Hong Kong can force device passwords from travelers, with imprisonment and fines

Hong Kong requires people questioned to surrender device passwords under threat of imprisonment and fines up to HK$100,000.

The law covers all nationalities and can apply to people transiting through Hong Kong; customs can seize items deemed to have seditious intent.

Possessing an encrypted device or being authorized to access a device can create liability; providing false or misleading information can carry up to three years' imprisonment.

The updated law draws much of its framework from mainland China influence.

Similar powers exist elsewhere: U.S. border law revisions allow detention and device seizure, and Australia and the U.K. also have device‑unlocking requirements and seizure/forensic inspection powers.
