I for one stay away from any "biometric" ways of authentication. I do 
not want any part of my body "borrowed" from me for such authentication 
;-) But seriously: how secret is your fingerprint? We leave them 
everywhere. Or laptop magically unlocks thanks to face recognition, - I 
don't even want to start rant about that (still: whose brain dead idea 
is that!?)

These days with 2 factor authentication enforced widely we became 
hostages of our cell phones ;-( Imagine you forgot it at home and need 
to authenticate. Or the device just died.

I feel I'm hijacking the thread for my rants...
