Natanson said she does not use biometrics for her devices, but after investigators told her to try, “when she applied her index finger to the fingerprint reader, the laptop unlocked.”

Use biometric security at your own risk.

Six presses on the power button and iPhones disable biometrics. I believe for most threat models, biometrics is better than typing a passcode, between the hotspots of fingerprints and shoulder surfing risk. Lock out biometrics before sleeping or other leaving unattended scenarios if raids are a risk

Not sure about the laptops; probably best to do a password there.
