Until passkeys can pass the test of "my non-technical friends and family don't call me for help about them", passkeys aren't ready. Vendors keep making assumptions about how users behave which are not safe assumptions, and that keeps blowing up the interactions of non-technical users. (I'm sure there's an "assumptions developers make about user accounts" blog out there somewhere.)
For example, my family has had to call me for help on the interaction between passkeys on Apple & Amazon multiple times. They have a shared Amazon account, which neither Amazon nor Apple seem to like. The first problem came when they didn't even know they'd been moved to passkeys - there was a popup that one of them didn't understand, they clicked OK to get it to go away, and suddenly the other partner can't log in, and neither of them can figure out how to log into Prime Video on their AppleTV. Another time one of them got "nudged" to add a fingerprint to the account, again freezing out the other person.
Until that nonsense stops happening, Passkeys aren't ready.
By that metric, passwords are even less ready, as I seem to always have to field calls for passwords getting stolen or compromised or accounts getting phished. I guess we're back to faxing ID.
I have a non-technical father with dementia, and passwords+TOTP are almost frictionless for him, with minor exceptions. We are able to share around passwords and TOTP codes without any problems so I can properly monitor his online activities to keep him out of trouble. Heβs a cranky old guy with almost zero trust, so having to input all that stuff satisfies him that security is being employed.
