That BIP-39 code is built into Trezor, my Mycellium wallet, and every wallet that Drago mentioned. It is the industry standard way of generating private keys. You don't have to use the code at that link manually. It's already in the HW and SW wallets.

However if your really wanted to, you could use it to create separate paper wallets with each key or a paper wallet, potentially several pages, of private keys.

But as I say, you don't have to. Your paper backup can be the 12 random words making up the seed phrase. When you are ready to use that backup, buy another Trezor if you lost the old one, or buy another BIP-39 HW wallet. Or download a free wallet app that you trust (I don't have any special knowledge other than I trust mycellium for now). As long as it supports BIP-39 you can recover your keys.

As long as it supports BIP-39 you can recover your keys.

Thanks, I just would like to have as many ways to recover as possible.

I will let you know how my test run works.

One last question: As long as I am buying one, is there any advantage of the Trezor Model T over the Trezor Model one for my limited needs. (I am going to hodl it indefinitely and will not be spending any of it.)
