trezor.io/start — Secure setup and best practices

Welcome to the Trezor start guide. This page provides a concise, formal introduction to initializing your Trezor device, generating and protecting your recovery seed, and applying security best practices that reduce risk. If you are new to hardware wallets, follow the recommended steps precisely to ensure cryptographic keys remain under your exclusive control.

Begin by visiting trezor.io/start over a secure connection (HTTPS). Use a computer you trust, confirm the device's authenticity and firmware version, and follow the on-device prompts. Never share your recovery seed — the only backup of your private keys — and avoid storing it in digital form. Prefer physical, tamper-evident storage in multiple secure locations.

This guide emphasizes security-in-depth: device integrity, secure communication, safe backup, and careful transaction verification. On the technical side, websites implementing guidance from trezor.io/start should enforce HTTPS, set strict HTTP headers (HSTS, CSP, X-Frame-Options), and avoid loading third-party scripts unnecessarily. Server-side controls are the most effective protective measure — consider Content-Security-Policy headers and secure cookie flags (Secure; HttpOnly; SameSite=Strict).

If you operate a wallet-supporting site, restrict resources to trusted origins, minimize inline scripting, and apply Subresource Integrity (SRI) when external resources are required. Always favor permission prompts and explicit user consent for any sensitive action, and maintain accessible, clear instructions so users can validate each step.

For more advanced users, leveraging a separate, air-gapped machine to store recovery materials or using hardware-enforced passphrases increases resilience against theft and remote attacks. Should you suspect compromise, follow the recovery and seed-rotation procedures immediately.
