“Password for username XYZ is not correct”. Does this ring a bell? WordPress, one of the most popular content management systems in the world, is renowned for its user-friendly features. However, when it comes to security, there are always opportunities for improvement. One often-overlooked aspect of WordPress security is the customization of login error messages. By altering these messages, you can enhance security and privacy on your WordPress site. This article will guide you through the process of changing login error messages in WordPress and explain why it’s essential for your website’s security.
Why Change Login Error Messages?
WordPress is an open book when it comes to login errors. When a user attempts to log in and makes a mistake, WordPress usually provides a generic error message. Phrases like “Invalid username” or “Incorrect password” make it clear what went wrong. Unfortunately, this level of transparency also helps potential attackers. It lets them know that the username they entered is valid, allowing them to focus solely on cracking the password.
When WordPress clearly communicates the nature of login errors, it inadvertently assists hackers. For example, if a hacker tries to log in with a username, and the error message is “Invalid username,” they now know that the username they used exists in the system. This knowledge is a valuable first step in a brute force attack. By changing login error messages, you can make it more challenging for malicious actors to gain insight into your system.
Steps to Change Login Error Messages in WordPress
Changing login error messages in WordPress is a straightforward process. Here’s a step-by-step guide to get you started:
Edit your child’s theme functions.php
File
If you haven’t already, create a child theme for your WordPress website. This is crucial because child themes preserve your changes even when the parent theme is updated. You can create a child theme by making a new directory in your WordPress themes folder and adding a style.css
file with the necessary information. Use an FTP client or your hosting service’s file manager to access your child theme’s directory. You should find a functions.php
file there. If it doesn’t exist, create one. Edit the functions.php
file using your preferred text or code editor. This file is where you’ll add the custom PHP code to modify the login error messages.
Modify the Login Error Messages
To change the error messages, you can use the login_errors
filter hook. Here’s an example of how to customize the error message:
function custom_login_errors($error) {
// Modify the login error message
$error = "Your custom error message here.";
return $error;
}
add_filter('login_errors', 'custom_login_errors');
Replace "Your custom error message here."
with the message you want to display to users when they enter incorrect login credentials.
Test Your Changes
You can now test your login error message changes by attempting to log in with incorrect credentials. This will ensure your custom error message is displayed correctly.
The above quote is from a famous movie, hope y’all know it.

Changing login error messages in WordPress can play a crucial role in enhancing your website’s security. By providing less information to potential attackers, you make it more challenging for them to gain insights into your system, improving your defenses against brute force attacks.

Remember to create a child theme and follow best practices to preserve your changes and ensure the security of your website.
