Where to change your username

You change your Minecraft username through the official Minecraft Launcher, not through a separate website. Open the launcher, select your profile from the top left, then click "Skin customization" or look for account settings depending on your launcher version. The username field is where you enter your new name — it must be between 3 and 16 characters, use only letters, numbers, and underscores, and cannot be a name already taken by another player.

If you are using the newer Minecraft Launcher (the one that looks like a grid of game tiles), click your account name in the top right corner, then select "Settings" and look for "Profile" or "Account" options. Older launcher versions have the username field directly visible on the main screen. The exact location depends on which launcher version you have installed.

Key Takeaways

  • You change your username inside the Minecraft Launcher itself, in your account or profile settings, not on a website.
  • Your new username must be 3 to 16 characters long and can only contain letters, numbers, and underscores.
  • The name you choose cannot already belong to another player, and the launcher will tell you when ready if it is taken.
  • After you change your username, it takes effect the next time you log in and join a server or world.
  • You can change your username once every 30 days if you are using a Microsoft account linked to your launcher.

Step-by-step for the newer launcher

Open the Minecraft Launcher and look at the top right corner where your account name appears. Click on your account name or the gear icon next to it. A menu will drop down with options including "Settings," "Profile," or "Account" — the exact wording varies by launcher version. Select whichever option shows your account details.

Once you are in your account settings, look for a field labeled "Username" or "Player Name." Click in that field and delete your current name, then type your new username. Remember the rules: 3 to 16 characters, letters and numbers only (underscores are allowed), and no spaces. As soon as you type, the launcher usually shows you whether that name is available or already taken. If it is taken, you will see a red X or an error message. If it is available, you will see a green checkmark.

Click "Save" or "Done" to confirm the change. Close the settings window and return to the main launcher screen. Your new username takes effect the next time you log in and play — it will not change mid-game if you are already playing.

Step-by-step for the older launcher

If you are using the older Minecraft Launcher (the one with a simpler, more compact design), the username field is usually visible on the main screen without needing to dig into settings. Look for a text box labeled "Username" or "Player Name" near the top or middle of the launcher window. Click in that box and clear your current name.

Type your new username following the same rules: 3 to 16 characters, letters and numbers only, underscores allowed, no spaces. The launcher will show you right away whether the name is taken. Once you have entered a name that is available, look for a "Save," "OK," or "Done" button and click it. Your new username will be active the next time you launch the game.

What happens if your chosen name is already taken

If the launcher shows that your desired username is already in use, you will need to choose a different one. The launcher does not show you who owns the taken name or give you a waiting list option — you straightforward cannot use it. Try adding a number to the end of your preferred name, or use an underscore in the middle. For example, if "SkyWalker" is taken, you might try "SkyWalker42" or "Sky_Walker."

Keep in mind that Minecraft usernames are case-insensitive, meaning "skywalker," "SkyWalker," and "SKYWALKER" are all treated as the same name. If any variation of your desired name is taken, none of the variations will be available to you.

The 30-day waiting period between changes

If your Minecraft account is linked to a Microsoft account (which is the case for most players now), you can change your username once every 30 days. This means after you change your username, you must wait a full month before you can change it again. The launcher will show you a countdown timer telling you when you are may be able to access to change it next.

If you try to change your username before the 30 days are up, the launcher will display an error message with the exact date you can make your next change. This limit exists across all Minecraft accounts linked to the same Microsoft account, so if you have multiple Minecraft profiles, changing the username on one profile counts toward the 30-day limit for all of them.

What to do if the launcher will not let you change your username

If you see an error message when trying to change your username, the most common causes are: the name is already taken, you are within the 30-day waiting period, your internet connection dropped, or your launcher needs to be updated. First, check that your internet connection is stable and try again. If the error persists, close the launcher completely and reopen it.

If you are still blocked, check whether your Microsoft account is properly linked to your Minecraft profile. Go to account.microsoft.com, sign in, and look for your Minecraft profile in your account settings. If the profile is not linked or shows an error, you may need to unlink and relink it. You can also try uninstalling and reinstalling the Minecraft Launcher, though this is rarely necessary. If none of these steps work, the Minecraft support website has a contact form where you can describe the problem.

How your username change affects multiplayer and servers

When you change your username, it changes everywhere you play — single-player worlds, multiplayer servers, and Realms all see your new name. If you have a skin (the character appearance) set to your old username, it may not transfer automatically depending on how you set it up. Most skins are tied to your account rather than your username, so they usually stay with you. If your skin does disappear, you can set it again in the launcher's skin customization menu.

On multiplayer servers, your new username takes effect the next time you join. Other players will see your new name in the chat and player list. If you were on a server's ban list or whitelist under your old name, that does not automatically update — the server owner would need to manually change it if they want to keep you whitelisted or banned under your new name. Some servers track players by their account ID rather than username, so your history and permissions may stay intact even though your visible name changed.

Frequently Asked Questions

Can I change my username back to what it was before?

Yes, but only after 30 days have passed since your last change. You can change your username to any available name, including a previous username you used, as long as no one else has claimed it in the meantime. If someone else took your old name, you cannot use it again unless they change theirs first.

Does changing my username affect my game progress or achievements?

No. Your game progress, worlds, and achievements are tied to your account, not your username. Changing your username does not erase anything. When you load a single-player world after changing your username, you will see your new name in the world, but all your progress is still there.

What if I have a Minecraft account that is not linked to Microsoft?

Older Minecraft accounts that were never migrated to Microsoft accounts may have different username change rules. If you have a legacy account, you may be able to change your username more frequently or face different restrictions. Check the Minecraft launcher or the official Minecraft website for your specific account type, as the process and limits vary.

Will my friends still be able to find me after I change my username?

Yes. Your friends can find you by your new username in multiplayer servers and Realms. If you are playing on a server together, they will see your new name in the player list and chat. If you play on Realms, your new username appears there as well. The only place they might have trouble is if they wrote down your old username on paper or in a note — they will need to know your new name to search for you.

Can I use special characters or spaces in my username?

No. Minecraft usernames can only contain letters (A–Z, a–z), numbers (0–9), and underscores (_). You cannot use spaces, hyphens, periods, or any other special characters. The launcher will reject any name that contains characters outside this set.
