Forcing suspects to reveal phone passwords is unconstitutional, court says

Context & Ripple Effects
This 2015 ruling planted the flag that compelled phone passwords are testimonial acts protected by the Fifth Amendment — and the five years of coverage since show courts refusing to converge. Florida went the other way within a year, allowing investigators to demand an iPhone passcode (Florida's passcode ruling), while Pennsylvania's top court later reversed an order that had forced a child-porn suspect to hand over his computer password (Pennsylvania's reversal).
The battleground has since shifted from passwords to every new way of getting past a lock screen: a 2019 federal ruling denied authorities compelled biometric unlocking even with a warrant (the biometrics ruling), a 2020 decision treated merely powering on a phone to view its lock screen as a search requiring one (lock-screen-as-search), and New Jersey contradicted Indiana months apart on the same core question (New Jersey's contrary finding). Each ruling redraws the boundary case by case rather than settling it.
First-order effects
- In jurisdictions following this line, prosecutors lose the ability to order suspects to divulge passcodes, pushing investigators toward forensic extraction tools or seizing devices unlocked before arrest.
- Courts must now classify each unlock method separately — typed passcodes read as testimonial, while biometrics and lock-screen access get adjudicated as distinct legal questions.
Second-order effects
- Opposite outcomes from state supreme courts like New Jersey and Indiana create circuit-level conflict, raising the pressure for a higher authority to resolve whether compelled decryption is ever permissible.
Third-order effects
- If the split holds, constitutional protection for encrypted devices will depend on geography rather than principle, and the law will keep lagging behind each new authentication mechanism — password, fingerprint, face — until a definitive ruling forces uniform treatment.
The trend: US courts are piecing together, state by state and unlock method by unlock method, whether compelled device decryption violates Fifth Amendment protections against self-incrimination.
