I see FROST talk, so let me dig up this post.

Nostr, where your puritanical attitude towards cryptography dies in the name of dirty disgusting revolting pragmatism and convenience.

Now, I have copy-pasted and cleartext .txt-file stored many bitcoin keys in my days, but nothing as absurd as how I have treated my nsec thus far. There may be a solution that is great, if only we take our sensibilities to a dark alley and shoot it in the face.

FROST is a threshold multi-signature scheme that allows you to take your Nsec, and turn it into a multi-sig where a majority needs to coordinate in order to create a valid signature under your Npub.
Check out a demo here (don’t actually use this): https://join.the-nostr.org/.
It is simple: you put in a nsec, and you get a bunker URL back. Subsequently you can schizo-store the smashed in steel nsec away deep inside the tunnel network underneath your home, and instead copy paste that URL into all those different Nostr clients.
Lost your URL? Or did the service go down? No problem! Just venture back into those tunnels, re-acquire your nsec and create another set-up at another service elsewhere, easy. Did your URL get compromised? Ask the signers to stop cooperating and reset the multi-sig.

Obviously you run the risk that the signers you made part of the multi-signature scheme collude and compromise your secret. But honestly, in a world where you are supposed to keep a secret superduper safe, but also are expected to use it all the time; getting to a point where the ‘keep it superduper safe’ becomes a lot easier because what you ‘use all the time’ is some derivative in a trusted set-up that can be swapped out, might just be an actual step forward.

Ceterum censeo Carthaginem esse delendam.
