I’ve written before about whether a court may order a person to provide a password to a computer or a passcode to a phone to enable an officer to complete a lawful search, such as one pursuant to a search warrant. But passwords and passcodes are so old-fashioned. The cool kids are all using biometric data like fingerprints to secure their devices. So, may a person be required to unlock his or her device using a biometric identifier? Yes, said one court recently.
