Trezor.io/Start® | Start Your Device Securely | Trezor® — Technical Guide

This technical guide expands on the core steps at Trezor.io/Start® to help security-conscious users, integrators, and engineers initialize Trezor devices, validate firmware, and design operational controls to start your device securely.

Threat model & initial assumptions

When you go to Trezor.io/Start® | Start Your Device Securely | Trezor®, the goal is to eliminate supply-chain and host-based threats during initialization. Assume the host may be compromised and prefer offline/air-gapped initialization for the highest security accounts. Always validate the installer and firmware using checksums and signatures published on the official start page.

Verified initialization workflow

  1. Fetch verified installer: Download from Trezor.io/Start® and verify cryptographic signatures against the release metadata.
  2. Isolate host: Use a dedicated, hardened workstation for device initialization when possible.
  3. Initialize on-device: Create a strong PIN directly on the Trezor hardware; generate and record the recovery seed on physical media — never store the seed digitally.
  4. Verify firmware: Use the official Suite or start page tools to check firmware authenticity before accepting updates.

Operational controls

Record the device serial, firmware version, and enrolling operator in an audit log. For organizations managing multiple devices, maintain a sealed inventory and introduce multi-person custody for seed storage and access to high-value keys. Integrate the Trezor.io/Start® flow into your onboarding checklist to enforce consistency.

CLI & automation guidance

Automation is powerful but dangerous for signing operations. Use the start page (Trezor.io/Start®) for initial setup and reserve automation for read-only operations. If you must automate signing in a test environment, keep secrets out of logs, and require manual approval via device for production signing.

# pseudo-recovery testing (isolated)
# 1. Initialize device following Trezor.io/Start®
# 2. Perform test restore on an air-gapped test device
# 3. Validate address and balances on testnet
