How To Change TikTok Username phone
To change your TikTok username, open the app and go to your profile. Tap “Edit profile,” then tap “Username.” Enter your desired new username—TikTok will check if it’s available. If it is, tap “Save.” You can only change your username once every 30 days. Usernames must be 2–24 characters and can include letters, numbers, underscores, and periods. Keep in mind that changing it also updates your TikTok profile URL, which may affect existing links to your account.
