Hong Kong Expands Police Powers Over Electronic Devices Under National Security Law

On 23rd March 2026, the Hong Kong government introduced significant changes to the implementation rules of its National Security Law, expanding police powers over personal electronic devices.

Under the revised provisions, it is now a criminal offence for individuals to refuse to provide passwords or assist in decrypting devices when requested by law enforcement. This applies to all personal electronic equipment, including mobile phones and laptops.

The measures apply broadly to anyone within Hong Kong’s jurisdiction, including residents, visitors, business travellers, and those transiting through Hong Kong International Airport.

In addition, authorities have been granted enhanced powers to seize and retain electronic devices as evidence where they believe there is a link to national security offences.

These changes further reinforce the Hong Kong government’s extensive surveillance and enforcement capabilities, with potential implications for privacy and the handling of sensitive commercial or personal data.
