How to Limit Automated Login Attempts on WordPress

If you have a standard WordPress installation on your site then chances are that you’re getting hundreds (maybe even thousands) of malicious attacks on it per month. And one of the most common forms of WordPress attacks is, in essence, quite simple – a brute force attack.

Instead of finding vulnerabilities in the core WordPress software, hackers attempting a brute force attack simply try millions of username and password combinations until they gain access to your site. They can do this because, by default, WordPress allows users to punch in their login credentials as many times as they need to.

With this in mind, in this post, we’ll show you how you can deal with potential brute force attacks by limiting automated login attempts on your WordPress login page. We’ll also run the rule over a few plugin solutions which seek to address this problem.

A Note on Automated Brute Force Attacks on the WordPress Admin

Simply put, brute force attacks are when hackers or bots try out many different username and password combinations in hopes of ultimately gaining access to your site. According to the Sucuri blog, brute force attacks are one of the leading reasons why WordPress websites are compromised.

Even though WordPress regularly releases security updates, the number of brute force attacks on the WordPress admin continues to grow. This is mainly because standard installations of WordPress allow anyone to access the login page easily and try out as many username and password combinations as they’d like.

This doesn’t mean that there is a person sitting behind a computer furiously typing away at their keyboard in hopes of landing on the correct combination. In fact, all they have to do is write an automatic script that generates millions of combinations in minutes and let it run.

Why It's a Good Idea to Limit Automated Login Attempts

The WordPress admin is incredibly easy to access. All you have to do is append wp-admin (or wp-login.php) to your site’s URL and you’ll be redirected to the standard login page. This is what makes standard WordPress sites an easy target to brute force attacks.

One way to deal with this problem is to hide your WordPress site’s login page. If the hackers can’t access the login page, they won’t be able to gain access to the WordPress admin. And although this is a popular security measure, not everyone is in a position to implement it. Here a few reasons why:

  • Membership sites. If you’re running a membership website then your users should be able to access your site’s login page easily. Hiding the WordPress login page could compromise your user base.
  • E-commerce platforms. Most online stores allow users to create an account with them to simplify the checkout process and get exclusive access to promotions and reward points. If prospective customers have difficulty logging into your e-commerce site every time then they may stop buying from you.
  • Online forums. Website owners who operate online forums need to make sure their users can login with ease (and stay logged in for long periods of time). And if your forum’s login page is hidden then you could risk losing both users and traffic.

Thankfully, when it comes to minimizing the number of brute force attack attempts on the WordPress admin, there’s more than one way to deal with the problem. Case in point: limiting automated login attempts.

Regardless of how many people access your WordPress site regularly, limiting automated login attempts is an elegantly simple yet super-effective way to reduce the number of attacks your site sees. The key concept behind it is simple: when a user (or bot) enters more than a pre-defined number of incorrect username and password combinations, they cannot try again for a specified period of time.
