A client recently asked me if having an “admin” user in WordPress is bad and, if so, why.
It may seem harmless…but it’s not!
If you’ve ever installed WordPress the quick and easy way, there’s a good chance the default username “admin” was suggested or automatically created for you.
Using “admin” as your WordPress username is one of the most common and avoidable security mistakes website owners make. As someone who maintains WordPress sites professionally, I see this happening more often than I should.
It Makes Brute-Force Attacks Easier
Most WordPress login attacks are automated.
Bots constantly scan the web looking for WordPress login pages such as /wp-admin and /wp-login.php. When they find one, they start guessing passwords.
A login requires two pieces of information: a username and a password.
If your username is “admin,” the attacker already has 50% of what they need. Instead of guessing both fields, they only need to guess the password. That significantly reduces the complexity of the attack.
“Admin” Is The First Username Hackers Try
Attack scripts are not random. They are strategic. The first usernames typically tested are admin, administrator, test, and user.
If your username is “admin,” you are essentially making it easier for automated scripts to target your login page. Even if you have a strong password, you are increasing your exposure unnecessarily.
It Increases Log Spam and Server Load
When bots repeatedly attempt logins using “admin,” it can fill your logs with failed attempts, increase server resource usage, slow down smaller hosting environments, and create unnecessary noise in security reports.
On high-traffic or lower-tier hosting plans, this activity can negatively impact performance.
It’s an Outdated Practice
Years ago, WordPress defaulted to the username “admin” during installation. That changed with WordPress 3.0 in 2010.
Modern WordPress installations require you to choose a username. If you are still using “admin,” it likely means the site is older, was migrated from legacy hosting, or was set up without current security best practices in mind. That is usually a signal to review other security settings as well.
Changing It Is Simple and Worth the Effort
You cannot directly rename a WordPress username, but the solution is straightforward.
First, create a new administrator account with a unique username. Then log out and back in with the new account. After confirming everything works, delete the old “admin” user and attribute all content to your new user.
What You Should Use Instead
Choose a username that is not your business name, domain name, email address, or something publicly displayed.
Pair that with a strong password of at least 12-16 characters, consider adding two-factor authentication, use login attempt limiting, and protect your login with Cloudflare Managed Challenge.
Security works best in layers.
Final Thoughts
Using “admin” as your WordPress username will not automatically result in a hacked site. However, it lowers the barrier to entry for attackers, and that alone makes it worth avoiding.
WordPress powers a significant portion of the web, which makes it a common target. Small improvements, like choosing a non-obvious username, meaningfully reduces risk.
If you manage one or more WordPress sites, this should be part of your standard launch checklist. Security is not about paranoia. It is about removing easy opportunities for attackers. If you’re unsure about the state of your site security, contact us today and we’ll be glad to help!
