Welcome Lizz Nakamoto - Anon Innovator to Nostr. She is a shared identity that can be used by people who want to share cool Cypherpunk projects anonymously. Usually, this is quite a big problem, because if you want to share open source code and want to stay anonymous, you can't use your existing social network.
The password to posting is going to be shared widely among devs. If you are a free software and cypherpunk author (even if not anon), ask for password and spread it wisely.
We want the anonymity set to grow, plus it's not defined, it's just the knowledge of a password. So it can't be really pinpointed who knows it.
On the other hand, there is a password, otherwise the account would be just taken over by spammers, reducing usefulness.
Lizz is accessible through Nostr (give her a follow) and you can also access her website for people who are not Nostr enabled yet. Through the web you can also easily post, the Nostr private key is derived from the password in JavaScript.
