurity; combine multiple proven defenses for real protection.
Why it works
- Bots rely on predictable responses (200 = fail, 302 = success).
- A 403 status confuses many automated tools and brute-force scripts.
- Some bots will slow down or stop attacking altogether.
