The big thing missing from the article is how a device that contains many passkeys is any different from a password manager that enforces security settings. I don’t worry about passwords my password manager generates getting compromised because I use at least 24 random characters (assuming my password manager is using a cryptographically secure PRNG that guarantees some level of randomness, giving us more than 128 bits). Assuming I use that to manage the password to my email, I really only have to worry about my password manager key being compromised. I only used my password manager on trusted devices so I really only have to worry about my trusted devices being compromised.

If I use passkeys, I have to worry about my trusted devices being compromised. According to the article, “as long as you can remember your phone password, you can log in to your accounts.” That sounds like my password manager. The other benefits also sound like a combination of my password manager and privacy focus. I’m not saying this is bad; I just don’t see how it’s different from a security-conscious status quo.
