The Ultimate WordPress Security Hardening Checklist (25 Proven Steps)

WordPress powers over 43% of the internet, making it the primary target for automated malware bots and brute-force scanners.

1. Protect wp-login.php & Enforce 2FA

Never keep the default 'admin' username. Change the login slug (e.g. to /studio-auth) and require Two-Factor Authentication via Google Authenticator on all administrator accounts.

2. Disable XML-RPC and User Enumeration

Unless using the WordPress mobile app, disable xmlrpc.php in your server .htaccess file to block automated DDoS and password cracking attacks.

3. Lock File Editing in wp-config.php

Add define('DISALLOW_FILE_EDIT', true); to prevent compromised admin credentials from injecting PHP backdoors directly inside theme editors.
