seeing BitcoinLoveLife's link I just point out that I don't roll dice for seeds. I just encrypt keys with BIP38 for laser edging onto steel plates.
Discussion
And why BIP38? And how do you generate them?
I never evolved past private keys. I don't need a seed phrase to recover an entire wallet if I only use two addresses from said seed. I also still have some legacy addresses. There is several ways to go about this.
One way is to run https://segwitadress.org/ locally, create an address then BIP38 it with a local copy of https://www.bitaddress.org/
