Fail2WP for WordPress

This WordPress plugin provides security functionality and integration with Fail2ban.

Basic security functionality includes:

  • Disabling login with username (require e-mail address)
  • Preventing user enumeration (?author=nnn)
  • Less detailed error messages on login failures
  • Minimum username length
  • Blocking specific usernames from being used to register new users
  • Requiring e-mail address matching for new user registrations
  • Warning about new user role setting
  • Blocking of portions or all of WordPress REST API

  • Detection of Cloudflare IP addresses for logging of actual IP addresses
