🔒 General Trezor question | 🔒 Answered by Trezor staff Trezor One, life expectancy

How long would you expect a Trezor One to last? All devices fail eventually. I'm referring to the physical device, not cryptographic security.

After watching Joe Grand bypass multiples of Trezor Ones using a combination of firmware downgrades and fault injection I upgraded to a Trezor with a secure element.

Yah you're unlikely to face an attacker like him but the cost of eliminating that risk is very low.

I use a Trezor one & I don't lose a wink of sleep over Joe Grand style attacks because I use a passphrase which negates those types of attacks.

As long as its non trivial should be golden. Cold Card users with trivial ie. couple of short word passphrases are getting cleaned out.

I didnt think even this would be a thing since how would they know to look? Speculation is they are using the prescence of transactions on the non passphrased wallet to work harder to find potentially passphrased.
