Change your username through the Minecraft Launcher
To change your Java Edition username, open the Minecraft Launcher and look at the top left corner where your current username appears. Click on it, and a dropdown menu will show your account options. Select "Change" or the pencil icon next to your name — the exact button depends on which version of the launcher you have, but both lead to the same place.
A text field will open where you can type your new username. Minecraft usernames can be 3 to 16 characters long and can include letters, numbers, and underscores. Once you type the name you want, click "Done" or "Save". The launcher will confirm the change when ready, and your new username will appear the next time you start the game.
You do not need to restart your computer or reinstall anything. The change takes effect as soon as you close the dialog box and is ready to use the next time you launch the game.
Key Takeaways
- Click your username in the top left of the Minecraft Launcher and select the change or edit option to open the username field.
- Your new username must be between 3 and 16 characters and can include letters, numbers, and underscores only.
- The change saves when ready when you click Done and takes effect the next time you launch the game.
- Changing your Java Edition username does not affect your Microsoft account, password, or any other game settings.
- You can change your username as often as you want, though some servers may have cooldown periods between changes.
What happens to your old username
Once you change your username, the old one becomes available for someone else to claim after a short period. If you want to keep that name reserved, you should change it back before logging out. However, if you straightforward want a fresh start, the old username will eventually cycle back into the pool of available names.
Any skins, capes, or cosmetics you owned stay with your account and will display under your new username. Your game progress, achievements, and inventory in single-player worlds are tied to your account, not your username, so nothing is lost when you make the change.
Troubleshooting if the change does not appear
If you changed your username but it still shows the old name in the launcher, close the launcher completely and reopen it. Sometimes the display does not refresh when ready, but closing and reopening forces the launcher to reload your account information.
If the old username still appears after reopening the launcher, check that you are logged into the correct Microsoft account. If you have multiple accounts on your computer, the launcher might be showing a different account than the one you edited. Click the account dropdown at the top left and make sure you are on the account you just changed.
Changing your username on servers and multiplayer
When you join a multiplayer server or realm, other players will see your new username when ready. However, some servers keep records of old usernames for moderation or ban purposes, so staff may still know who you are even if you change your name.
If you are banned from a server, changing your username will not lift the ban. Most servers ban by account ID, not by username, so you cannot bypass a ban by renaming. The same applies to whitelisted servers — your account is whitelisted, not your username, so the change does not affect your access.
Username rules and restrictions
Minecraft usernames follow specific rules. You can use uppercase and lowercase letters (A–Z, a–z), numbers (0–9), and underscores (_). You cannot use spaces, special characters like hyphens or periods, or emoji. The name must be at least 3 characters and no more than 16 characters long.
If you try to use a name that is already taken, the launcher will tell you when ready and will not let you save the change. Try a different variation — adding a number, an underscore, or a different spelling often solves this. If the name you want is taken, you can check back later, as inactive accounts sometimes release their usernames, but there is no way to know when that will happen.
Difference between username and Microsoft account email
Your Minecraft username is what other players see in the game. Your Microsoft account email is what you use to log into the launcher and is separate from your username. Changing your username does not change your email, and changing your email does not change your username.
If you want to change the email address tied to your Microsoft account, that is a different process done through the Microsoft account website, not the Minecraft Launcher. Your username change happens only in the launcher and affects only how your name appears in the game.
Frequently Asked Questions
How often can I change my username?
You can change your Java Edition username as often as you want through the launcher. However, some multiplayer servers enforce their own cooldown periods — you might not be able to change your name again on that server for 30 days. This is a server rule, not a Minecraft rule, and varies by server.
Will changing my username delete my worlds or progress?
No. Your single-player worlds, achievements, and inventory are tied to your account, not your username. Everything stays exactly as it was. The only thing that changes is what other players see when you join multiplayer games.
Can I change my username back to what it was before?
Yes, if no one else has claimed that name. straightforward open the launcher, click your username, and type the old name back in. If someone else has taken it, you will see a message saying the name is unavailable, and you will need to choose a different one.
Does changing my Java username affect my Bedrock Edition account?
No. Java Edition and Bedrock Edition are separate games with separate usernames. Changing your name in Java Edition does not change anything in Bedrock Edition, and vice versa. You manage each username independently through its own launcher.
What if the launcher will not let me save my new username?
The most common reason is that the name is already taken. Try adding a number or underscore to make it unique. If you see an error message instead, try closing the launcher completely and reopening it, then try again. If the problem continues, check that you are logged into the correct Microsoft account.
