The fastest way to change your Java Minecraft username

To change your Java Minecraft username, you log into your Microsoft account on the Minecraft launcher, then visit the Microsoft account website and change your profile name there. The change takes effect the next time you launch the game. You do not need to buy anything or contact support — it is built into your account settings.

The username you see in-game is tied to your Microsoft account, not to Minecraft itself. When you change your Microsoft profile name, Java Edition picks up that change automatically. This is different from older Minecraft accounts that were not linked to Microsoft, which had different rules — but if you are playing Java Edition now, your account is already linked.

Key Takeaways

  • Your Java Minecraft username comes from your Microsoft account profile name, so you change it there, not in the Minecraft launcher.
  • You can change your username once every 30 days, and the change shows up in-game the next time you launch.
  • The change applies only to Java Edition — if you also play Bedrock Edition on Windows, that version uses a different name system.
  • Old skins and world saves stay with your account; changing your name does not delete them.

Step-by-step: changing your name through Microsoft

Start by opening a web browser and going to account.microsoft.com. Sign in with the email and password you use for Minecraft. Once you are logged in, look for "Your info" or "Profile" in the left menu — the exact wording changes, but it is always near the top.

Click on "Manage your Microsoft account" or "Edit profile". You will see a field labeled "Name" or "Display name" — this is what shows in Java Minecraft. Click the edit button (usually a pencil icon) next to your current name. Type your new username, then click "Save" or "Next". Microsoft will ask you to confirm the change; follow the prompts to finish.

The change takes effect when ready on the Microsoft side, but Java Edition does not see it until you close and reopen the launcher. Close Minecraft completely, then launch it again and log in. Your new name should appear in the launcher and in-game.

The 30-day waiting period between changes

Microsoft enforces a 30-day cooldown between username changes on the same account. If you change your name today, you cannot change it again for 30 days. This limit is per account, not per username — you cannot get around it by changing to a temporary name and then changing again.

If you try to change your name before 30 days have passed, Microsoft will show you the date when you can change it next. There is no way to speed this up or request an exception. Plan your username change carefully, because you will be stuck with it for a month.

What stays the same when you change your username

Your skins, worlds, and server history all stay attached to your account. Changing your name does not delete anything or reset your progress. Other players will see your new name the next time they load a world or server where you are present, but your UUID (the hidden identifier Minecraft uses internally) never changes.

If you have paid for Minecraft Realms or downloaded skins from the marketplace, those purchases stay with your account. Mods and resource packs you have installed locally on your computer are not affected by a name change.

Java Edition versus Bedrock Edition naming

Java Edition uses your Microsoft account profile name, which is what you change on account.microsoft.com. Bedrock Edition (the version on Windows 10, Windows 11, and consoles) uses a different system called a Gamertag, which you change in your Xbox settings, not your Microsoft account.

If you play both versions, changing your Microsoft profile name affects only Java Edition. Your Bedrock Gamertag stays the same unless you change it separately in Xbox settings. This can be confusing if you want to use the same name across both versions — you have to change each one individually.

Troubleshooting: name change is not showing up in-game

If you changed your Microsoft profile name but still see your old name in Java Minecraft, the launcher has not refreshed yet. Close the launcher completely (not just the window — make sure it is fully shut down), wait 10 seconds, then open it again and log in. This forces the launcher to fetch your current profile information from Microsoft.

If the old name persists after relaunching, sign out of the launcher entirely. Click your profile picture in the top right, select "Sign out", then sign back in with your email and password. This clears the cached profile data and pulls your current name fresh from Microsoft.

If you still see the old name after signing out and back in, check that you actually changed your name on account.microsoft.com and not somewhere else. Some players accidentally change their Xbox Gamertag instead, which does not affect Java Edition. Go back to account.microsoft.com, click "Your info", and verify that the name field shows what you expect.

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. If you changed your name and want to revert, you have to wait the full cooldown period. You can change back to any name you want, including an old one — there is no rule against reusing names you have had before.

What if someone else took the username I want?

Minecraft usernames are not reserved — the same name can belong to different accounts as long as they are not active at the same time. If another player is using the name you want, you cannot have it. You will have to pick a different name or wait to see if that player stops playing and Microsoft recycles the name.

Do I need to change my password when I change my username?

No. Your username and password are separate. Changing your profile name does not affect your password or your account security. You only need to change your password if you suspect someone else knows it or if you want to update it for other reasons.

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

Yes. Your UUID stays the same, so servers and friend lists recognize you by that hidden identifier, not by your visible name. Friends will see your new name, but they will not lose you from their friends list or have trouble joining servers you are on.

Can I change my username on mobile or console?

Java Edition runs only on Windows, Mac, and Linux, so there is no mobile version. If you play Minecraft on a phone or tablet, you are using Bedrock Edition, which has different naming rules. To change a Java username, you need to use a computer and go through account.microsoft.com.
