This is why I hate when I get a 1Password prompt to reenter my nonbio password at inopportune times in a public place. My keystrokes can be secretly filmed from a distance. When I gain access to passwords that I copy and paste by fingerprint, the forcible theft of my machine puts me at near 0 risk. (My preferred way to login while in public.)
They'll take your phone, so can't trigger the killswitch.
Of course, from experience, this does not matter if they do compel you to give up the password by other means (e.g. threatening to harm your family).
How else do you protect against the exploit of security cameras, anywhere you unlock your phone, recording your passcode?
Your face and fingers are always with you and it's easy to force you to open your phone.
You can "forget" a password but not your face.
