How to Limit Login Attempts in WordPress? [Should You Do It?]

WordPress powers over 40% of all websites on the internet, making it one of the most popular content management systems globally. However, with popularity comes risk. Hackers often target WordPress sites using brute-force attacks, where they repeatedly attempt to guess login credentials. One effective way to protect your site from these attacks is to limit login attempts.

Why Should You Limit Login Attempts in WordPress?

By default, WordPress allows users to try logging in an unlimited number of times. This presents a serious security risk because it opens the door to brute-force attacks. Here’s why limiting login attempts is essential:

1. Prevent Brute Force Attacks

Brute force attacks use automated bots to try thousands of combinations of usernames and passwords. Limiting login attempts drastically reduces the chances of these attacks succeeding.

2. Reduce Server Load

Repeated login requests consume server resources. If bots target your login page constantly, it can lead to performance issues and even server crashes, especially on shared hosting.

3. Enhance Website Security

Limiting login attempts helps protect user accounts, especially admin accounts, from being compromised.

4. Deter Attackers

Hackers tend to move on when they encounter a protected login system. A site that limits login attempts signals strong security, making it a less appealing target.

How to Limit Login Attempts in WordPress

There are several ways to set up login attempt limits on a WordPress site. Let’s go through the most effective methods.

---

Method 1: Use a Security Plugin

The easiest and most beginner-friendly way to limit login attempts is by using a plugin. Here are some top-rated WordPress plugins that offer this functionality:

1. Limit Login Attempts Reloaded

This is a lightweight and widely used plugin specifically built for this purpose.

Features:

• Limit login retries per IP

• Notify admins on multiple failed attempts

• Lockout time and retry delay options

• GDPR compliant

How to use it:

• Install and activate the plugin from the WordPress Plugin Repository.

• Go to Settings > Limit Login Attempts.

• Customize the number of allowed attempts, lockout duration, and email notifications.

2. Wordfence Security

While Wordfence is primarily known as a firewall and malware scanner, it also includes login attempt limiting features.

How to configure it:

• After installation, go to Wordfence > All Options.

• Scroll to the Brute Force Protection section.

• Set rules for “Lock out after how many login failures” and “Lock out after how many forgot password attempts”.

3. iThemes Security

Another all-in-one security plugin that provides an intuitive interface and powerful features.

Steps:

• Go to Security > Settings > Brute Force Protection.

• Enable local brute force protection.

• Customize lockout thresholds and durations.

Method 2: Use Functions in Your Theme’s functions.php File

If you prefer a code-based solution or don’t want to install extra plugins, you can manually limit login attempts using custom PHP code. Here’s a basic example:

php

Sao chépChỉnh sửa

function custom_login_failed_attempts() {
$ip = $_SERVER['REMOTE_ADDR'];
$attempts = get_transient('failed_login_' . $ip);if ($attempts >= 5) {
wp_die(‘You have been temporarily locked out due to too many failed login attempts.’);
}
}
add_action(‘wp_login_failed’, ‘custom_login_failed_attempts’);function custom_login_lockout($username) {
$ip = $_SERVER[‘REMOTE_ADDR’];
$attempts = get_transient(‘failed_login_’ . $ip);
$attempts++;
set_transient(‘failed_login_’ . $ip, $attempts, 300); // lock for 5 minutes
}
add_action(‘wp_login_failed’, ‘custom_login_lockout’);

⚠️ Warning: Editing theme files directly can break your site. Always use a child theme or a site-specific plugin and test changes on a staging site first.

Method 3: Enable Login Attempt Limits Through Hosting or Firewall

Some managed WordPress hosting providers (like Kinsta, WP Engine, or SiteGround) already implement login protection by default. They often include:

• IP blocking after repeated failed logins

• Integration with server-level firewalls

• Activity logs and alerts

Also, cloud-based firewalls like Cloudflare or Sucuri offer brute force protection and rate-limiting rules. If you’re using these services, you may already be protected without needing a plugin.

Best Practices When Limiting Login Attempts

Setting up a limit is just one part of the solution. Here are additional best practices to maximize your site’s security:

✅ Use Strong Passwords

Encourage all users to use strong, unique passwords with a mix of characters.

✅ Enable Two-Factor Authentication (2FA)

Even if someone guesses your password, they won’t be able to log in without the second factor.

✅ Rename the Login URL

Using a plugin like WPS Hide Login to change /wp-login.php to something custom makes it harder for bots to target your site.

✅ Monitor Failed Login Logs

Always monitor login logs and suspicious IPs. Plugins like Wordfence or iThemes Security offer dashboards to help with this.

✅ Whitelist IPs

If you’re the only person accessing the admin area, whitelist your IP to block all others.

Should You Limit Login Attempts?

Yes — limiting login attempts is a smart and essential step for any WordPress site. It’s a low-cost, high-impact security measure that can prevent common attacks and reduce risk.

That said, it’s not a complete solution by itself. Login attempt limits work best when combined with:

• Firewall protection

• Secure hosting

• Frequent updates

• Regular backups

• User education

If your website handles sensitive data, membership logins, or has high traffic, investing in a full-featured security plugin or premium firewall service is highly recommended.

Conclusion

In today’s digital landscape, WordPress websites face numerous threats, with brute force attacks being among the most common. Limiting login attempts is one of the simplest and most effective steps you can take to harden your website.

Whether you use a dedicated plugin like Limit Login Attempts Reloaded, a comprehensive tool like Wordfence, or a manual coding solution, the important part is that you take action.

Your site’s security is only as strong as its weakest link — don’t let your login page be that weakness.
