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.

between the hotspots of fingerprints and shoulder surfing risk

If ICE is close enough to you to shoulder surf you, they are close enough to manhandle you, shove you and “”“assist”“” you into touching your privates (aka biometrics).
