TikTok announced that every account held by an under-18 user will have a default 60-minute daily screen time limit. Minors will be prompted to enter a passcode and make an “active decision” to keep watching. Users under 13 will need a parent or guardian to enter a passcode for an extra 30 minutes of viewing time. Families in the U.S. have struggled with limiting the amount of time their children spend on the app.
 　The changes arrived when different governments were concerned about the Chinese-owned app’s security and data privacy. The U.S. federal agencies were given 30 days to wipe TikTok off all government devices, followed by the Canadian government and the European Union’s executive branch to do the same. The Danish parliament also urged lawmakers and employees against having TikTok on work phones.

　TikTok 宣布，針對十八歲以下用戶，將設定每日六十分鐘的螢幕時間限制，會提醒未成年者輸入密碼，「主動決定」是否繼續觀看。十三歲以下用戶則須由父母或監護人輸入密碼，才能獲得額外三十分鐘的觀看時間。美國家庭一直以來難以限制孩子使用這款應用程式的時間。
　這項改變正逢各國政府擔心，這款中國應用程式帶來的安全與個資隱憂。美國聯邦機關就被下令得在三十天內，移除所有公家裝置上的TikTok，加拿大和歐盟行政機關也跟進。丹麥國會則呼籲議員們及員工，不要在公務手機安裝TikTok。
