Btw, does Trezor have an official name for the feature? I am pretty sure it isn't 'SD Protect.' I started referring to it that way, seeing your recent posts. Isn't it something like 'PIN Protection' or 'PIN Encryption?'

According to the first article published by them, they called it "SD card protection".

When this feature is enabled in the command line (trezorctl), it is referred to as "SD protection":

Activating and using the SD protection

To enable this feature you will need trezorctl version 0.11.6 or later and a FAT32 formatted microSD card.

If the card is not properly formatted, then Trezor will offer to erase and format the card for you.

There are three commands related to SD protection:

trezorctl device sd-protect on

trezorctl device sd-protect off

trezorctl device sd-protect refresh

I personally prefer SD card protection or MicroSD Card Protection.

I generally don't use it, but it's a protection more focused on safeguarding against unauthorized physical access to the device. So for those interested in using it, it's a great idea. As long as you don't lose the encrypted SD card.

In any case, in the event of losing the PIN code or the SD card that carries the secret attached to the PIN, it's always good to have the wallet backup securely stored for emergencies.
