Over 43% of websites run on WordPress, making it a favorite target for hackers.
If your site isn’t properly secured, you risk data breaches, downtime, malware injection, and SEO penalties.
In this post, we’ll cover 10 actionable WordPress security tips that’ll help you protect your website from hackers in 2025 and beyond.
1️⃣ Use a Strong Admin Username & Password
Never use “admin” as your username — it’s the first guess hackers make.
Quick Security Tips:
- Use passwords with 12+ characters including symbols & numbers.
- Change your login URL using a plugin.
- Store passwords securely in a manager like Bitwarden or LastPass.
- 👉 Bonus: Use the plugin WPS Hide Login to customize your admin URL (e.g.,
yoursite.com/mylogin123).
2️⃣ Install a Trusted WordPress Security Plugin
A WordPress security plugin protects your website in real time.
Here are some top-rated plugins you can install today:
- Wordfence Security – Real-time firewall & malware scanning
- iThemes Security – 30+ advanced protection tools
- Sucuri Security – Cloud-based firewall & cleanup
💡 All include brute-force protection, file integrity monitoring, and 2FA.
3️⃣ Keep WordPress, Themes & Plugins Updated
Outdated software = open door for hackers.
✅ Always:
- Enable automatic updates for minor versions.
- Manually check for plugin updates weekly.
- Delete unused plugins or themes.
4️⃣ Enable Two-Factor Authentication (2FA)
Adding 2FA helps prevent unauthorized logins even if passwords are stolen.
Recommended Plugins:
- WP 2FA
- Two-Factor Authentication by WP White Security
Use an authenticator app or email-based verification for extra protection.
5️⃣ Limit Login Attempts
Hackers often use brute-force attacks to guess credentials.
Best Plugins:
- Limit Login Attempts Reloaded
- Wordfence (has built-in login limit feature)
Set your limit to 3–5 failed attempts per IP.
6️⃣ Change Default WordPress Login URL
By default, WordPress uses /wp-admin or /wp-login.php.
Changing it makes brute-force attacks harder.
Use WPS Hide Login or iThemes Security to rename your admin URL.
Example: yoursite.com/admin-portal
7️⃣ Disable File Editing in Dashboard
Prevent hackers from editing theme or plugin files via the dashboard.
Add this line in your wp-config.php file:
define( ‘DISALLOW_FILE_EDIT’, true );
8️⃣ Use HTTPS & Install SSL Certificate
Google prioritizes HTTPS websites in search results.
Install a free SSL certificate using Let’s Encrypt or Really Simple SSL plugin.
You’ll see a padlock icon 🔒 in your browser — proof your site is secure.
9️⃣ Backup Your Website Regularly
If something goes wrong, a backup saves your site.
Top Backup Plugins:
- UpdraftPlus
- Backuply
- All-in-One WP Migration
Store backups on Google Drive, Dropbox, or Amazon S3.
🔟 Install a Web Application Firewall (WAF)
A WAF filters out malicious traffic before it reaches your server.
Top WordPress WAFs:
- Cloudflare (Free Plan)
- Sucuri Firewall
- Astra Security
These block DDoS, SQL injection, and XSS attacks automatically
🧠 Bonus: Hide Your WordPress Version
Hackers scan sites to find outdated WordPress versions.
Hide it by adding this code in your theme’s functions.php:
remove_action(‘wp_head’, ‘wp_generator’);
✅ Summary: How to Secure WordPress Site in 2025
- Use strong passwords & 2FA
- Update everything regularly
- Backup & install a WAF
- Enable SSL & disable file editing
