Where to change your Ninja Kiwi username

You change your Ninja Kiwi username through your account settings on the Ninja Kiwi website, not within the games themselves. Log in to your account at ninjakiwi.com, go to Account Settings, and look for the Profile or Username section. The exact location depends on whether you're using an older account created before Ninja Kiwi unified its login system or a newer one, but both routes start from the same login page.

If you play games like Bloons TD 6, Bloons TD Battles, or Battles 2, your username is tied to your Ninja Kiwi account across all of them. Changing it in one place changes it everywhere you play on that account. This means you don't have to update your name separately in each game.

Key Takeaways

  • Log in at ninjakiwi.com and navigate to Account Settings to find the username change option.
  • Your username change applies to all Ninja Kiwi games linked to that account at once.
  • Some usernames may be unavailable if another player is already using them.
  • After you change your username, it may take a few minutes to update across all your games.

Step-by-step process for changing your username

Start by opening ninjakiwi.com in your browser and clicking the login button, usually in the top right corner. Enter your email address and password. Once you're logged in, look for Account Settings — this is often found by clicking your profile icon or username in the top navigation, then selecting Settings or Account.

In Account Settings, find the section labeled Profile, Username, or Display Name. Click the edit or change button next to your current username. Type in the new username you want. Ninja Kiwi will tell you when ready if that name is already taken by another player. If it is, you'll need to choose something different. Once you've entered a name that's available, save the change. The system will confirm the update, and your new username should appear across your account within a few minutes.

What happens to your old username

Once you change your username, your old one becomes available for other players to use. If you change your mind within a short window, you might be able to change it back, but there's no may provide — if someone else claims your old name in the meantime, you won't be able to reclaim it. For this reason, make sure you're ready to commit to your new username before you save the change.

Your account history, progress in games, and any purchases or cosmetics you own stay with your account regardless of what username you choose. The username is just the display name other players see; it doesn't affect your game data or account security.

Username rules and restrictions

Ninja Kiwi usernames typically have length limits — usually between 3 and 20 characters — and may not allow certain special characters or spaces. The system will show you an error message if your chosen name breaks these rules. Usernames are usually case-insensitive, meaning "Player123" and "player123" are treated as the same name.

Avoid usernames that contain slurs, hate speech, or sexually explicit content. Ninja Kiwi moderators can force a username change if your name violates their community guidelines, and repeated violations can result in account restrictions. If you're unsure whether a name might cause problems, err on the side of something neutral and friendly.

Troubleshooting if the change doesn't work

If you've saved a new username but it's not showing up in your games after 10 minutes, try logging out completely and logging back in. Clear your browser cache if you're playing through a web version of a Ninja Kiwi game, or restart the app if you're on mobile. Sometimes the change needs a fresh session to sync across all devices.

If you're still seeing your old username after that, check whether you're logged into the same account in your game as you are on the website. Some players have multiple accounts by accident — one for the website and one for the game app. Make sure you're changing the username on the account you actually play with. If you're still stuck, the Ninja Kiwi support team can help; you can reach them through the Contact or Support link on their website.

Changing your username on mobile versus desktop

The process is the same whether you're on a phone, tablet, or computer: you change your username on the Ninja Kiwi website, and the change syncs to your games. You don't change it within the game app itself. If you're on mobile and find it hard to navigate the website, you can open ninjakiwi.com in your phone's browser and follow the same steps as you would on a desktop.

After you change your username on the website, close and reopen your game app to see the new name. The app may cache your old username for a while, so a fresh start usually forces it to pull the updated information from Ninja Kiwi's servers.

Frequently Asked Questions

Can I change my username back to what it was before?

You can change it back if no one else has claimed that name in the meantime. Since old usernames become available when ready after you change them, someone else might take it. If that happens, you won't be able to use it again unless that player changes their name later.

How often can I change my username?

Ninja Kiwi doesn't publicly state a limit on how often you can change your username. However, if you change it very frequently or appear to be cycling through names to evade moderation, your account may be flagged. Treat your username as something you'll keep for a while.

Will changing my username affect my rank or progress in games?

No. Your rank, wins, losses, cosmetics, and all game progress stay exactly the same. Only the name that displays to other players changes. Your account ID and all your data remain linked to you.

What if the username I want is taken?

You'll need to choose a different name. Try adding numbers, underscores, or slight variations to your preferred name. The system will let you know when ready if a name is available when you try to save it.

Do I need to change my password when I change my username?

No. Your username and password are separate. Changing your username doesn't affect your login credentials or account security. You only need to change your password if you suspect someone else knows it.
