Look, at best, Passkeys shift your logins from your head to OS-supplied keychain management. Whether they do attestation today or not, they big, industry-wide effort to move away from "what you know" (i.e. username/password) + "what you have" (2FA) towards "platform-authenticates-you-to-website automatically" has both security benefits and lock-in risks.

Maybe it was too strong to say the were a "trap", but it is also too strong to say there is no worries here.

That is your choice as the user. You can use the default credential manager that is offered out of box, or you can use your own.
