Minecraft: Java Edition Username FAQ

What are the requirements for creating a username? 

  • Must have 3-16 characters 
  • No Spaces are allowed between characters 

Accepted characters: 

  • A-Z (upper and lower case) 
  • 0-9 
  • The only special character accepted is _ (underscore) 

Note: You can no longer create usernames with less than three characters. 


Where can I find my username? 

If you have a Mojang account, you can find and edit your username on your Mojang account page. 

Can I change my username? 

Users who have a Mojang account or a Microsoft account can change their username for free at www.minecraft.net/en-us/profile. Click Change next to your profile name. 

If you have an older account and you sign in with your username, you need to migrate to a Mojang account before you can change your username. 

How often can I change my username? 

Every 30 days. 

When you change your username, your previous name is saved for 37 days. This gives you an additional week to change back if you change your mind before your previous username becomes available to anyone else. 

Is the username you want unavailable? 

If the username you want is unavailable, you must choose another. Minecraft Support cannot help you change to a username that is unavailable.   
If I change my username, can other players see my previous usernames? 

Yes. username changes are set up so that you can get a username that you prefer and are not designed to circumvent bans or mislead. Previous usernames are saved and visible to other players. 

If my old username had my name in it, can I have this name removed from my username history? 

Yes. If your current or past usernames have any personally identifiable information in them, you can contact Minecraft Support and have it removed from your history.  

Note: This request is strictly limited to personally identifiable information. 
After I changed my username, I got the error message “not authenticated with Minecraft.net” when I changed my usernamewhat should I do? 

You must log out completely and then log back in. This refreshes your profile's authentication and connection with our servers. 

Log out and log back in 

  1. In the Minecraft game launcher, click your username or email address in the top right corner. 
  2. Click Log out. 
  3. Log back in with your account credentials. 

If I ban someone on my server, and they change their username, do they remain banned? 

Yes, and the same is true when someone is whitelisted, or has Operator level permissions. Account-level features on an unmodified or “Vanilla” server stay the same because the system is using your profile's unique ID instead of the username.  

NoteThis does not include the scoreboard system, which uses usernames, and is not meant to store long-term player data. 

Will Minecraft Support help me change my username? 

No, the system is set up so that users can change their usernames. You can change your username every 30 days if you wantMinecraft Support also cannot assist with a username that is unavailable nor a username with less than three characters. 

Is there username moderation? Can I report someone? 

Mojang Studios has always had a pretty relaxed stance on usernames. Someone who chooses an inappropriate username is often banned by the servers that they join. Even though username changes are now a feature, people have been able to register questionably appropriate usernames since 2009, and the community has self-regulated.  

Do not report other player usernames to Mojang Studiosif you encounter an inappropriate name while playing on a server, please report it to the server owner. With that in mind however, Mojang Studios reserves the right to change offensive names.
