I'm curious why no nostr clients (native or web) support username/password detection by browsers or password managers like bitwarden.

In other words, why is it that when I log in to a client or "sign up" and generate a new npub+private key, my browser and/or bitwarden extension don't ask to save the credentials?

This could go a long way towards making key management more convenient and secure.
