Popular video sharing platform TikTok has announced a new 60-minute daily screen time limit for users under 18.

All accounts belonging to users under 18 years old will automatically be set to a 60-minute daily screen limit,“to help teens manage their time on TikTok,” the company said.

Once young users reach the new limit, they will be promoted to enter a passcode to continue using the service that day.

The move comes as concerns continue to grow about social media’s impact on the mental health of children.

Cormac Keenan, head of trust and safety at TikTok, said the company had worked with researchers in developing the new limits.

“While there’s no collectively endorsed position on the ‘right’ amount of screen time, or even the impact of screen time more broadly, we consulted the current academic research and experts from the Digital Wellness Lab at Boston Children’s Hospital in choosing this limit.”
