Trezor.io/Start | Official Setup Guide

H1 — Before you begin

Unbox your Trezor and check the tamper-evidence packaging. Only use official downloads and official pages listed above. For the canonical "get started" flow use the official start page: trezor.io/start. :contentReference[oaicite:0]{index=0}

What you need

• Your Trezor device and original USB cable.
• A desktop or laptop (recommended) or a supported browser for the web app.
• A private, offline place to write your backup (no phones/screenshots).

H2 — Step 1: Download Trezor Suite (recommended)

For the best experience, download Trezor Suite (desktop or web). Official download and verification instructions are on the Trezor Suite page. Verify the download and signature if you can; this prevents tampered software. :contentReference[oaicite:2]{index=2}

How to install

1. Visit trezor.io/trezor-suite and choose desktop or web.
2. Install the desktop app if you prefer; the web app works too.
3. Plug your Trezor in and follow Suite prompts to install firmware if needed.

H2 — Step 2: Install firmware & initialize device

When you first connect, Suite (or the web start flow) will walk you through installing the device firmware. This is normal: Trezor devices are shipped without firmware and require a first-time installation. Follow on-screen prompts and verify the device authenticity check. :contentReference[oaicite:3]{index=3}

Tips while installing

• Do not interrupt firmware installation (do not unplug).
• Confirm any on-device messages using the physical buttons — never accept an action you did not initiate.

H2 — Step 3: Create your wallet & backup

After firmware, choose Create new wallet unless you are recovering. Suite will show the backup creation flow: write down your wallet backup (recovery seed) on paper or metal and store it offline. Trezor explicitly recommends avoiding digital photos, cloud storage, or text files. :contentReference[oaicite:4]{index=4}

H3 — Backup best practices

• Use multiple copies on different physical mediums (paper + metal plate) in separate secure locations.
• Do not label backups with obvious references to "crypto" or "seed".
• Consider using a metal backup (like KeepKey/KeepSafe products) for disaster resilience.

H4 — Optional: Use passphrase (advanced users)

A passphrase (BIP39 passphrase) adds an extra layer but increases complexity: if lost, funds may be irrecoverable. Treat passphrases as an additional secret — do not store them digitally.

H2 — Step 4: Move coins to your Trezor

Once your wallet appears in Suite and you see receive addresses, send a small test amount first. Confirm the receive address on the physical device screen before copying it — this prevents MITM address substitution.

H3 — Daily use checklist

1. Open Trezor Suite or web app.
2. Connect device and enter PIN on the device.
3. Confirm address on device before receiving.

H2 — Recovery & lost device

If you need to recover a wallet (for example on a new device), use the official recovery flow. The official guide for recovering a wallet on Model One and other devices explains steps and the number-of-words options. Follow the official recovery guide exactly to avoid mistakes. :contentReference[oaicite:5]{index=5}

H3 — If you suspect compromise

If an attacker gained access to your backup, move funds immediately to a new wallet with a new backup. Use a trusted machine and verify Trezor Suite downloads first.

H4 — Support & expert help

If you want help, Trezor offers support articles and paid expert onboarding sessions via the official support site. Use only the official support channels listed above. :contentReference[oaicite:6]{index=6}

H5 — Final checklist before finishing setup

• Firmware installed and device authenticated.
• Wallet backup written and stored offline.
• PIN set and confirmed.
• Trezor Suite installed or web flow completed and verified.
