Re: Is it safe to use the Trezor Safe 5 even on an infected computer or mobile ?
I don't understand, can you please try explaining again? Do you mean that trezor suite connected to Model One, will receive the pin I enter? Do I enter the pin on the hw wallet device or do I enter the pin on computer that have trezor suite? You said Model One has a randomized keypad. Is that keypad on the hw wallet device or is it on trezor suite? It sounds very strange that trezor suite would be able to know what the pin is. There would be no reason to buy a Model One, it defeats the purpose of buying a hw wallet. Model One sounds like a medium warm or lukewarm wallet, not entirely hot wallet but not entirely cold wallet.
You seem to be confused about how the Trezor One PIN works, I'll try to clarify: we have a matrix of dots that appear on the screen of the connected device/computer (host) and on the Trezor One display the actual position of the numbers is displayed, you just need to click (on the connected computer) on each of the dots that represents the correct order of the numerical matrix on the Trezor One display.Currently, you can set a PIN with up to 50 digits on Trezor One.
