Does the Fifth Amendment protect phone passwords from police?

Depends on the court — passcodes often qualify as testimonial, but foregone conclusion doctrine kills protection if contents are known.

Are biometrics safer than passwords legally?

No — courts treat fingerprints/face scans as physical, not testimonial, so easier to compel.

Power off to disable biometrics, use strong encryption + long passphrase, invoke Fifth and lawyer up immediately.
