You need a Microsoft account to claim a username in Minecraft
To get a Minecraft username, you first create or sign into a Microsoft account, then launch the game and choose your name. The username you pick becomes your player identity — it's what other players see when you join servers and what appears on your character in the world. You can change it once every 30 days after you claim it, so your first choice doesn't have to be permanent.
The process is different depending on whether you own Minecraft Java Edition or Minecraft Bedrock Edition. Both require a Microsoft account, but the steps to set your username differ slightly between them.
Key Takeaways
- You must have a Microsoft account before you can claim a Minecraft username, whether you own Java or Bedrock Edition.
- In Java Edition, you set your username when you first launch the game after signing in with your Microsoft account.
- In Bedrock Edition, you set your username in the game settings under Profile, and it syncs across all devices where you play.
- You can change your username once every 30 days, but the name you choose must be between 3 and 16 characters and contain only letters, numbers, and underscores.
- If someone else has already claimed the username you want, you will need to choose a different one.
Setting up a Microsoft account first
Go to account.microsoft.com and click "Create one" if you don't already have an account. You'll need a valid email address and a password. Microsoft will send you a verification email — open it and confirm your account before you try to launch Minecraft.
If you already own Minecraft Java Edition under an older Mojang account, you can migrate that account to Microsoft. Sign into your Mojang account at minecraft.net, look for the migration option, and follow the prompts to link it to a Microsoft account. This keeps your username and any skins or capes you've earned.
Claiming your username in Java Edition
Launch the Minecraft Java Edition launcher and sign in with your Microsoft account credentials. The first time you log in, the game will prompt you to choose a username. Type the name you want — it must be 3 to 16 characters long and can only contain letters, numbers, and underscores. No spaces or special characters are allowed.
Once you submit your choice, the launcher checks whether that name is already taken. If it is, you'll see an error message and can try a different name. If it's available, the name is yours when ready and appears in the launcher. You can now launch the game and start playing.
Claiming your username in Bedrock Edition
Open Minecraft Bedrock Edition and sign in with your Microsoft account. Go to the main menu and select "Settings," then find "Profile" in the left sidebar. Look for the field labeled "Player Name" — this is where you enter your username.
Type your chosen name (3 to 16 characters, letters and numbers only) and confirm it. The name syncs across all devices where you play Bedrock Edition — your phone, tablet, console, or PC — so you'll see the same username everywhere. If the name is taken, you'll get a message telling you to try another one.
Rules for choosing a valid username
Your username must be between 3 and 16 characters. It can contain uppercase and lowercase letters (A–Z, a–z), numbers (0–9), and underscores (_). You cannot use spaces, hyphens, periods, or any other special characters. The game will reject your choice if it breaks these rules.
Minecraft also filters out usernames that contain profanity or impersonation of well-known people or brands. If you try to claim a name that violates this policy, the system will refuse it without explanation — you'll just see that it's unavailable. Try a different combination instead.
Changing your username after you claim it
You can change your username once every 30 days. In Java Edition, go to minecraft.net, sign in with your Microsoft account, and look for "Change Name" in your profile settings. In Bedrock Edition, go back to Settings > Profile > Player Name and type a new name the same way you did the first time.
The 30-day timer starts from the moment you change your name, not from when you claimed your original one. If you change your name and then want to change it again, you'll have to wait 30 days from that second change. Your old username becomes available for someone else to claim after you change it.
What to do if your desired username is taken
If the name you want already belongs to someone else, you cannot claim it. You have two options: pick a variation of that name (like adding numbers or underscores), or choose a completely different name.
Common variations include adding your birth year (like "Steve1995"), adding an underscore before or after the name (like "_Steve" or "Steve_"), or combining two words (like "SteveAlpha"). Since you can change your username every 30 days, you can also claim a temporary name now and switch to your preferred name later if it becomes available.
Frequently Asked Questions
Can I use the same username on Java and Bedrock Edition?
Yes, you can use the same username on both versions if you claim it on one and then set it on the other. However, they are separate accounts — your progress, skins, and items don't transfer between Java and Bedrock. You'll need to own both versions separately to play on both.
What happens to my username if I don't play for a long time?
Your username stays yours as long as your Microsoft account exists. Minecraft does not recycle inactive usernames. Even if you haven't played in years, your name remains claimed to your account.
Can I have spaces or special characters in my username?
No. Minecraft only allows letters (A–Z, a–z), numbers (0–9), and underscores (_). Spaces, hyphens, periods, and other symbols will be rejected when you try to claim the name.
Do I have to use my real name as my Minecraft username?
No. Your Minecraft username can be anything you want, as long as it follows the character rules and doesn't violate the profanity or impersonation policy. Many players use creative or fantasy names instead of their real names.
Can someone else claim my username if I change it?
Yes. Once you change your username, your old name becomes available for anyone else to claim. If you think you might want it back, wait to change it until you're sure you won't regret it.
