Thanks for the quick response @emlun - 

As I understand, let say user registration on `foo.com` creates a blob in the authenticator for `foo.com`. iframes of `foo.com` embedded on different sites using the `blob` in the authenticator `foo.com` can track users across sites. 

Let me know if I'm missing something.
