Customer identification on sites without passwords and cookies. Is it possible to unambiguously identify site visitors without revealing their personal data and tracking between different sites? Is it possible to abandon the most primitive form of authorization by login/password and the use of cookie/localStorage?
On the one hand, sites need to know the customer in order to, for example, "restore" their settings, product cart, ads, articles, etc. On the other hand, visitors want to remain as anonymous as possible, without revealing their personal data, and without letting third-party sites trace them. And the latter can do this by sharing the data collected among themselves.
