ooh looks likely.. great supporting post!
not a fan of the approach where a company hides facts "we used established science and knowledge to productise a thing, but we like profit so we'll obscure the science"
google search got dumb on purpose, a whistleblower called it out - if you spend longer look on the search pages they get more "engagement" time out of you....
they were trying to get out of the Find Out part of the timeline, i think the suggestion is that we're in the prequel movie where we are Fucking Around.
sure, you can use a passkey as a primary authentication, but only "a device" or "system"(keypass/1pass etc) knows the passkey detail.
with only passkey, if my passkey provider/ device is compromised then everything is lost. having single factor auth seems like a bad idea.
a password is something that I can know, so is still useful as a protection mechanism.
having two factor auth should include password and passkey, which seems entirely reasonable whilst also providing an easier path forward for people used to TOTP.
in school you learn how to do 2 + 2 and understand why it is 4.
its not the actual answer that is the goal, its the understanding of why it is so and how the steps are applied to get the answer.
knowledge layered on knowledge happens over years of learning, but eventually you know some stuff about things that people already learnt before you.
as the saying goes- this isn't rocket surgery, people!
make it real for your dad - every chance you get, capture the price of a few things and chart it out over time... actual real evidence that you collected yourself is harder to refute than a graph produced by anonymous sources online.
finally!! :D
