For identities to be truly decentralized, there's no one you could run to to ask permission to change your password. Either you own your identity, or someone else does.

Your identity, BinaryIgor only exists in ycombinator, and for as long as ycombinator allows it, and only ycombinator can allow you to change your password. I can't recall how accounts are created here, but likely it also depends on linking it to your email identity as well. If ycombinator disappears, your identity goes down with it.

My Nickname on Hacker News - yes; but I own this Identity on at least one more platform and my own website, so it's not that simple :) In general, I think given Identity is more about reputation and familiarity that you gain with people by doing or delivering something under particular name in one or multiple contexts/platforms

Doesn't change the fact that Nostr doesn't have a key rotation mechanism
