原文外掛簡介
MyFast Login Guard provides two things hosting clients actually need:
Login protection
Rename your login page to a custom URL — direct access to /wp-login.php returns a 404
Limit login attempts — lock out an IP after a configurable number of failures
Configurable lockout duration (default: 5 attempts, 30-minute lockout)
IP whitelist — your own IPs are never locked out
Optional email notification when a lockout is triggered
Manual unlock from the Lockout Log page
Server information and error log
Full PHP environment: version, memory, OPcache, extensions, disabled functions, error log path
WordPress environment: version, debug flags, memory limits, active plugin count
Server details: software, IP, document root, HTTPS status, OS
Database: MySQL/MariaDB version, database size
Scheduled cron events with overdue detection
Error log viewer: reads WordPress debug.log (or PHP error log), filterable by Fatal / Warning / Notice, with one-click clear
Design principles
No external API calls
No cronjobs
No .htaccess rewriting
No front-end database queries
Assets load only on the plugin’s own admin pages
