Your Fortnite username is how other players know you in matches and on your profile. Whether you picked something you've outgrown, want a fresh start, or straightforward prefer a different name, Epic Games lets you change it through your account settings. This process works the same way across PC, console, and mobile platforms—you make the change once in your account, and it updates everywhere you play.
The articles here walk you through finding the right menu, understanding any limits on how often you can change your name, and what happens to your progress and friends list when you do. You'll also learn what names the system won't allow and how to troubleshoot if your change doesn't go through.
