The screentime limit will be rolled out in the 'coming weeks'

TikTok has announced it will automatically set a screentime limit on the accounts of all users under the age of 18, as part of a string of new safeguarding features for younger users. The video-sharing app revealed on Wednesday that "every account belonging to a user below age 18 will automatically be set to a 60-minute daily screen time limit." Once users reach the hour-long limit, they will be prompted to input a passcode in order to continue using the app, requiring them to "make an active decision to extend that time." Users are able to opt out of the screentime limit but will be prompted to set a daily limit if they spend more than 100 minutes a day on the app, TikTok said. The new feature will be rolled out "in the coming weeks." TikTok's Head of Trust and Safety, Cormac Keenan, said that whilst there is no "collectively-endorsed position on the 'right' amount of screen time", the company had consulted the Digital Wellness Lab at Boston Children's Hospital in choosing this limit.

Along with the screentime limit feature, TikTok also announced ways caregivers can customize daily time limits, sleep reminders, and when notifications can be muted. The policies come amid growing scrutiny over the app's - and other social media platforms' - impact on children and teenagers. The likes of TikTok, Facebook, and Instagram are being urged to do more to safeguard children using their apps.
