Under Hong Kong's new national security regulations, police now have the authority to seize electronic devices such as phones and tablets and demand passwords from suspects in national security cases.

Password or prison: In Hong Kong, refusing to unlock your phone is now a crime

Refusing to hand over passwords can result in up to one year in prison and a fine of HK$100,000 (approximately US$12,773). Providing false information carries a penalty of up to three years in prison.

The law applies to everyone, including travellers and those transiting through Hong Kong International Airport, according to warnings issued by the US State Department.

Authorities will also be able to retain personal belongings as evidence in national security cases and expand their surveillance and detention capabilities.

The changes build on the National Security Law enacted in 2020, which broadened government control and expanded the scope of criminal offences.
