描述
eSherpa Login Guard effectively and intelligently protects your WordPress site from brute-force attacks – Swiss precision, completely without external dependencies.
Key Features:
- Honeypot-first bot defense: JavaScript Honeypot detects non-browser bots and triggers immediate lockout logic.
- Protected username trap: Immediate lockout for defined usernames (e.g., “admin”, “test”), independent of the regular counter.
- Proactive User-Agent blocking: Block known bot signatures before login processing (exact match or substring mode).
- Blocked User-Agent attempt log: Separate log table for blocked User-Agent requests including matching pattern.
- WordPress hardening options: Disable XML-RPC (with fake-user honeypot response), hide REST user endpoint, and block author archive enumeration.
- Optional bot password capture: Store attempted passwords from detected JS-honeypot bots for incident analysis.
- Neutral login error option: Hide username enumeration by using neutral WordPress login error responses.
- Live security visibility: Live alarm in admin, lockout badge in menu, and detailed failed-attempt logs with IP/User-Agent filters.
- Progressive lockout durations: Lockout time increases on repeat offenses (e.g., 15 30 60 120 minutes).
- Login page guidance: Clear countdown and “X attempts remaining” notice for transparent lock state.
- Privacy-compliant: IPs stored only as anonymized hashes.
- Automatic cleanup of old failed attempts (configurable).
- Mobile-friendly admin tables: Horizontal scrolling for wide security tables on small screens, including swipe hint.
- Email notification to admin on attacks against existing users.
Developed in Switzerland – fast, clean, performant, and multilingual ready.
Compatible with WordPress 6.9 and tested up to PHP 8.5.3.

- Done – protection runs automatically.
常见问题
-
How are IPs stored?
-
Only as anonymized MD5 hashes – no plain-text IPs in the database (GDPR-compliant).
-
Can I manually unblock IPs?
-
Yes – directly in the admin overview with one click (counter is reset).
-
Does it work with caching plugins?
-
Yes – protection hooks early on wp-login.php, before caching.
-
What happens on successful login?
-
All counters and locks for that IP are immediately cleared.
-
Can I still use XML-RPC?
-
Yes – simply disable the option. When enabled, XML-RPC is fully disabled and a honeypot is activated.
