i wonder if machine learning could do this better
   finetune a model to generate huge lists of possible passwords, using a
   database as a train/test set, success being producing lists that
   contain real passwords with greater likelihood
   could stretch the data some and extend training by rerandomizing the
   token mapping
   -
   maybe a solution to all this would be to bind user-specific passwords
   to user-specific secret keys.  could have the password "houseguest"
   work for 5 devices or such.  I wonder what other protocol improvements
   have been proposed.
   ... router could use its antenna to identify who you are and what you
   are doing from your biosignals using classification models.  wave of
   the future.
