I think their biggest weakness is the vendor lock in. Using a 3rd party password manager is the best solution for most people, so they arent locked to their phone. But they are right in saying none of it is quite ready. I think the article is forgetting, they are password replacements, not account recovery replacements. Realistically, people are just as likely to forget a password, and account recovery proceedures still have to be in place. I dont see the issue there. Passkeys are good they are just being pushed before properly fully developed, but we are slowly getting there.
