Yes, you can change your Kahoot username, but the process and restrictions depend on which type of account you have

Kahoot lets you change your username after you create an account, though the exact steps differ between free accounts and paid plans. If you have a free account, you can change your username once every 30 days through your account settings. Paid accounts (Kahoot+ or school/business plans) may have different rules depending on your subscription level. The change takes effect when ready across all your quizzes and public profile.

The username you choose must be between 3 and 25 characters, contain only letters, numbers, and underscores, and cannot be blank. Kahoot does not allow spaces in usernames. If you try to change to a name that is already taken or violates their content policy, the system will reject it and ask you to pick something else.

Key Takeaways

  • Free Kahoot accounts can change their username once every 30 days through account settings on the website or app.
  • Your new username must be 3 to 25 characters long and can only contain letters, numbers, and underscores.
  • The username change applies to your profile and all your quizzes when ready, but other players will see the new name only after they refresh their screen.
  • If you hit the 30-day limit on a free account, you must wait until the timer resets before changing again.
  • Paid Kahoot accounts may have different username change policies depending on whether you are on a school, business, or individual subscription.

How to change your username on desktop

Log into your Kahoot account on the website and click your profile icon in the top right corner. Select "Account settings" from the dropdown menu. On the Account settings page, find the "Username" field and click the edit button next to it. Type your new username and click "Save" or "Confirm".

If you see a message saying you cannot change your username yet, you have hit the 30-day limit on a free account. The system will tell you when you can change it again. If the name you entered is already taken or contains forbidden characters, Kahoot will show an error message and ask you to try a different name.

How to change your username on the mobile app

Open the Kahoot app on your phone or tablet and tap the profile icon at the bottom of the screen. Tap "Account settings" or "Settings" depending on your device. Look for the username field and tap the edit or pencil icon next to it. Enter your new username and tap "Save" or "Confirm".

The mobile app follows the same 30-day rule as the website. If you changed your username recently on desktop, that timer applies to the app as well — the two are linked to the same account. You will see the same error messages if the name is taken or invalid.

What happens when you change your username

Your new username appears on your public profile when ready. Any quizzes you created will show the new name as the author. If other players have bookmarked your quizzes or followed your profile, they will see your updated name the next time they refresh their screen or reopen the app.

Changing your username does not affect your quiz history, points, or achievements. Your account data stays the same — only the display name changes. If you were in the middle of hosting a live game when you changed your username, players in that game may still see your old name until the game ends and they refresh.

The 30-day waiting period on free accounts

Kahoot enforces a 30-day cooldown between username changes for free accounts to prevent spam and account abuse. The timer starts from the moment you confirm your last username change, not from when you attempt a new one. If you change your username on day 1, you cannot change it again until day 31.

This limit applies only to free accounts. If you upgrade to Kahoot+ or a school or business plan, check your subscription details to see if the restriction changes. Some paid plans may allow more frequent changes or remove the limit entirely, though Kahoot does not publicly list these differences.

Usernames you cannot use

Kahoot blocks usernames that contain hate speech, slurs, or sexually explicit content. The system also rejects names that impersonate Kahoot staff or famous public figures. Usernames that are blank, contain only spaces, or use special characters other than underscores will not be accepted.

If you try to use a name that violates these rules, Kahoot will show an error message but will not explain which rule you broke. Try a different name that is clearly distinct from the one you attempted. If you believe your rejected username should have been allowed, you can contact Kahoot support through their website.

What to do if you cannot change your username

If you see a message that says you cannot change your username, the most common reason is the 30-day waiting period. Check the message to see when you will be able to change it again. If the message says the name is already taken, try adding a number or underscore to make it unique.

If you are on a paid plan and still cannot change your username, your subscription type may have different rules. Log into your account settings and look for any notices about username restrictions. If you see no clear explanation, contact Kahoot support with your account email and a screenshot of the error message.

Frequently Asked Questions

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

Yes, as long as no one else has claimed that old username and you have waited 30 days since your last change. If someone else took it, you will need to pick a different name. The system treats it as a new username, not a restoration of your old one.

Does changing my username affect my quiz scores or leaderboard position?

No. Your account data, quiz history, and leaderboard rank all stay the same. Only the name displayed next to your scores changes. Other players will see your new name on leaderboards after they refresh their screen.

What if I forgot my username?

Log into your account using your email address and password. Once you are logged in, go to Account settings to see your current username. If you cannot remember your password, use the "Forgot password" link on the login page to reset it.

Can I use spaces or special characters in my username?

No. Kahoot only allows letters, numbers, and underscores. Spaces and other special characters like hyphens, periods, or @ symbols will cause the system to reject your entry. Use underscores instead if you want to separate words.

How long does it take for my new username to show up everywhere?

Your new username appears on your profile and quizzes when ready. Other players will see it the next time they refresh their screen or reopen the app. If you are hosting a live game, players in that game may see your old name until the game ends.
