What are Trezor security features

For sure, as the device is bought directly from us, everything should be genuine and legit. However, there are a few security measurements with Trezor that can be checked.

  • Trezor One has a security hologram placed on the box. Trezor T over the port, these should be intact so you can be sure no one was manipulating with the device earlier.

  • All Trezor devices are distributed without a firmware software, so you need to install it for your first use. If there is a firmware installed already, then that means that someone used this device before you.

  • The bootloader verifies the firmware signature. The device only runs if the firmware is correctly signed by SatoshiLabs.

  • Because the recovery seed is generated during Trezor setup, there is no default seed, only the seed you will generate for yourself. If you encounter any Trezor device with pre installed firmware that was purchased as new, please let us know.
