Hong Kong authorities have revised enforcement rules tied to the Hong Kong National Security Law, making it a criminal offense to refuse police demands for access to personal electronic devices, according to a recent government update.
Under the changes, individuals in Hong Kong, including foreign nationals and travelers in transit, can be required to provide passwords or other decryption assistance to law enforcement. The measure applies to all electronic devices, including mobile phones and laptops.
The updated rules also grant police expanded authority to seize and retain devices as evidence if they are deemed connected to national security offenses.
The provisions apply to those entering, leaving, or passing through the territory, including at Hong Kong International Airport.
The changes were announced on March 23, 2026, and are part of the broader legal framework governing national security enforcement in the region.
The US Department of State issued guidance advising American citizens in Hong Kong to be aware of the updated rules. The agency stated that individuals who are arrested or detained should contact the U.S. Consulate General Hong Kong & Macau.
The State Department also encouraged travelers to enroll in the Smart Traveler Enrollment Program (STEP) to receive alerts and facilitate communication with US officials while abroad.
The revised enforcement measures expand police powers related to digital access and evidence collection under Hong Kong’s national security framework.
