edit: I think I’ve misunderstood the point of the article. He is saying passkeys are dangerous for people without password managers, therefore for most people passwords are still better (since most people don’t use password managers). It’s not so much a problem with passkeys, but the lack of password managers.
Even in the best case scenario, where you’re using an iPhone and a Mac that are synced with Keychain Access via iCloud
Surely the better-case scenario would be using a password manager?
The article doesn’t address the recommended use-case of passkeys + password manager, which makes it kind of irrelevant.
