Where to find your username if you still have access to the launcher
The fastest way to find your Minecraft Java username is to open the Minecraft Launcher on the computer where you play. When you launch the game, your username appears in the bottom left corner of the launcher window before you click "Play". Write down exactly what you see there — that is your Java username, and it is what other players see when you join a server or realm.
If you are already in a game, pause and look at the top left of your screen. Your username displays there in white text. This is the name that appears above your character's head to other players and the name used in chat messages. Take a screenshot or write it down so you have it saved.
Key Takeaways
- Your Minecraft Java username appears in the bottom left of the launcher window and in the top left corner during gameplay.
- If you own the account through Mojang or Microsoft, you can sign into your account page to see your username listed under profile settings.
- The username you use to log in (your email) is different from your in-game username — check your profile page to see which is which.
- If you cannot remember your password, use the "Forgot Password" option on the Minecraft login page to reset it and regain access.
Check your Minecraft account page online
Go to minecraft.net and sign in with the email address and password you use for Minecraft. Once you are logged in, click on your profile icon in the top right corner and select "Profile" from the menu. Your in-game username will be listed on this page under "Username" or "Minecraft Username".
If you own a newer account created after 2020, you signed in with a Microsoft account instead. Go to account.microsoft.com, sign in, and look for "Minecraft Profile" in the left menu. Your Java username appears there. This page also shows you when the account was created and what email address is tied to it.
Understand the difference between login email and username
Many people confuse their login email with their in-game username. Your login email is what you type into the launcher to sign in — it is usually an email address. Your in-game username is the name that displays above your character's head and in chat. These are two separate things, and you need the in-game username to join servers or play with friends.
If you created your account years ago, you may have set a username before Minecraft switched to email logins. Check your profile page to see both your email and your username listed separately. The username is what you are looking for.
What to do if you cannot access your account
If you do not remember your password, go to minecraft.net and click "Sign In" in the top right. On the login page, click "Forgot your password?" and enter the email address tied to your account. Minecraft will send you a password reset link. Check your email (including spam folders) and click the link to create a new password.
Once you reset your password and sign back in, you will see your username on your profile page. If you do not remember which email address you used, try the email addresses you commonly used years ago when you created the account. If none of them work, contact Minecraft Support through the help page at minecraft.net/en-us/article/contact-minecraft-support.
Find your username in game files if the launcher will not open
If your launcher is broken or will not start, you can find your username by looking at your game files. On Windows, open File Explorer and navigate to C:\Users\[YourComputerName]\AppData\Roaming\.minecraft. On Mac, open Finder, press Command+Shift+G, and paste ~/Library/process Support/minecraft. On Linux, open your file manager and go to ~/.minecraft.
Look for a file called launcher_profiles.json and open it with Notepad or any text editor. Search the file for the word "lastVersionId" or look for a section labeled "profiles". Your username should appear near these sections. It will look like a string of text without spaces. If you see multiple usernames, the one listed under your most recent profile is the one you use most often.
Check with friends or on servers you have played
If you have played on a multiplayer server or realm with friends, ask them what your username is. They will see it in the player list or in chat messages. You can also join a server you have played on before — your username will appear in the player list as soon as you connect, and you can see it there.
If you have a Discord server where you play with others, check the member list or search for your messages. Your Minecraft username might be listed in your Discord profile or mentioned in chat history.
Frequently Asked Questions
Is my username the same as my Microsoft account email?
No. Your Microsoft email is what you use to log into the launcher. Your Minecraft username is your in-game name that other players see. Check your profile page at minecraft.net to see both listed separately.
Can I change my username after I find it?
Yes. On your profile page at minecraft.net, you can change your username once every 30 days. Click on your username and select "Change" to pick a new one. The change takes effect when ready in-game.
What if I see multiple usernames in my launcher?
If you have multiple accounts on the same computer, each one has its own username. The launcher shows all of them in the account selector. Click on each one to see which username belongs to which account, or check your profile page while signed into each account.
Why does my username look different in the launcher than in-game?
The launcher sometimes displays usernames with different capitalization or formatting than what appears in-game. The version in-game is the correct one — that is what other players see. Your profile page shows the official version.
Can I recover a username from an old account I no longer use?
If you remember the email address tied to the old account, you can sign in at minecraft.net and see the username on your profile page. If you cannot remember the email or password, contact Minecraft Support with proof of ownership (like a purchase receipt) and they may be able to help you recover it.
