Any bullying or power abuse situation may easily exploit biometric authentication against the victim. Kids bullying other kids, domestic abuse, authorities etc.
Now, if biometric authentication becomes the norm, how will a wife suffering domestic abuse justify using a password?
I agree with you, but am not sure a password works too well in such situations either - the abuser would presumably just beat the victim until they enter their password?
However, I think touchID is susceptible to being robbed since if you have your bank account or Apple Pay enabled to transfer cash with touchID as authentication, then you can be robbed while you’re passed out drunk or roofied or whatever.
