Hong Kong Can Force Travelers to Unlock Phones and Bitcoin Wallets

Hong Kong authorities have declared a new rule requiring individuals to unlock phones and laptops during national security investigations. Refusal to comply will be treated as a criminal offense. The rules also allow police to seize and retain devices they deem relevant to such cases, including at airports and border checkpoints. Although widely shared posts frame this as a new change, these powers stem from the National Security Law introduced in 2020. However, the renewed attention is triggering concern across the crypto industry. Hong Kong: On March 23, 2026, the Hong Kong government changed the implementing rules relating to the National Security Law. It is now a criminal offense to refuse to give the Hong Kong police the passwords or decryption assistance to access all personal electronic devices pic.twitter.com/gK1xQvzK6K TravelGov (@TravelGov) March 26, 2026 Bitcoinholders face a specific risk. Many users store private keys, seed phrases, or wallet access on personal devices. If authorities compel access, that data could be exposed, potentially giving full control over funds. As a result, crypto users and security professionals are warning against traveling to Hong Kong with sensitive wallet data. The law applies broadly, including to foreign nationals and transit passengers, and national security remains loosely defined. This shifts the risk profile beyond political cases. Traders, founders, and retail investors carrying self-custody wallets could all be affected if devices are inspected. Consequently, the guidance is becoming more direct. Avoid storing wallet credentials on travel devices, or avoid high-risk jurisdictions altogether. For Bitcoin holders, device access is no longer just a privacy issue. It can translate into immediate financial exposure.
