Are there alternatives to HTTP Cookies?

Question

Browsers

Good afternoon, I ran into a problem when writing an analytics system with the fact that a certain percentage of users lose cookies. I would like to know if it is possible to replace them with something, given that this system will work on several sites i.e. localStorage, webSQL, etc. Thank you.
PS
Essence of the question: you need to store "tokens" somewhere for a long time

Answer 1

Evercookies , for example. And Browser fingerprinting in general.
Moreover, some users specifically clear cookies and other storage. They also use adblock/ublock, noscript, ghostery, request policy, turn on private mode, use proxies, VPNs and Tor, install whonix, and so on. If only to complicate this analytics.
