Attempting to replace passwords with fingerprints && facial recognition is never going to succeed, no matter who tries. There will always be a voiceforous population using the devices that will never consent to using these methods of authentication for privacy or usability reasons (e.g. what happens when you're wearing gloves during winter, or sunglasses), and since Apple is the one implementing this, it's guarranteed to fail because they never look beyond their own product ecosystem.
Hah, I wish I share your optimism. The one thing I know about people is that majority will always choose convenience over safety and I already see people all around me using fingerprint scanner instead passwords whenever they can, and the only reason why it hasn't spread more is because its mostly reserved to more expensive mobile phones&laptops and other tech but soon enough it will spread to lower end and then everyone will use it.
Maybe they get a few million people to use it, but nobody is going to be able to not only force websites to implement such an authentication BUT SIMULTANEOUSLY force users to change their passwords at the same time.
These things don't happen overnight, they are playing the long game.
