really nice @gandalf21. zero knowledge PW managers like keeper are starting to use elliptic curve cryptography in practice. keep up with the education! there are many uses for this practice and privacy implications (ie: voting) that will have experiments and need to be discussed over the next 2 decades

hey OP -

for some, it's unnerving to have a seed phrase that can be discovered or forcibly taken. and splitting it also introduces issues. MPC with keyparts isn't quite ready for retail (like zengo), but a dual factor seed phrase is intriguing...

if you write about the passphrase - a word that works in tandem with your seed phrase - this "seed phrase password" (part of BIP 39) would fit quite well within the context of presenting steps to secure a seed phrase
