Where to find the username setting in TLauncher
Open TLauncher and look at the top right corner of the main window. You will see a profile icon or your current username displayed there. Click on it to open a dropdown menu. Select "Skins and capes" or "Profile" depending on your TLauncher version — the exact label varies, but it will be the option that takes you to account settings.
Once you are in the profile section, look for a field labeled "Username" or "Nickname". This is where your current name appears. The field may be grayed out or editable depending on whether TLauncher recognizes your account as linked to a Microsoft or Mojang account.
Key Takeaways
- TLauncher stores your username in the profile settings, accessible from the icon in the top right corner of the main window.
- If your account is linked to Microsoft or Mojang, you cannot change the username inside TLauncher — you must change it through the official Microsoft account portal.
- Offline mode accounts (not linked to any service) allow you to edit the username field directly in TLauncher.
- Changes to your username take effect the next time you launch a game, not when ready.
Changing the username for offline accounts
If you are playing in offline mode and your account is not linked to Microsoft or Mojang, the username field will be editable. Click directly on the text in the username field, clear it, and type your new name. TLauncher usernames can contain letters, numbers, and underscores, and must be between 3 and 16 characters long.
After you type the new name, click outside the field or press Enter to save the change. You do not need to restart TLauncher, but the new username will only appear in-game the next time you launch Minecraft.
Changing the username for linked Microsoft accounts
If your TLauncher account is connected to a Microsoft account, the username field will be locked and you cannot edit it from within TLauncher. Instead, you must change your username through the official Microsoft account website. Go to account.microsoft.com, sign in with your Microsoft credentials, and navigate to your profile or account settings.
Look for an option labeled "Manage your Microsoft account" or "Edit profile". From there, find the Minecraft profile section and select the option to change your in-game name. Microsoft allows one free name change every 30 days; additional changes within that period may require payment. After you change it on Microsoft's site, TLauncher will reflect the new name the next time you log in.
Changing the username for Mojang-linked accounts
Accounts linked to a Mojang account follow a similar process. Visit launcher.mojang.com or minecraft.net, sign in with your Mojang credentials, and look for account settings or profile management. The username field there will allow you to change your in-game name, subject to Mojang's rules about name availability and change frequency.
Once you have changed it on Mojang's site, log out of TLauncher completely and log back in. The new username should appear in your TLauncher profile and in-game on your next launch.
What happens if your desired username is already taken
If the username you want is already in use, TLauncher or the linked service will show an error message when you try to save. For offline accounts, straightforward choose a different name and try again. For Microsoft or Mojang accounts, you will need to pick an alternative name, because you cannot reserve a username or join a waitlist — the name is either available or it is not.
Some older or inactive accounts may hold usernames that are no longer in use. Microsoft and Mojang periodically release names from abandoned accounts, but there is no way to request a specific name or know when it might become available.
Troubleshooting username changes that do not appear
If you changed your username but it still shows the old name in TLauncher or in-game, close TLauncher completely and reopen it. Log out and log back in to force a refresh of your account data. This usually takes less than a minute and will sync the new username from the linked service.
If the old name persists after logging back in, check that you actually saved the change on the Microsoft or Mojang website — sometimes the save button is straightforward to miss. You can also verify the change was saved by visiting the account website again and checking the profile section. If the website shows the new name but TLauncher does not, wait a few minutes and try logging out and back in again, as the change may not have propagated yet.
Frequently Asked Questions
Can I change my username back to what it was before?
Yes, but only if the old name is still available. If someone else has claimed it, you cannot use it again. For Microsoft accounts, you get one free name change per 30 days, so if you change it and then change it back within that window, the second change may cost money depending on your region.
Does changing my username affect my world saves or achievements?
No. Your worlds, skins, and game progress are tied to your account, not your username. Changing the name does not delete anything or reset your progress — only the name that appears to other players changes.
What if I forgot my password and cannot access the linked account?
You will need to recover your Microsoft or Mojang account first. Visit the password recovery page on the service's website, verify your identity, and reset your password. Once you can log in again, you can change your username. TLauncher itself cannot reset your password or change your username without access to the linked account.
Can I use special characters or spaces in my username?
No. Minecraft usernames accept only letters (A–Z, a–z), numbers (0–9), and underscores (_). Spaces, hyphens, and other symbols are not allowed. If you try to use them, TLauncher or the linked service will reject the change.
