Where to find the username setting on Lemon8

Open Lemon8 and tap the profile icon in the bottom right corner. From your profile page, tap the three horizontal lines (menu icon) in the top right. Select "Settings and privacy," then tap "Account." The "Username" field appears near the top of that screen — that is where you make the change.

Lemon8 is ByteDance's short-form video app, similar to TikTok in layout. The settings path is consistent whether you use iOS or Android, though the exact icon positions may shift slightly between app updates.

Key Takeaways

  • Your username change takes effect when ready, but other users may see the old name in their follows or messages for a few hours while the system syncs.
  • You can change your username once every 30 days, so choose carefully before you submit.
  • Your new username must be between 3 and 20 characters, use only letters, numbers, underscores, and periods, and cannot be blank or spaces only.
  • Changing your username does not affect your account security, password, or the content you have already posted.

What usernames Lemon8 will and will not accept

Lemon8 rejects usernames that are already taken by another account. If you see an error message saying the name is unavailable, someone else owns it — you cannot reserve it or request it back. Try a variation: add a number, use an underscore, or pick a different name altogether.

The app also blocks usernames that violate its community guidelines — names that include slurs, impersonate real people or brands, or are designed to deceive. If your chosen name is rejected for this reason, the app will say "Username not allowed" rather than "unavailable." Pick a different name and try again.

Usernames are case-insensitive on Lemon8, meaning "JohnSmith" and "johnsmith" are treated as the same account. The system will accept either capitalization, but it stores whichever version you typed first.

The 30-day waiting period between changes

Once you change your username, you cannot change it again for 30 days. This limit exists to prevent spam accounts from cycling through names to evade detection or to stop users from constantly switching names in ways that confuse their followers.

If you change your username and when ready realize you made a typo or hate the new one, you are locked in for a month. The only workaround is to wait the full 30 days. Lemon8 support cannot override this timer, so plan your change carefully and double-check the spelling before you confirm.

What happens to your old username after you change it

Your old username becomes available for someone else to claim when ready after you change it. If you had a popular or memorable username, another user could take it within minutes. There is no grace period or hold — the moment you submit the new name, the old one enters the pool of available usernames.

If you think you might want to reclaim your old username later, you cannot do so unless the person who took it gives it up. Plan accordingly if your old username is valuable to you or your brand.

How the change appears to other users

Your new username shows on your profile when ready after you confirm the change. However, other users may see your old username in their notifications, direct messages, or follows list for a few hours while Lemon8's servers sync the change across all devices and regions. This delay is normal and does not mean anything went wrong.

Your old posts, likes, and comments are not affected. They remain attached to your account under your new username. Anyone who visits your profile or searches for your new username will see your full history.

Troubleshooting a failed username change

If you tap "Confirm" and see an error, the most common cause is that the username was taken between the time you typed it and the time you submitted. Try a different variation and submit again when ready.

If the error says "Something went wrong" or "Try again later," your internet connection may have dropped or Lemon8's servers may be temporarily overloaded. Wait a few minutes, make sure you have a stable connection, and try the same username again. If it fails a second time, try a different username — the first one may have been claimed in the meantime.

If you are locked out of your account or cannot reach the Settings menu, the problem is not the username feature itself. Restart the app, log out and back in, or reinstall Lemon8 if the issue persists.

Frequently Asked Questions

Can I change my username back to the old one after 30 days?

Only if no one else has claimed it. If another user took your old username, you cannot get it back unless they change theirs first. You would have to wait for them to voluntarily give it up or for their account to be deleted.

Does changing my username affect my followers or my follower count?

No. Your followers remain your followers, and your follower count stays the same. They will see your new username the next time they visit your profile or see your content in their feed.

What if I see my username is taken but I never created that account?

Someone else created an account with that username. You cannot claim it or request Lemon8 to remove it unless the account violates the community guidelines. If the account is impersonating you or using your real name without consent, report it through the app's reporting feature.

Can I use special characters or emojis in my username?

No. Lemon8 only accepts letters (A–Z, a–z), numbers (0–9), underscores (_), and periods (.). Emojis, spaces, hyphens, and other symbols are not allowed.
