Want a fresh identity on TikTok? Open the app, visit your profile, and tap “Edit profile.” Select “Username,” then craft a new, standout name—TikTok will confirm if it’s available. Save it once approved. You’re limited to one change every 30 days, so choose wisely. Your new username must be 2–24 characters, using only letters, numbers, periods, or underscores. Changing it also updates your profile link, so share your new handle to keep your audience in the loop.
