In the United States, social media service TikTok faced many bans due to national security concerns.
As of June 2023, federal employees and state employees in 34 (out of 50) states are prohibited from using the app on government devices.
In May 2023, Montana became the first state to ban TikTok on all personal devices, though this will not take effect until January 1, 2024, and is being challenged in court.
