When using a Trezor, it's important to use the passphrase option which is a 25th seed word that will alter the internal hash used to generate your wallet addresses. If the firmware isn't compromised, you can still lose all your money if you lose the device if someone happens to have the skill and $100 of electronic equipment to read the internal board.
BTW, you misspelled Trezor as tezor in the keywords section. It could affect visibility of the post.
Is it really worth someone's time to steal my Trezor when they have no idea how much money is on it? Also, they have to hack it before I realize it's missing. Tough sell. It would be a lot easier to get access to the seed phrase backup. No hacking required.
The seed phrase backup is no use if they don't also have the passphrase protecting that seed.
Ah yes, true. But if you have the passphrase memorized, why not just do yourself a solid and memorize a full 12 word seed? :D
I'd try not to admit that in public because if the TSA finds out, you might have to undergo a lobotomy to cross imaginary borders.
My memory is too poor to even attempt such a thing, unfortunately.
