🎃 Stark +053 (Fearful) 🏴‍☠️ on Nostr: Is there a NIP for keychains, where nostr would recognize everything from a given key ...

Is there a NIP for keychains, where nostr would recognize everything from a given key as being from another key with linked permission?

So you could have a primary key you only use once to link 2 other keys, one for everyday use and one you keep buried or locked in a safe for redoing the linking process if the other one is ever compromised.

Whenever you log into nostr, you enter your currently active everyday use key, but nostr displays your activity as coming from the original key.

Or could any login functionality work along the lines of a derivation scheme like BIP 44/49/84/87 ❓

No, you would white list in a non-forgeable way what your next npub will be so when your key is compromised you can move to it regardless of what the attacker does

NIP-41 if you want the whole thing
