Change your name through the Minecraft Launcher

Your player name in Minecraft is the username that appears above your character's head and in the chat. To change it, you open the official Minecraft Launcher, log in with your Microsoft account, and edit the name directly in the launcher before you start the game. The change takes effect the next time you join a world or server.

This is the only way to change your name in the actual game files. Minecraft does not have a name-change option inside the game itself — you must do it from the launcher. If you are playing on a server or realm, the server owner may have set rules about how often you can change your name, but the launcher change itself has no built-in limit.

Key Takeaways

  • Open the Minecraft Launcher, log in with your Microsoft account, and click the pencil icon next to your current name to edit it.
  • Your new name appears in the launcher when ready, but the change takes effect in-game the next time you join a world or server.
  • You can change your name as often as you want through the launcher, though some servers may restrict how frequently players can change names.
  • If you are playing offline or on a cracked server, you may be able to change your name through launcher settings, but the method varies by launcher type.

Step-by-step: editing your name in the launcher

Start by opening the Minecraft Launcher. If you have not installed it yet, read it from the official Minecraft website. Once it opens, you will see a login screen if you are not already signed in. Enter your Microsoft account email and password, then click Sign In.

After you log in, look at the top left of the launcher window. You will see your current player name displayed there. Next to it is a small pencil icon. Click that pencil icon to enter edit mode. The name field will become editable — the text will highlight and you can now type your new name. Type the name you want, then press Enter or click outside the text field to save it. The launcher will show your new name when ready.

Now start the game normally by clicking the Play button. The next time you load into a world or join a server, your new name will appear above your character. Other players will see the new name in chat and above your head. If you are playing a world you created before the change, your old name may still appear on old blocks you placed, but all new activity will show your new name.

What names are allowed and what happens if you pick one that is not

Minecraft accepts most names between 3 and 16 characters long. You can use letters, numbers, and underscores. You cannot use spaces, special characters like hyphens or periods, or characters from other languages. If you try to save a name that breaks these rules, the launcher will not let you confirm the change — the Save button will stay grayed out or the field will show an error.

If your chosen name is already taken by another player, Minecraft will still let you use it. Multiple players can have the same name in the game itself, though each account has a unique ID behind the scenes. This can be confusing on servers where many people see the same name, but it is allowed. Some servers use plugins to prevent duplicate names, but that is a server choice, not a Minecraft rule.

Changing your name on servers and realms

If you play on a Minecraft Realm (a world hosted by Minecraft), your name change takes effect when ready for everyone in that realm. You do not need to do anything special — just change it in the launcher and rejoin the realm.

On third-party servers, the change also takes effect when you rejoin, but some servers have their own name-change rules. A server owner might set a cooldown so players cannot change their name more than once per week, or they might disable name changes entirely. If a server has this rule, you will see a message when you try to join with a new name. You would need to wait out the cooldown or contact the server owner to change it back. The launcher change itself is permanent — you cannot undo it from inside the game.

If you cannot find the pencil icon or your launcher looks different

The pencil icon appears only if you are logged in with a Microsoft account. If you are still using an old Mojang account (accounts created before Microsoft took over Minecraft), you may see a different launcher layout. You can still change your name, but the button location may differ. Look for a Settings or Profile option in the launcher menu, then find the name field there.

If you are using a third-party launcher like MultiMC or Prism Launcher because you play modded Minecraft, the name-change process is different. These launchers have their own settings. Open the launcher, find the instance or profile you want to change, right-click it and select Edit, then look for a Player Name field. The exact steps vary by launcher, so check that launcher's documentation if you cannot find the field.

What happens to your old name and whether you can get it back

When you change your name in the Minecraft Launcher, your old name becomes available for someone else to use. You can change back to your old name anytime by editing the launcher again, but if another player has claimed it in the meantime, you cannot use it until they change theirs. Minecraft does not reserve old names for their original owners.

Your player UUID — a unique identifier assigned to your account — never changes. This is what Minecraft uses to track your progress, items, and achievements. Other players cannot see your UUID, but servers use it to know it is really you even if you change your name ten times. Your worlds, items, and progress all stay with your account no matter how many times you rename.

Troubleshooting: your name did not change in-game

If you changed your name in the launcher but it still shows your old name in the game, the most common reason is that you did not fully close and restart the game. Close Minecraft completely, wait a few seconds, then open it again from the launcher. The new name should appear when you load in.

If the name still has not changed after a full restart, log out of the launcher completely, then log back in. This forces the launcher to refresh your account information. After you log back in, check that the launcher shows your new name, then start the game again. If you are on a server and the name still shows as old, ask the server owner whether they have name-change restrictions or caching that delays the update.

Frequently Asked Questions

Can I change my name to something someone else is already using?

Yes. Minecraft allows multiple players to have the same name. Each account has a unique ID behind the scenes, so the game knows which player is which even if two people share a name. Some servers use plugins to prevent duplicate names, but the base game does not.

Will changing my name affect my worlds or items?

No. Your worlds, items, and progress are tied to your account ID, not your name. You can change your name as many times as you want and keep everything. Old blocks you placed before the name change will still show your old name, but that is just display — you still own them.

How long does it take for my new name to show up?

The name changes in the launcher when ready when you save it. In-game, it takes effect the next time you load a world or rejoin a server. You do not need to wait — just close and restart the game.

What if I change my name and then want to change it back?

You can change your name back anytime through the launcher using the same pencil icon. If someone else has claimed your old name in the meantime, you cannot use it until they change theirs. Otherwise, you can switch back and forth as much as you want.

Does changing my name cost money?

No. Changing your player name in Minecraft is free and unlimited. You can do it as many times as you want through the launcher at no cost.
