You can change your Kahoot username from your account settings on any device

Open Kahoot on your phone, tablet, or computer and sign into your account. Go to your profile or account settings — usually a gear icon or your name in the top right corner. Look for a "Username" or "Profile" option, select it, type your new username, and save the change. The new name takes effect when ready and shows up the next time you play or create a quiz.

The exact location of this setting varies slightly depending on whether you're using the mobile app or the web version, but the process is the same on both. You don't need to log out and back in — just refresh the page or close and reopen the app to see your new username everywhere.

Key Takeaways

  • Your username change happens when ready and appears across all your Kahoot activity once you refresh or reopen the app.
  • You can change your username as many times as you want — there's no limit on how often you update it.
  • Your old username is released when ready, so someone else can claim it if they want to.
  • Changing your username does not affect your quiz history, points, or any quizzes you've already created.

Changing your username on the Kahoot mobile app

Tap the profile icon in the top right corner of the home screen. This usually looks like a circle with your initials or a generic person silhouette. From there, select "Profile" or "Account Settings."

Find the "Username" field and tap it to edit. Delete your current username and type the new one you want. Tap "Save" or "Done" to confirm. Close the settings and return to the home screen — your new username should appear when ready in your profile.

Changing your username on Kahoot's website

Sign in at kahoot.com and click your profile picture or name in the top right corner. Select "Profile" or "Settings" from the dropdown menu that appears.

Locate the "Username" field on your profile page. Click the edit button next to it (usually a pencil icon), type your new username, and click "Save." The change takes effect right away. If you don't see the change reflected when ready, refresh the page in your browser.

Rules for choosing a new Kahoot username

Kahoot usernames can contain letters, numbers, and some special characters like underscores or hyphens. Most usernames are between 3 and 20 characters long, though the exact limits may vary. Avoid spaces — Kahoot typically doesn't allow them in usernames.

You cannot use a username that's already taken by another active Kahoot account. If you try to save a username that someone else has, Kahoot will tell you it's unavailable and ask you to pick a different one. Usernames are not case-sensitive, so "JohnSmith" and "johnsmith" are treated as the same username.

What happens to your old username and account data

Your quiz history, points, badges, and all quizzes you've created stay attached to your account. Changing your username doesn't reset anything — it's purely a display change. Anyone who had you added as a friend or followed your quizzes will still see your updated name the next time they check.

Your old username becomes available for someone else to use as soon as you change it. If you want to keep that username reserved, don't change it. There's no way to "hold" an old username or reclaim it later if someone else takes it.

Troubleshooting username change problems

If the save button is grayed out or won't respond, make sure you've actually typed something different in the username field. Kahoot won't let you save if the new name is identical to your current one. Also check that your new username doesn't contain spaces or characters Kahoot doesn't allow.

If you see an error message saying the username is unavailable, someone else has already claimed it. Try adding a number, underscore, or different spelling. If your changes aren't showing up after you save, close the app completely and reopen it, or refresh your browser if you're on the web version. Log out and back in if the change still doesn't appear.

Frequently Asked Questions

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

Only if no one else has claimed it. Once you change your username, the old one is released to the public. If someone has taken it, you'll need to pick a different name. You can always try reclaiming it later if the other person stops using their account.

Does changing my username affect my friends or followers?

No. Your friends and followers stay connected to your account. They'll see your new username the next time they open Kahoot, but the connection itself doesn't break. You don't need to re-add anyone or send new friend requests.

How often can I change my username?

Kahoot doesn't limit how many times you can change your username. You can update it as often as you want, though changing it very frequently might confuse people trying to find your quizzes or remember your name.

What if I forgot my password and can't sign in to change my username?

Use the "Forgot Password" link on the Kahoot login page to reset it. Enter the email address connected to your account, and Kahoot will send you a password reset link. Once you've set a new password, sign back in and change your username from your profile settings.

Can I use special characters or emojis in my username?

Kahoot allows some special characters like underscores and hyphens, but not all. Emojis typically don't work in usernames. Stick to letters, numbers, underscores, and hyphens to avoid errors. If a character doesn't work, Kahoot will let you know when you try to save.
