If your device was purchased from the official Trezor Shop, Amazon storefront or an authorized reseller, it is most likely safe to use.
Never buy a Trezor from an unauthorized third party, as you can never tell who may have had access to it before you.
As a first step, you should check if your package is complete and has not been tampered with.

In addition to the holographic seals, there are other security measures that will verify the security of your Trezor device:
- All Trezor devices are distributed without firmware installed - you will need to install it during setup. This setup process will check if firmware has already been installed or not. If firmware is already installed the device should not be used.
- The bootloader verifies the firmware signature each time you connect your Trezor to a computer. Trezor Suite will only accept the device if the installed firmware is correctly signed by SatoshiLabs. If unofficial firmware has been installed, your device will flash a warning sign on its screen upon being connected to a computer.
- You will need to generate a recovery seed during Trezor device setup. This seed is unique, ensuring only you have access to your private keys.
