How to Limit Login Attempts in WordPress | Should You?

WordPress is the most popular content management system, powering over 40% of websites. However, its popularity also makes WordPress sites a target for attacks. One common type of attack is brute-force attempts to guess login credentials. To protect your site, it’s essential to limit login attempts. Let’s begin the comprehensive guide on How to Limit Login Attempts in WordPress.

Should You Limit Login Attempts in WordPress?

Yes, limiting login attempts in WordPress is highly recommended for security reasons.

Limiting login attempts in WordPress is a crucial security measure to protect your website from brute-force attacks. Here are some reasons why you should limit login attempts and how to implement this feature:

Why You Should Limit Login Attempts

1. Prevent Brute Force Attacks

Brute force attacks involve repeated attempts to guess a user’s password. By limiting login attempts, you can significantly reduce the likelihood of an attacker successfully gaining access to your website.

2. Enhance Website Security

Limiting login attempts adds an extra layer of security to your WordPress site. This measure ensures that even if someone tries to break in, they have a limited number of tries before being locked out.

3. Reduce Server Load

Continuous login attempts can put a strain on your server, slowing down your website. By limiting the number of login attempts, you can mitigate this issue and maintain optimal site performance.

4. Protect User Accounts

If your website allows user registrations, limiting login attempts can help protect your users’ accounts from unauthorized access. This measure reassures your users that their data is secure.

Default WordPress Login Settings

In a standard WordPress installation, the default login settings are relatively permissive. For example:

• Unlimited Login Attempts: WordPress allows users to make an unlimited number of login attempts by default. This means that attackers can keep trying different username and password combinations indefinitely.
• No Delay Between Login Attempts: No delay or rate is limiting between login attempts, making it easier for attackers to conduct brute-force attacks.
• No Lockout or IP Blocking: WordPress does not automatically lock out users or block IP addresses after a certain number of failed login attempts.

Importance of Login Attempt Limits

Limiting login attempts is crucial for several reasons:

1. Protection Against Brute Force Attacks: Attackers use automated tools to guess login credentials. Limiting attempts makes it harder for them to succeed.
2. Preventing Credential Stuffing: Attackers use credentials obtained from data breaches on other sites to gain access to WordPress sites. Limiting attempts reduces the risk of successful attacks.
3. Mitigating DDoS Attacks: Some attacks target the login page with a large number of login attempts, overwhelming the site. Limiting attempts helps minimize the impact of such attacks.
4. Protection Against User Enumeration: WordPress provides different error messages for incorrect usernames and passwords, allowing attackers to determine valid usernames. Limiting attempts reduces this risk.
