On March 23, 2026, Hong Kong changed the implementing rules relating to its National Security Law. In national security cases, refusing to provide passwords or assist with decryption to give police full access to personal electronic devices is now a criminal offense.

The requirement covers devices such as cellphones and laptops. It applies to foreigners, including U.S. citizens, whether they are in Hong Kong, arriving there, or only transiting Hong Kong International Airport.

The changes also give authorities greater power to seize and retain personal devices they claim are linked to national security offenses.
