WordPress Security Checklist (2025 Updated)
WordPress powers over 43% of the web, making it a major target for hackers. But with the right security practices, you can turn your WordPress website into a fortress. This updated 2025 checklist includes every essential security measure—firewalls, malware scanning, backups, login protection, file security, database hardening, and more.
1
1. Keep WordPress Core, Themes & Plugins Updated
Updates patch security vulnerabilities instantly.
The majority of hacked WordPress sites were running outdated versions of plugins or themes. Keeping everything updated is the first and most important security step.
Checklist:
- Enable automatic updates for minor WordPress versions
- Update plugins weekly
- Delete unused themes & plugins
- Use themes from trusted sources only

2. Use a Security Plugin or Firewall
A firewall blocks malicious traffic before it reaches your site.
Recommended security plugins:
- Wordfence Security (powerful firewall + malware scanner)
- iThemes Security Pro (login protection + hardening)
- All in One WP Security (free and effective)
- Cloudflare Firewall (DNS-level security)
A firewall prevents brute force attacks, SQL injections, and bot traffic.

3. Use Strong Administrator Passwords
Weak passwords are the #1 cause of hacked WordPress sites.
- Use at least 12 characters
- Include letters, numbers, and special characters
- Use a password manager (LastPass, Bitwarden)
- Change passwords every 6–12 months
Also avoid using “admin” as your username.
4
4. Enable Two-Factor Authentication (2FA)
Adds an extra layer of protection for logins.
Even if a hacker gets your password, they still cannot access your admin panel without the second verification step.
Best 2FA plugins:
- Wordfence Login Security
- Google Authenticator
- iThemes Security

5. Change the Default Login URL
Make it harder for bots to brute-force your login.
The default WordPress login URL (/wp-login.php) is a magnet for attackers. Changing it reduces brute force attempts significantly.
Plugins that allow login URL change:
- WPS Hide Login
- iThemes Security
6
6. Limit Login Attempts
Block users who repeatedly try incorrect passwords.
This stops bots that try thousands of password combinations automatically.
Useful plugins:
- Limit Login Attempts Reloaded
- Wordfence (built-in)
7
7. Disable File Editing Inside WordPress
Prevents attackers from injecting malicious code.
Add this line in wp-config.php:
define('DISALLOW_FILE_EDIT', true);
This disables theme and plugin file editing inside the WP dashboard.
8
8. Install SSL (HTTPS)
Encrypts user data and protects login credentials.
Use Cloudflare or your hosting provider to enable SSL for free.
Benefits:
- Prevents data interception
- Improves SEO
- Essential for security compliance
9
9. Take Regular Automatic Backups
Backups = immediate recovery from attacks.
Recommended backup plugins:
- UpdraftPlus
- BlogVault
- Jetpack Backup
- All-in-One WP Migration
Always store backups externally (Google Drive, Dropbox, S3).
10
10. Harden wp-config.php
Protect your database credentials.
Security improvements:
- Move wp-config.php above public_html (if hosting supports)
- Add file permissions 400 or 440
- Set unique authentication keys
