Here’s How Hackers Can Find your WordPress Username

So you’ve taken pains to hide your WordPress login and admin screens from hackers. You’ve changed your default usernames, and removed all mention of them from your theme. You’re safe right? There’s no way that hackers can find your login pages, let alone your usernames. Wrong! Unless you take precautions, here’s how hackers can find your WordPress username with ease. And not just yours – those of everyone on the site.

Using /?author=1 Query Parameter

One day, I had just set up a new blog and thought I’d hidden my admin areas pretty well. To my surprise, my security plugins started sending me lockout notices. This means that not only were hackers able to find my login page, they were able to guess my WordPress username as well! I opened up my raw access logs in cPanel, and found this:


Apparently, hackers can find your username in WordPress by appending the query /?author=1! You can see in the screenshot above, that my server immediately returned the author page – which of course, revealed the username. So forget about making your username difficult to guess. It’s right out there in the open!

Here’s how it looks. First, type in your blog name and type /?author=1 after the URL like this:


This will immediately redirect to your author page like so:

Hackers can find your WordPress Username

Some experts claim that exposing WordPress usernames is not a security risk. According to them, creating a strong password and using two factor authentication is the right way to go about it. But I say there’s nothing wrong in hiding as much information as possible from hackers. Maybe if someone is truly determined to know my username, they can. But that doesn’t mean I have to make it easy for them! I want potential attackers to work to break into my site. Hopefully, this will deter 90% of them.

If hackers don’t know your username, they won’t spam your site trying to guess your password. This means less load on your server. I’ve been brought down once before by hackers DDoS’ing my login page. I don’t want to risk that again.

So how do we close this loophole? There are two ways to prevent WordPress from revealing your author name via the parameter hack.

Method 1: Modifying .htaccess

This is my preferred technique because it’s much faster than the alternative. By creating a simple .htaccess rule, you can immediately block all attempts to access your WordPress username via the ?author parameter. If you have access to it, open the hidden “.htacces” file in the root directory of your WordPress installation, and paste in the following code at the end:

RewriteEngine On
RewriteCond %{REQUEST_URI} !^/wp-admin [NC]
RewriteCond %{QUERY_STRING} author=\d
RewriteRule ^ /? [L,R=301]

Here’s what the WordPress .htaccess looks with the above code added on:


These rules check to see that you’re not in the admin area, and whether or not someone is attempting to access the “author” query parameter. If the conditions are met, it simply redirects back to the WordPress homepage. Problem solved!

After implementing this code in my .htaccess, the raw access log entry looks like this:


So even though someone has attempted to find out my username by typing “/?author=1”, the server smartly sends back the homepage of my blog. This is an extremely fast process, and hardly uses any server resources. So it’s the efficient and preferred way.

But what if you can’t make changes to .htaccess? Then the second method is the one for you.

Method 2: Adding a Code Snippet to WordPress

The second method is to add a code snippet to WordPress that accomplishes the same. If you don’t know how, read my earlier step by step tutorial on how to do this. Here is the code you need to paste into your custom plugin or functions.php:

function redirect_to_home_if_author_parameter() {

	$is_author_set = get_query_var( 'author', '' );
	if ( $is_author_set != '' && !is_admin()) {
		wp_redirect( home_url(), 301 );
add_action( 'template_redirect', 'redirect_to_home_if_author_parameter' );

Like the .htaccess code, this does exactly the same thing. It checks to see if you’re not in the admin area, and whether or not someone is trying to access the author name via the “?author” parameter. If so, it redirects back to the home page.

The difference is that this executes at the WordPress level, and is therefore slightly more inefficient than the first method. But if you don’t have access to .htaccess, it’s the only other way. Checking your access logs will reveal the exact same thing regardless of which method you choose.

So while some might deny that revealing usernames is a security threat, my principle is that the harder you make it for someone to snoop around your website, the better. And if you want to prevent brute force attacks, and to prevent hackers from finding your WordPress username, one of these two snippets of code will do the trick!


  1. Thank you for writing about this topic. I think I might have found another option:

    Install the plugin “Edit Author Slug”, then enter a new author slug (different to your username) in your profile. You can also set a 301 Redirect from the old version to the new one by entering the following in .htaccess :

    RewriteEngine On
    Redirect 301 /author/username-that-you-want-hidden/

    With this method, the author’s archive page is still usable.

    Thanks for that!!! So many and “little” things you have to think about


  3. Hey! I now thks is somewhat off topic but I was wondering if you knew where I could find a casptcha plugin for
    myy coomment form? I’m using the same bloog platform as yours and I’m having
    difficulty finding one? Thanks a lot!


  4. Thanks for this, great solution . I was searching for a solution because I have several hacking attempts doing exactly this. .htaccess solution worked a treat I really wanted to do this server side. 🙂
