Your League of Legends username is how other players know you in-game. Whether you picked a name years ago that no longer fits, want something that better matches your playstyle, or just feel like a change, Riot Games lets you rename your account. Understanding the process, costs, and any restrictions helps you make the switch smoothly without losing progress or running into unexpected issues.
The articles here walk through how the renaming system works, what happens to your old name, whether name changes cost Riot Points or are sometimes free, and what names you cannot use. You'll also find information about changing your display name versus your account name, and what to do if you run into problems during the process.
