I sincerely hope not since, as a recent HN submission pointed out, you [EDIT] possibly [/EDIT] lose all 5th amendment protections in the US when your device is no longer protected by "something you know"
"As well as" == fine
"Instead of" == run!
"As well as" == fine

The cynical part of me thinks that the proliferation of mobile devices + the close proximity of these new devices to danger (danger being people who would quite like you to give them access at every opportunity it seems. e.g. employees of an increasingly privacy-hostile government, such as the police) in the hands of users who don't know the implications is the biggest change/problem.
