Your Steam username is how other players know you in the community. Whether you picked something you've outgrown, want a fresh start, or straightforward prefer a different name, Steam lets you change it whenever you want. This category covers how the username system works and what happens when you make a change.
The articles here answer practical questions: how to change your name through your account settings, whether other players will see your old username in their friends list, what restrictions exist on how often you can change it, and how to handle situations where your desired name is already taken by another account.
