I did not meant nsec , sorry for writing it that way what I meant was if your nsec gets leaked or someone out of pure luck got the same nsec and used the same app you are compromised instead why not u...
If that were possible, we could just stop using nostr. It would require for secp256k1 elliptic curve cryptography to be fundamentally broken. (Or a client would have to issue many identities using a broken random number generator but that would still only weaken the keys of the affected users).
