What if you don't use password but use a cryptosteel kind of solution, but you cut your seed into half, and engrave the first part on one steel (it can be a steel business card, you can find it on eg. ebay) and the second part on another steel.
A half of a seed can be enough to crack the whole seed, depending on attacker's capabilities. Electrum seeds have 135 bits of entropy, and 67.5 bits can be cracked on modern hardware.
Plus, you are making things harder for yourself by having parts of your seed in different places. There are better schemes for that like Shamir's Secret Sharing or good old multisig - they even allow N of M parts setups, so you can account for risks of losing some of the parts of the wallet.
That's good to know, thank (the cracking of the seed)
Well, just make 3 or 4 parts and spread it
I know that's a bit oldschool solution, but I'm not familiar with that passphrase.
I know that Electrum has a possibility to use a password, also Trezor and maybe Ledger Nano has also something similar (Trezor for sure), but I don't know if they are cross compatible or not.
If you just want to store an amount in a wallet (even in a normal address not segwit etc... just the old style solution which is compatible with all kind of wallets for now and forever
) you don't want to use any possible incompatible solution just to increase the security.
Multisig is another good solution, I'll have a closer look at it, thanks
