.htaccess file plays a critical role in securing a WordPress website. When configured correctly, it can help prevent unauthorized access, reduce attack surfaces, and add an extra layer of protection at the server level. However, outdated or incorrect rules can break your site or create a false sense of security.This guide provides a modern, Apache 2.4–compatible, and SEO-friendly approach to securing WordPress using .htaccess, following current best practices.
What Is .htaccess and Why Is It Important?
.htaccess (hypertext access) is a directory-level configuration file used by Apache web servers. It allows website owners to control behavior such as:
- Access restrictions
- Directory permissions
- URL rewriting
- Basic security hardening
Because WordPress relies heavily on Apache rewrite rules, any mistake in .htaccess can impact site availability or performance, making it essential to use tested and modern configurations.
Before You Begin: Important Precautions
Before editing .htaccess:
- Always take a backup of the existing file
- Ensure your server runs Apache 2.4 or newer (most modern hosts do)
- Avoid copying random rules from outdated blogs or forums
1. Protect the .htaccess File Itself
Your .htaccess file should never be accessible publicly.
Recommended (Apache 2.4):
This ensures attackers cannot read or manipulate your server rules.
2. Secure wp-config.php
The wp-config.php file contains database credentials and security keys. It must be protected.
This is one of the most important WordPress hardening steps.
3. Disable Directory Listing
Directory browsing can expose file structures and sensitive assets.
This prevents attackers from listing files in directories that lack an index file.
4. Prevent PHP Execution in Uploads Directory
Most WordPress malware attacks attempt to execute malicious PHP files from the uploads directory.
Create a .htaccess file inside:
Add the following:
This allows images and media files while blocking PHP execution.
5. Restrict Access to the WordPress Admin Area (Optional)
If you use a static IP address, you can restrict access to /wp-admin/.
Inside /wp-admin/.htaccess:
Warning: Do not use this method if your IP changes frequently, or you may lock yourself out.
6. Disable XML-RPC If Not Needed
XML-RPC is a common target for brute-force and DDoS attacks.
If you don’t use mobile apps or external publishing tools, disable it:
7. Do NOT Rely on .htaccess for SQL Injection Protection
Older blogs often claim .htaccess can prevent SQL injection using rewrite rules. This is no longer true.
.htaccess cannot:
- Detect modern SQL injection patterns
- Stop plugin-based vulnerabilities
- Replace application-level security
Instead, you should:
- Keep WordPress core, themes, and plugins updated
- Use a Web Application Firewall (WAF)
- Install a trusted security plugin
Additional WordPress Security Best Practices
.htaccess hardening should be part of a layered security strategy, including:
- Strong passwords and unique admin usernames
- Two-factor authentication (2FA)
- Regular malware scans
- Automated backups
- Limited user roles and permissions
Common Mistakes to Avoid
- Using Apache 2.2 syntax on modern servers
- Blocking entire directories like
wp-content - Copying unverified code snippets
- Forgetting to back up

.htaccessalone can secure WordPress
Final Thoughts
When configured correctly, .htaccess is a powerful tool for improving WordPress security. However, modern threats require modern solutions.
