You change your login username through the Riot Games account website, not inside the game client
Your League of Legends login username — the name you type into the sign-in screen — is separate from your in-game summoner name. The login username is tied to your Riot Games account and lives at account.riotgames.com. You cannot change it from the League client itself. The process takes about five minutes and requires access to the email address linked to your account.
Riot Games allows one login username change per account, and it becomes permanent. You cannot revert to an old username or change it again later, so choose carefully before you confirm.
Key Takeaways
- Log into account.riotgames.com with your current login credentials to reach the username change tool.
- You get one permanent change per account, so the new username cannot be undone or swapped back.
- The new username must be between 3 and 16 characters, contain only letters, numbers, hyphens, and underscores, and not already be in use by another Riot account.
- After you change your login username, you use the new name to sign into League of Legends and all other Riot games on that account.
- Your summoner name (the name visible in-game) stays the same unless you change it separately through the League client using Riot Points.
Step-by-step: changing your login username
Go to account.riotgames.com and sign in with your current login username and password. If you have two-factor authentication enabled, you will need to enter the code from your authenticator app or receive it by email.
Once you are logged in, look for "Username" in the left sidebar menu. Click it. You will see your current username displayed, and below it a button that says "Change Username" or "Edit". Click that button.
Type your new username into the text field. Riot Games will tell you when ready if the name is already taken or breaks the character rules. The name must be 3 to 16 characters long and can only contain letters (a–z, A–Z), numbers (0–9), hyphens (-), and underscores (_). No spaces, no special characters like periods or apostrophes.
Review the new username one more time. Riot will ask you to confirm that you understand this change is permanent and cannot be undone. Click the final confirm button. The change takes effect when ready, and you will be signed out of the website.
What happens after you change your login username
You now sign into League of Legends using your new login username, not the old one. The same new username works for all Riot Games titles on that account — Valorant, Teamfight Tactics, League of Legends, and any others tied to the same Riot account.
Your summoner name (the name that appears above your character in-game) does not change automatically. If you want a different summoner name, you change that separately inside the League client by clicking your profile icon, selecting "Summoner", and choosing "Change Name". That costs Riot Points (the paid currency) and can be done multiple times.
If you are signed into the League client when you change your login username, you will be logged out. Close and reopen the client, then sign in with your new username.
Reasons your new username might be rejected
Riot Games rejects usernames that are already in use by another account. If you see "This username is unavailable", someone else has claimed it. Try a variation — add a number, use an underscore, or pick a different name entirely.
Usernames that contain only numbers, or that look like email addresses, are also rejected. Riot requires at least one letter in your username. Names that are flagged as offensive or that impersonate Riot staff or pro players will be rejected as well.
If you see an error message that does not match these reasons, try again in a few minutes. Occasionally the website has temporary issues. If the problem persists, contact Riot Games support through the help portal at support.riotgames.com.
If you forgot your current login username
You cannot change a username if you cannot sign in. Go to the League of Legends sign-in page and click "Forgot your username?". Riot will ask for the email address linked to your account and send you a message with your current username.
If you no longer have access to that email address, you will need to contact Riot Games support. They can verify your identity through security questions or other account details and help you regain access. This process takes longer than a straightforward username change, so reach out to support.riotgames.com as soon as you realize you cannot sign in.
The difference between login username and summoner name
Your login username is what you type at the sign-in screen. It is tied to your Riot Games account and is the same across all Riot games. Your summoner name is the name that displays in League of Legends when you play — it is what other players see in chat and on the scoreboard.
You can change your summoner name as many times as you want (for a fee in Riot Points), but you get only one free permanent change to your login username. Many players keep their login username private and use a different summoner name for visibility in-game.
Frequently Asked Questions
Can I change my login username more than once?
No. Riot Games allows one permanent username change per account. After you confirm the change, you cannot revert it or change it again. Choose your new username carefully before you submit.
Will changing my login username affect my rank or match history?
No. Your rank, match history, and all account progress stay exactly the same. Only the name you use to sign in changes. Your summoner name in-game remains unchanged unless you alter it separately.
What if someone else has the username I want?
You cannot use a username that is already claimed by another Riot account. Try a slight variation — add numbers, use underscores or hyphens, or choose a different name. Riot does not release old usernames when accounts are deleted.
Do I need to change my password when I change my username?
No. Your password and username are separate. Changing one does not affect the other. However, if you are concerned about account security, you can change your password anytime from the account.riotgames.com security settings.
How long does the username change take to show up?
The change is when ready. You can sign out and sign back in with your new username right away. If you are already signed into the League client, log out and log back in to see the change reflected.
