Before visiting Trezor.io/start, ensure your hardware wallet is genuine and tamper-free. The box should come factory-sealed, with hologram stickers intact. Trezor develops its devices with strict security standards, so any visible sign of tampering should be treated seriously. Avoid using any hardware wallet that appears compromised or was not purchased from an authorized distributor.
Once confirmed, connect your Trezor Model One or Trezor Model T to your computer using the provided USB cable. Modern computers recognize the device quickly, enabling you to proceed to the setup.
