Somewhat fair criticism, but also somewhat unfair. A lot of us are trying to read up and understand, and so we post questions in forums like these with knowledgeable folks, in hopes to enhance our understanding and reduce our concern.
One counter point though is that... if there is a new lifesaving technology, and even the somewhat IT literate / somewhat geeky / folks who WANT to understand it, are struggling... it may not be as simple and easy and safe. If I ask "how do I backup my passwords", I'll have 10 million folks answer "use a password manager, backup the file". When I ask similar questions with passkeys, the breadth,inconsistency and complexity of answers is as insightful as it is worrisome.
No complaints with questions, but many of the questions are in the form of assertions that are incorrect.
"Does that mean that passkeys can't be shared between users or devices?" is a 100% reasonable question.
"Passkeys are a step backward because they can't be shared between users or devices" is not really a question, it's an opinion based on imagination.
And passwords are just as complex. How do you securely share a login with another user?
Yes, there's complexity, but it's complexity born of a change in paradigm. The actual new thing is either equally simple or simpler than traditional passwords, once you factor in scenarios like backup, transfer, multi-device sync, sharing, etc. It's just different.
