How to Disable Login Hints in WordPress Login Error Messages

By default, WordPress shows error messages on the login page when someone enters the wrong username or password. While these messages are meant to help users, they can also give clues to hackers trying to break into your site.

Disabling these login hints is a simple way to strengthen your site’s security.

By hiding these details, you make it harder for hackers to guess your credentials. We always disable them on our sites for an extra layer of protection.

In this article, we’ll walk you through how to disable login hints in WordPress to help you make your website more secure.

What Are Login Hints in WordPress Login Error Messages?

Whenever someone tries to log into your site using the wrong username or password, WordPress will show an error message on the login screen.

If this person typed in the wrong username or email address, then WordPress will show the following error: ‘The username is not registered on this site. If you are unsure of your username, try your email address instead.’

This may be helpful for genuine users, but it also lets any hackers know that they are typing in the wrong username.

Entering the correct username but an incorrect password triggers the error: ‘The password you entered for the username is incorrect. Lost your password?’

This confirms a correct username guess to potential attackers.

If someone manages to guess your username, the error message will let them know they’re on the right track. That means only your password stands in the way of them getting into your account.

WordPress website owners can also log into their site using an email address instead of their username. This means that a hacker could type in different email addresses to try and figure out which address you’re using for your WordPress account.

As soon as the hacker guesses the right email address, WordPress will switch to the ‘The password you entered for the username is incorrect’ error.

To protect your WordPress blog or site against hackers, you should always use a unique username and a strong password for your account.

If you’ve added other WordPress users or authors to your site, then you may also want to use a WordPress plugin to force your users to create a strong password.

While these steps are a great start, the login hints can help hackers break into your site. With that in mind, let’s look at how you can hide the login hints in WordPress login error messages.

Hiding Login Hints in WordPress

The easiest way to disable login hints in WordPress login error messages is by pasting some code into WordPress. While we normally don’t suggest this for beginners, WPCode makes it easy for anyone to add code to their WordPress website.

You can add the following code snippet to the bottom of your site’s functions.php file, but doing so could cause your site to break.

In our experience, WPCode is super beginner-friendly and ensures that even if you make a mistake while adding custom code, your site remains accessible. To learn more, see our detailed WPCode review.

First, you need to install and activate the free WPCode plugin. For detailed instructions, you can see our guide on how to install a WordPress plugin.

Upon activation, all you have to do is go to Code Snippets » +Add Snippet from your WordPress admin dashboard. Then, you’ll want to hover your mouse over ‘Add Your Custom Code’ and click ‘Use Snippet.’

After that, you simply need to name your new snippet and paste the following code into the ‘Code Preview’ area:

function no_wordpress_errors(){
  return 'Something is wrong!';
}
add_filter( 'login_errors', 'no_wordpress_errors' );

This code changes the default login page error to a custom message, such as ‘Something is wrong!’.

Also, this code tells WordPress to show a custom message instead of the default error. In the example code above, we’re using ‘Something is wrong!’ as our error message.

You can change this line to show any message that you want. For example, here we’re using ‘Something is wrong!’ as our error message:

 return 'Something is wrong!';

Be sure to select PHP from the ‘Code Type’ dropdown, and then you can toggle the switch from ‘Inactive’ to ‘Active’ and click on ‘Save Snippet.’

Once you’ve done that, it’s a good idea to test your new error message.

To do this test, simply head over to your website’s login page and type in the wrong username, password, or email. Then, go ahead and click on the ‘Log In’ button.

WordPress will now show your new error message without giving you any hints about what could be wrong.

Now, do note that while this code will disable login hints in WordPress, it won’t protect you from more advanced attempts or brute-force attacks.

The easiest way to prevent hackers from accessing your site is to use a WordPress security plugin like Cloudflare or WordFence.

Bonus Tip: Improving Your WordPress Login Security

Now that you know the importance of a strong username and password, let’s explore some additional ways to boost your login security. It’s important not only for you but also for anyone contributing to your blog, especially if multiple authors run it.

Here are some bonus tips to help keep your accounts even safer:

🔐 Enable Two-Factor Authentication (2FA): This adds an extra layer of security by requiring a second form of verification, like a text message code or a security question.

🔑 Use a Password Manager: These tools help you create and store complex passwords securely, so you don’t have to remember them all.

🔄 Update Your Password Regularly: Change your passwords every few months to minimize the risk of unauthorized access. It’s even better if you can force password updates for users.

🚫 Avoid Using Public Wi-Fi for Sensitive Logins: If possible, use a secure, private connection when logging into important accounts.

🛠️ Keep Your Software Updated: Regular updates can protect you from security vulnerabilities that attackers may exploit.

On top of everything, you might want to limit login attempts on your WordPress site.

During a brute-force attack, hackers use automated software to repeatedly guess passwords due to the platform’s default allowance for unlimited login attempts.

Limiting failed login attempts, such as temporarily locking out users after 5 unsuccessful tries, significantly reduces the risk of unauthorized access from brute force attacks.
