Ludicrous0251FBI Couldn’t Get into WaPo Reporter’s iPhone Because It Had Lockdown Mode Enabled
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.

You can long press the power off button and select lockdown. But biometrics can also be disabled in the settings for unlocking the phone in general but still active for usage when the phone is unlocked, e.g. for banking and 2-factor.
