Securing your WordPress website raises a significant question: Is it a good idea to change the default WordPress admin username? The general consensus among cybersecurity experts has been that changing the default admin username in WordPress can contribute to enhancing security. The idea is to make it more challenging for attackers to guess usernames, as the default "admin" is often targeted in brute-force attacks. In this article, we'll tackle this issue explore whether renaming your admin username is a smart move for safeguarding your website.

How Do Hackers Find My WordPress Admin Username?

Hackers have smart ways to find admin usernames by exploiting vulnerabilities. One common trick is checking blog posts. If you use the default "admin" username and publish posts, hackers can easily spot it in the author details. This simple act of posting becomes a road map for them, revealing the admin username and giving them an easy way into the site.

Another method is the /wp-json/wp/v2/users JSON file. By adding this to the end of a website's domain, you get an unfiltered list of users. It's like a secret file that exposes user details, making the admin username a prime target. In this hidden archive, hackers can study usernames so they can perform brute force attacks. For website admins aiming to secure their sites, grasping these subtle hacker moves is crucial to effectively strengthen their WordPress defenses.

Should I Change My WordPress Admin Username?

Yes! We not only suggest changing your WordPress admin username, but we also advise implementing the following updates on your website. Prior to making these changes, it's essential to consult with an IT professional or web developer to ensure the integrity of your website remains intact and doesn't encounter any disruptions.

Create admin alias

Create an alias for your admin account that will be used in your blogs posts instead of the real admin user. Some familiarity with MySQL commands is necessary for this update.

Don't post with admin usernames

We don't recommend creating ANY posts under an admin user. Your site might have multiple admin users for various users. There are other user roles like editor, author, contributor that should be used for creating posts.
