Nah - they could alternatively use a honeypot to try and trick you - aka the Rick and Morty episode M. Night Shaym-Aliens!... or they could just make your life pain until you're able to successfully unlock your thing - even if it's a password you can't communicate verbally it is something you can communicate since your computer can understand you.

Biometrics come with the same potential issue - great, now instead of beating me up until I tell them the password is rosebud they're going to cut off my thumb - this scenario is so much better.

I'd rather get hit by a wench than a wrench, if I am gonna get hit by something. Death by Snu Snu is preferable to death by blunt trauma- at least I get something out of it.

Depends on the hiring process. A good innkeeper will hire wenches who can muster a good punch: it's a competitive world, you don't want downtime from bar brawls and stuff.
