Where to change your username

You change your Minecraft Java username through your Microsoft account settings, not through the game launcher itself. This is because Microsoft owns Minecraft and links your game to your Microsoft account rather than storing a separate username in the launcher.

The actual change happens on the Microsoft account website at account.microsoft.com. You log in there, find the profile section, and update the name associated with your account. The change takes effect when ready in Minecraft Java Edition, though you may need to restart the launcher to see it reflected in-game.

Key Takeaways

  • You change your username through your Microsoft account settings at account.microsoft.com, not through the Minecraft launcher.
  • The change takes effect right away, but you should restart the Minecraft launcher to see the new name in-game.
  • You can only change your username once every 30 days, so choose carefully before you confirm.
  • Your old username becomes available for other players to claim after you change it.

Step-by-step process to update your name

Start by opening a web browser and going to account.microsoft.com. Sign in with the Microsoft account that owns your Minecraft Java Edition license. Once you are logged in, look for the "Your info" or "Profile" section in the left sidebar — the exact wording varies depending on your account type.

Click on "Manage your Microsoft account" or the profile option. You should see a section labeled "Gamertag" or "Display name" — this is what appears in Minecraft. Click the edit button next to it. Type your new username into the field. Microsoft will check whether the name is already taken; if it is, you will see a message and need to choose something different.

Once you find an available name, click "Save" or "Confirm". The system will remind you that you can only change your username once every 30 days. If you are certain about the change, confirm it. Close the browser and open the Minecraft launcher. You may need to restart the launcher completely for the new name to appear in your profile.

What happens to your old username

When you change your username, the old one does not stay reserved for you. Other players can claim it when ready, so if you change your mind later, you may not be able to get it back. This is why it is worth taking a moment to decide on a new name before you confirm the change.

Your UUID — the unique identifier Minecraft uses behind the scenes — stays the same. This means your worlds, skins, and server permissions are tied to your UUID, not your username. If someone else takes your old name, they will not have access to your worlds or progress.

The 30-day waiting period between changes

Microsoft enforces a 30-day cooldown between username changes. This means once you change your name, you cannot change it again for 30 days. The timer starts the moment you confirm the change, not when you first visit the settings page.

If you make a mistake and realize you do not like your new username, you have to wait the full 30 days before you can change it again. This is why testing the name in your head or asking friends what they think before you confirm is a good idea.

Troubleshooting: name not showing up in-game

If you changed your username on the Microsoft website but the old name still appears in Minecraft, the launcher has not refreshed yet. Close the Minecraft launcher completely — not just the game window, but the entire launcher process. Wait a few seconds, then open it again and log in.

If the name still has not changed after restarting, try signing out of the launcher entirely. Go to the launcher settings, find the account section, and click "Sign out". Then sign back in with your Microsoft account. This forces the launcher to fetch your current profile information from Microsoft's servers.

Changing your skin and other profile details

Your username is separate from your skin, the visual appearance of your character in-game. You can change your skin through the Minecraft launcher without waiting 30 days. Open the launcher, click on your profile picture in the top right, and select "Skins". You can upload a custom skin file or choose from the default options.

You can also change your skin on the Minecraft website at minecraft.net by logging in and going to your profile. The skin change takes effect when ready, though you may need to restart the launcher to see it in-game.

Frequently Asked Questions

Can I change my username more than once every 30 days?

No. Microsoft enforces a strict 30-day cooldown between changes. Once you confirm a new username, you cannot change it again until 30 days have passed from that confirmation date.

What if my desired username is already taken?

The Microsoft account website will tell you when ready if a name is taken when you try to save it. You will need to choose a different name. You can try variations like adding numbers, underscores, or abbreviations until you find one that is available.

Will changing my username affect my worlds or server progress?

No. Your worlds and server permissions are tied to your UUID, which never changes. Your new username will have access to everything your old username had. Other players on servers may need to re-add you to their friends list if they use the old name, but your actual progress is unaffected.

Do I need to change my username in the launcher settings too?

No. The launcher pulls your username directly from your Microsoft account. Changing it on the Microsoft website is the only step you need. The launcher will show your new name once you restart it.

Can I get my old username back if someone else takes it?

Only if that person changes their username and releases it. Since usernames become available when ready after you change yours, someone else can claim it right away. You cannot reserve an old username or ask Microsoft to hold it for you.
