Wait a sec. My understanding is that passkeys are public/private keypairs. Public is in server, so even breaking into a server does not reveal the private key.
The big risk with passkeys is storing the passkey where it will be held hostage. Don't store it in most single-ecosystem devices like Apple. Bitwarden can export, and I think 1Password can as well.
Perhaps, but I think volcanic eruption followed by system collapse is very compelling. Here is the story I find most convincing from the experts whose works I have read.
It likely started with a volcanic eruption, leading to widespread famine. Those in western Europe who didn't want to starve migrated en masse, as whole families, becoming the sea peoples. The powerful empires struggled to feed their people, and many were destroyed by the forced migration from the sea peoples. Egypt barely survived, but only as a shadow of itself. Many of the others were destroyed by those who had survived on marginal lands and didn't need complex societies to keep themselves fed.
Iron can't be the cause, as iron weapons pre-existed the Bronze Age collapse. I think the evidence is stronger that the collapse forced widespread adoption. The collapse devastated long-distance trade networks, which cut off the supplies of tin needed to make bronze. The scarcity pushed people to rapidly improve iron smelting.
I'm not a professional historian, but I do find the topic interesting. We should try to learn from past disasters to prevent repetition.

Thanks for the credit, I appreciate it! Glad it was helpful.
I wouldn't call it a "blog post" though, it's simply an essay. I update my essay whenever I decide it needs updating, and "blog posts" are usually chronological and fixed in time once posted.
