8 Vital Tips and Hacks to Protect Your WordPress Admin Area

Here are some tips for your WordPress

1. Create Custom Login Links

It is very obvious that in order to access the WordPress admin panel, all one has to do is type in the url of the site with /wp-login.php. Now if you used a same password in more than one location, and it was jeopardized then it is easy for the hacker to hack your site. A plugin called Stealth Login allows you to create custom URLs for logging in, logging out, administration and registering for your WordPress blog. You can also enable “Stealth Mode” which will prevent users from being able to access ‘wp-login.php’ directly. You can then set your login url to something more cryptic. This won’t secure your website perfectly, but if someone does manage to crack your password, it can make it difficult for them to find where to actually login. This also prevents any bots that are used for malicious intents from accessing your wp-login.php file and attempting to break in.

2. Pick a Strong Password

This is a very obvious step, but we must mention it as it can’t be emphasized enough. Do not use the same password in other places. Try to make each password different and hard to guess. Use the WordPress Password Strength Detector to your advantage and make your password strong. Another thing you want to do is change your password periodically, so even if some has guessed your password, it is useless to them once you have changed it.

3. Limit Login Attempts

Sometimes the hacker might think they know your password, or they might develop a script to guess your password. In that case what you need to do is limit the login attempts. You can easily do so by using a plugin called Login Lockdown which will lock a user out if they entered the wrong password more than the specified time. They will be locked out for a specified time. You can control the settings via your wp-admin panel.

4. Use Secure SSL Login Pages

You can login to WordPress Admin Panel through the encrypted channels with SSL meaning your session URLs will have https://. You must confirm with your webhosts that you have Shared SSL, or you own a SSL certificate. Once you have confirmed paste the following code in your wp-config.php file:

define(’FORCE_SSL_ADMIN’, true);


There is also a plugin called Admin SSL that will force SSL on all pages. It is easier if you run this plugin, but it is only compatible with version 2.7 and above.

5. Password Protect WP-Admin Directory

There is nothing wrong with having two passwords. It just adds another level of security to your WordPress Admin Area. This can be done by using a plugin called AskApache Password Protect. It encrypts your password and creates the .htpasswd file, as well as setting the correct security-enhanced file permissions on both. You can also use cPanel Password Protection on a Directory if you are using a cPanel Web Host to password protect wp-admin directory.

6. Limit Access via IP Address

You can limit access to your WP-Admin Panel and only allow certain IP Addresses to access. All you have to do is create a .htaccess file in /wp-admin/ folder if there is not one there already. Paste the following code:

AuthUserFile /dev/null
AuthGroupFile /dev/null
AuthName “WordPress Admin Access Control”
AuthType Basic

order deny,allow
deny from all
# whitelist Syed’s IP address
allow from xx.xx.xx.xxx
# whitelist David’s IP address
allow from xx.xx.xx.xxx
# whitelist Amanda’s IP address
allow from xx.xx.xx.xxx
# whitelist Muhammad’s IP address
allow from xx.xx.xx.xxx
# whitelist Work IP address
allow from xx.xx.xx.xxx


Change the IP Address and it will work. The downside to this hack is that if you ever want to access the admin panel from some other place, you won’t be able to do so unless you add that extra IP in your .htaccess file.

Update: In the comments Henry suggested an alternate way using htpasswd and combo with the IP which will allow you to enter from other places as well. Check it out here.

7. Never use “admin” Username

This is the first user that is created when WordPress is installed. You should never use or keep this user. Because in the past multiple loopholes have been found that are linked to Brute Force Attack and admin username, you should refrain from using it. You should create another user using your WordPress admin panel, and assign administrator roles to it. Try to make this username something that is not obvious, so it is harder for the hacker to guess. Then delete the admin user altogether to stay on the safe side.

8. Remove Error Message on the Login Page

When you enter a wrong password or an invalid username, you get an error message in the login page. So if a hacker gets one thing right, the error message will help them identify that. Therefore it is recommended if you remove that error message entirely. Open your functions.php located in your theme folder and paste the following code:

add_filter(’login_errors’,create_function(’$a’, “return null;”));


A plugin called Secure WordPress also accomplishes this and it has other features as well. Check it out to see if you are interested.
