Trézor.io/Start® — Starting Up™ Your Device | Trezor

What Is trezor.io/start?

trezor.io/start is the official onboarding page for setting up a new Trezor hardware wallet (such as Trezor Model One or Trezor Model T). It guides users through:

  • Installing Trezor Suite
  • Updating firmware
  • Creating a new wallet
  • Backing up the recovery seed
  • Setting a PIN and optional passphrase

It is the recommended and safest way to initialize your Trezor device.

Step-by-Step: How to Use trezor.io/start

Unbox and Inspect Your Device

  • Make sure packaging is intact and tamper-evident seals are secure.
  • Only use devices purchased from official or authorized sellers.

Visit the Official Website

Download Trezor Suite

You will be prompted to download Trezor Suite for:

  • Windows
  • macOS
  • Linux

Trezor Suite is the official desktop app used to manage your crypto securely.

Install Firmware

If your device is new, firmware may not be installed.

  • Trezor Suite will prompt you to install the latest official firmware.
  • Confirm installation directly on your Trezor device screen.

Create or Recover a Wallet

You can either:

  • Create a new wallet
  • Recover an existing wallet using your recovery seed

Important: Recovery Seed Backup

During setup, you will receive a 12- or 24-word recovery seed phrase.

This is the most important step.

  • Write it down on paper (never store digitally).
  • Do NOT take screenshots.
  • Do NOT upload to cloud storage.
  • Store it offline in a secure location.

Your recovery seed is the only way to restore your wallet if the device is lost or damaged.

Set a PIN Code

After backing up your seed phrase:

  • Choose a strong PIN
  • Confirm it directly on the device
  • The PIN protects your wallet from unauthorized physical access

Optional: Add a Passphrase

Advanced users can enable a passphrase:

  • Adds an extra hidden wallet layer
  • Works like a 25th word
  • Must be remembered exactly

If forgotten, funds cannot be recovered — so use carefully.

What Happens After Setup?

Once setup is complete, you can:

  • Send and receive cryptocurrency
  • Manage multiple coins
  • Track portfolio balances
  • Connect to supported third-party wallets
  • Use advanced security settings

All transactions must be physically confirmed on your Trezor device.

Security Tips

  • Only use the official site: trezor.io
  • Never share your recovery phrase
  • Trezor support will NEVER ask for your seed
  • Beware of fake websites and phishing emails
  • Keep firmware updated
