WordPress Security Hardening: The Complete 2026 Checklist

Why WordPress Security Matters

WordPress powers 43% of all websites, making it a primary target for hackers. A single breach can destroy your business reputation.

1. Change the Default Admin Username

Never use "admin" as your username. This is the first thing brute force bots try.

2. Use Strong Passwords + 2FA

Enable two-factor authentication. Use a password manager to generate strong, unique passwords.

3. Keep Everything Updated

WordPress core, plugins, and themes must be updated regularly. Outdated plugins are the #1 cause of hacks.

4. Install a Security Plugin

Wordfence or Sucuri provide firewall protection, malware scanning, and login attempt limiting.
