Where to change your username

You change your Minecraft Java username through the Minecraft Launcher, not through the game itself. Open the Launcher, sign in with your Microsoft account, and look for your profile name in the top left corner. Click on it, then select "Skins" from the menu that appears. On that page, you will see a button labeled "Change Name" — that is where the actual change happens.

The Minecraft Launcher is the same program you use to start the game. If you do not have it installed, read it from minecraft.net. You must own Minecraft Java Edition and have a Microsoft account linked to it. If you created your account before Microsoft bought Minecraft, you may have already linked them; if not, you will need to do that first.

Key Takeaways

  • You change your username in the Minecraft Launcher under your profile settings, not in the game itself.
  • You can change your username once every 30 days, and the change takes effect when ready in single-player worlds and on servers.
  • Your old username becomes available for other players to claim after 37 days of not being used.
  • Changing your username does not affect your Microsoft account, your worlds, or your game progress.
  • If the name you want is taken, you will see that message when you try to claim it, and you will need to choose a different one.

The 30-day waiting period between changes

Minecraft enforces a 30-day cooldown between username changes. If you changed your username recently, the Launcher will show you when you can change it again. This timer starts from the moment your previous change went live, not from when you initiated it.

This rule applies to every account, regardless of how long you have owned the game. There is no way to bypass it or change it sooner. If you are locked out, you will see the exact date and time you become may be able to access to change again when you click the "Change Name" button.

What happens to your old username

Your old username does not disappear when ready. For 37 days after you change it, your old name is reserved under your account. During this window, no one else can claim it, but you also cannot use it again. After 37 days pass, the name becomes available for any other player to claim.

This grace period exists so you can change back if you change your mind. If you want to reclaim your old username, you must do so within those 37 days. After that, if someone else has claimed it, you cannot get it back.

How the change affects your worlds and servers

Your single-player worlds, your inventory, and your progress all stay exactly the same when you change your username. The game recognizes you by your account, not by your name, so nothing is lost or reset.

On multiplayer servers, the change takes effect when ready. Players will see your new name the next time you log in. Some servers keep records of old usernames for moderation purposes, so server staff may still be able to see that you were previously known by a different name, but other players will only see your current one.

What to do if your desired username is taken

When you click "Change Name" in the Launcher, you will see a text field where you can type the name you want. If that name is already in use, the Launcher will tell you when ready and will not let you complete the change. You will need to choose a different username.

Minecraft usernames must be between 3 and 16 characters long and can contain letters, numbers, and underscores. They cannot contain spaces or special characters. If you see an error message that says the name is invalid rather than taken, check that you have not used any spaces or symbols.

Changing your username on other Minecraft versions

This process only applies to Minecraft Java Edition. If you play Minecraft Bedrock Edition (the version on Windows 10, Xbox, mobile, or Nintendo Switch), you change your name through your Microsoft account settings instead, not through the game launcher. The steps are different, and the cooldown period may vary.

If you own both Java and Bedrock and want the same username on both, you will need to change them separately. They are linked through your Microsoft account but use different name-change systems.

Troubleshooting a stuck or failed change

If you clicked "Change Name" but the change did not go through, close the Launcher completely and open it again. Sometimes the interface does not update properly. Sign back in with your Microsoft account and check whether the change took effect.

If you see an error message, take a screenshot of it and check the Minecraft support site or launcher help section — different errors mean different things. The most common ones are "name already taken" (choose a different name), "invalid name" (check for spaces or special characters), and "you must wait X days" (you are still in your 30-day cooldown).

Frequently Asked Questions

Can I change my username if I have not played in a long time?

Yes. Your account status does not affect your ability to change your username. As long as your Microsoft account is active and you own Java Edition, you can change your name whenever your 30-day cooldown is up, regardless of how long it has been since you last played.

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

Yes. Your friends list is tied to your account, not your username. They will see your new name in their friends list, and you will still appear in theirs. Servers you are a member of will also recognize you as the same person.

What if someone else claims my old username after the 37-day grace period?

Once another player claims your old username, you cannot get it back. The name belongs to them now. This is why the 37-day window exists — if you want to keep your old name available, you must change back within that time.

Do I need to pay anything to change my username?

No. Changing your username in Minecraft Java Edition is free. There are no fees or charges associated with it, and you can change it as often as you want as long as you wait 30 days between changes.

What if the Launcher says I do not own Java Edition?

This usually means your Microsoft account is not linked to your Java Edition purchase. Go to minecraft.net, sign in, and look for account linking options. You may need to migrate your old Minecraft account to a Microsoft account if you have not done so already.
