12 Most Useful .htaccess Tricks for WordPress
What is .htaccess File and How to Edit it?
The .htaccess file is a server configuration file. It allows you to define rules for your server to follow for your website.
WordPress uses .htaccess file to generate SEO friendly URL structure. However, this file can do a lot more.
The .htaccess file is located in your WordPress site’s root folder. You will need to connect to your website using an FTP client to edit it.
Before editing your .htaccess file, it is important to download a copy of it to your computer as backup. You can use that file in case anything goes wrong.
Having said that, let’s take a look at some useful
.htaccess tricks for WordPress that you can try.
1. Protect Your WordPress Admin Area
You can use .htaccess to protect your WordPress admin area by limiting the access to selected IP addresses only. Simply copy and paste this code into your .htaccess file:
02 | AuthGroupFile /dev/null |
03 | AuthName "WordPress Admin Access Control" |
08 | # whitelist Syed's IP address |
09 | allow from xx.xx.xx.xxx |
10 | # whitelist David's IP address |
11 | allow from xx.xx.xx.xxx |
Don’t forget to replace xx values with your own IP address. If you use more than one IP address to access the internet, then make sure you add them as well.
For detailed instructions, see our guide on how to
limit access to WordPress admin using .htaccess.
2. Password Protect WordPress Admin Folder

If you access your WordPress site from multiple locations including public internet spots, then limiting access to specific IP addresses may not work for you.
You can use .htaccess file to add an additional password protection to your WordPress admin area.
First, you need to generate a .htpasswds file. You can easily create one by using this
online generator.
Upload this .htpasswds file outside your publicly accessible web directory or /public_html/ folder. A good path would be:
/home/user/.htpasswds/public_html/wp-admin/passwd/
Next, create a .htaccess file and upload it in /wp-admin/ directory and then add the following codes in there:
02 | AuthUserFile /home/yourdirectory/.htpasswds/public_html/wp-admin/passwd |
03 | AuthGroupFile /dev/null |
05 | require user putyourusernamehere |
Important: Don’t forget to replace AuthUserFile path with the file path of your .htpasswds file and add your own username.

password protect WordPress admin folder.

Many WordPress security experts recommend disabling directory browsing. With directory browsing enabled, hackers can look into your site’s directory and file structure to find a vulnerable file.
To disable directory browsing on your website, you need to add the following line to your .htaccess file.
For more on this topic, see our guide on how to disable directory browsing in WordPress.
4. Disable PHP Execution in Some WordPress Directories
Sometimes hackers break into a WordPress site and install a backdoor. These backdoor files are often disguised as core WordPress files and are placed in /wp-includes/ or /wp-content/uploads/ folders.
An easier way to improve your WordPress security is by disabling PHP execution for some WordPress directories.
You will need to create a blank .htaccess file on your computer and then paste the following code inside it.
Save the file and then upload it to your /wp-content/uploads/ and /wp-includes/ directories. For more information check out our tutorial on how to disable PHP execution in certain WordPress directories.
5. Protect Your WordPress Configuration wp-config.php File
Probably the most important file in your WordPress website’s root directory is wp-config.php file. It contains information about your WordPress database and how to connect to it.
To protect your wp-config.php file from unathorized access, simply add this code to your .htaccess file:
6. Setting up 301 Redirects Through .htaccess File
Using 301 redirects is the most SEO friendly way to tell your users that a content has moved to a new location. If you want to properly manage your 301 redirects on posts per post basis, then check out our guide on how to setup redirects in WordPress.
On the other hand, if you want to quickly setup redirects, then all you need to do is paste this code in your .htaccess file.
1 | Redirect 301 /oldurl/ http: |
2 | Redirect 301 /category/television/ http: |
7. Ban Suspicious IP Addresses
Are you seeing unusually high requests to your website from a specific IP address? You can easily block those requests by blocking the IP address in your .htaccess file.
Add the following code to your .htaccess file:
Don’t forget to replace xx with the IP address you want to block.
8. Disable Image Hotlinking in WordPress Using .htaccess
Other websites directly hotlinking images from your site can make your WordPress site slow and exceed your bandwidth limit. This isn’t a big issue for most smaller websites. However, if you run a popular website or a website with lots of photos, then this could become a serious concern.
You can prevent image hotlinking by adding this code to your .htaccess file:
1 | #disable hotlinking of images with forbidden or custom image option |
3 | RewriteCond %{HTTP_REFERER} !^$ |
4 | RewriteCond %{HTTP_REFERER} !^http(s)?: |
5 | RewriteCond %{HTTP_REFERER} !^http(s)?: |
6 | RewriteRule \.(jpg|jpeg|png|gif)$ – [NC,F,L] |
This code only allows images to be displayed if the request is originating from wpbeginner.com or Google.com. Don’t forget to replace wpbeginner.com with your own domain name.

9. Protect .htaccess From Unauthorized Access
As you have seen that there are so many things that can be done using the .htaccess file. Due to the power and control it has on your web server, it is important to protect it from unauthorized access by hackers. Simply add following code to your .htaccess file:
1 | <files ~ "^.*\.([Hh][Tt][Aa])"> |
10. Increase File Upload Size in WordPress
There are different ways to increase the file upload size limit in WordPress. However, for users on shared hosting some of these methods do not work.
One of the methods that has worked for many users is by adding following code to their .htaccess file:
1 | php_value upload_max_filesize 64M |
2 | php_value post_max_size 64M |
3 | php_value max_execution_time 300 |
4 | php_value max_input_time 300 |
This code simply tells your web server to use these values to increase file upload size as well as maximum execution time in WordPress.
11. Disable Access to XML-RPC File Using .htaccess
Each WordPress install comes with a file called xmlrpc.php. This file allows third-party apps to connect to your WordPress site. Most WordPress security experts advise that if you are not using any third party apps, then you should disable this feature.
There are multiple ways to do that, one of them is by adding the following code to your .htaccess file:
1 | # Block WordPress xmlrpc.php requests |
For more information, see our guide on how to disable XML-RPC in WordPress.
12. Blocking Author Scans in WordPress
A common technique used in brute force attacks is to run author scans on a WordPress site and then attempt to crack passwords for those usernames.
You can block such scans by adding the following code to your .htaccess file:
1 | # BEGIN block author scans |
4 | RewriteCond %{QUERY_STRING} (author=\d+) [NC] |
6 | # END block author scans |
For more information, see our article on how to discourage brute force attacks by blocking author scans in WordPress.
