Security benefit appears strongly overstated. Compared to using a password manager (including generated secure passwords for each account), there isn't a significant security benefit. passkeys require using a manager as well, so there isn't much point.

All people are stupid sometimes. A security flow that doesn't account for this very well isn't a very good security flow.

(Related: everyone tends to be unlucky eventually, and, unfortunately, everyone becomes incapacitated/dies eventually. Security flows need to account for these as well. Not to mention that in my experience, no software company continues to offer a quality service at a reasonable price forever. You're lucky to get 10 years. Having access to my accounts tied to a single piece of software is likely to become a big pain at some point.)

No they don't. I use hardware passkeys for all my important accounts. It's extremely easy.
