TikTok sets a one-hour time limit for teens under 18

TikTok will switch on a one-hour time limit for its users who are under 18 years old in a move to curb the amount of time teens spend on the service, the social video company announced Wednesday. 

The platform will introduce the new default setting in the coming weeks. 

Minors will have the power to switch off the setting, however. When users who are 18 or younger reach the one-hour time limit, they will be prompted to enter a passcode to activate additional scrolling time — a disruption that TikTok said could prompt teens to be more intentional about the time they spend on the app.
