This is yet another example of why I'm not a fan of saving a seed on a hardware wallet. Every secure element will eventually get hacked, meaning you'll need to upgrade again and again.

There's a better way.

With a device like Krux or SeedSigner, you can save your seed on a QR code that you scan in order to load your seed. There's no need for a secure element chip or even a PIN code to unlock the device since there's nothing saved on the device. Plus, it's fully airgapped.

And with Krux, you can save your seed as an encrypted QR. If somebody finds your encrypted QR, they can't scan it without the decryption key.

If somebody steals your device? No worries. There's nothing on it. And if you use an encrypted QR, no worries if somebody finds it. They can't scan it without the decryption key.

Best of all, the encryption is open source. It's industry standard CBC encryption with as strong of a decryption key as you choose. You can even save your decryption key as a QR.

Companies that make hardware wallets are never going to use the Krux/SeedSigner way of loading seeds via QR because they make money through hardware sales and upgrades. "Oh, no! Last year's secure element chips have been hacked! Better upgrade to the latest model!" It's ridiculous, but I don't blame them. It's a business model that works. I don't have to worry about any of that though. I never save my seed on a device.

Pro Tip! There's a fork for SeedSigner that enables encrypted QRs too.

Makes you wonder how difficult it would be to make a QR and software that gave 3 different seeds.

1) Fully unencrypted, but valid, this way if someone finds it they get whatever little amounts of crypto you had on it. (Hot wallet)

2) Encrypted and you have to enter a password to get that seed. (Warm wallet)

3) Encrypted, but you have to scan with a different piece of software and enter a password that then generates another QR code that you then scan with something like Krux (cold storage)

Might be more Rube Goldberg then really needed but seems like an interesting concept.
