Regarding the Seed Signer...even if you have some other signing device (regular hardware wallet like ColdCard, Ledger, etc), you'll always have a seed phrase backup, right?

And the backup would be stored/hidden in whatever way you think is best for your situation. So, I don't see that backing up a Seed Signer seed phrase is necessarily any different from backing up a ColdCard seed phrase. Am I missing something?

I do agree that, especially as bitcoin becomes more valuable and people start understanding what it is, having a list of 12 words anywhere that's remotely available/visible is a horrible idea. Obfuscating them somehow seems critical.

Here's a like with a list of potential concerns/considerations for using SeedSigner: https://github.com/SeedSigner/independent_custody_guide?tab=readme-ov-file#alright-but-theres-got-to-be-a-catch-right
