As the most popular app in the world for young children and adolescents, TikTok relies on quick, constant video streams designed to maximize attention. It not only plays havoc with a child’s viewing time, but also their exposure to inappropriate content. Family controls raise your awareness and allow you to set limitations. Go to Profile > Settings > Family Pairing, then scan a QR code. You’ll choose and link to the child’s account, tweaking rules for restricted content, screen time and privacy measures.
