Remember that the typical TikTok user is young. Many of the users of the regular TikTok app are kids or just a bit older. By default, TikTok is set to 'Public", but by changing that setting to "Private," you can protect your kids if you're concerned. With a private account, only people you approve can follow, comment on, and like your videos. If you still prefer your child's account to remain public, you can turn off "Allow others to find me."
