Not more vulnerable than if they were just using password. You're still missing my point, password managers do not give you the ability to just copy-paste the private key of a passkey into a form field, unlike passwords. Some don't give you access to it at all (*cough* Apple *cough*). Sure you can get the private key if you have access to the password managers vault, but that's not what's being talked about. Common usage patterns matter immensely in security. At the end of the day, the attack surface for passkey-based authentication is smaller than password-based authentication, which is a step in the right direction.

The parent made a blatantly false and dangerous statement and then followed it up with a question. Did we read the same comment?
