TikTok's default 60-minute prompt for under-18s

TikTok announced a default 60-minute daily limit for under-18s that a passcode can override. A state complaint, as reported, alleges its own test cut use by about 1.5 minutes a day. TikTok disputes the complaint. No independent evaluation was opened.

1 March 2023. Date of TikTok's announcement. The allegations about how little the prompt reduced use come from a state complaint reported in October 2024. Chronology section: 2010 to 2026.

What happened

On 1 March 2023 TikTok announced that every account belonging to a user under 18 would be set to a 60-minute daily screen-time limit by default, rolled out in the coming weeks. When a teen reaches the limit, TikTok says they must enter a passcode to keep watching, which it presents as an active choice to extend the time. Teens who opt out and pass 100 minutes in a day are prompted to set their own limit.

The psychological idea

The tool is a default plus a prompt: the limit applies unless changed, and continuing needs a deliberate step. TikTok says it settled on 60 minutes after consulting academic research and experts from the Digital Wellness Lab at Boston Children's Hospital. NPR reported TikTok's head of trust and safety saying there is no collectively endorsed position on the right amount of screen time. Under 13s need a parent or guardian to add 30 minutes.

In practice

No independent evaluation of how much the default changed teens' use was opened for this record. In October 2024 Kentucky's complaint, as reported by the Associated Press, alleged that a TikTok test cut average teen use from 108.5 to 107 minutes a day and that users can easily bypass or disable the tool. NPR, via CNN, reported that the lawsuit alleges executives judged the tool by public trust via media coverage, and that a project manager wrote that the goal was not to reduce time spent.

Why it mattered

The prompt is one of the main company responses to concern about teen screen time, and the filings give a reported, unproven look at how the company may have measured such a tool. The two accounts differ sharply on what the tool was for and how well it worked.

Limits and qualifications

The announcement is company-self-report. The reduction figure and the executives' remarks are allegations in a state complaint, reported by news outlets; this record could not open the complaint, which was sealed after excerpts were published. TikTok said the complaint cherry-picks misleading quotes and takes outdated documents out of context, and that it stands by its efforts. Nothing here shows the prompt's effect on wellbeing. This record gives no medical advice.

Evidence behind the claims

TikTok's newsroom post dated 1 March 2023 said every account belonging to a user below 18 would automatically be set to a 60-minute daily screen-time limit, arriving in the coming weeks.
