Trezor.io/Start – How to Set Up Your Trezor Device Safely

Why set up Trezor correctly?

A hardware wallet like Trezor stores your private keys offline. Proper setup prevents theft, loss, and accidental exposure of your recovery seed. This guide gives practical, security-first instructions to get you from unboxing to receiving your first transaction with confidence.

What you'll need

• Your new Trezor device (Model One or Model T).
• A computer (or supported mobile device) with a USB port and an up-to-date browser.
• A secure, private workspace away from cameras and strangers.
• A pen and the printed recovery card that may ship with the device — or a secure metal backup solution (recommended for long-term storage).
• Patience: setup takes under 15 minutes but security steps are worth the time.

Step 1 — Unbox and verify the device

Before you plug anything in, check the packaging. Factory seals should be intact. If the device shows signs of tampering (broken seals, loose screws, visible damage), contact the seller or manufacturer — do not proceed.

Step 2 — Connect and initialize

1. Go to trezor.io/start on your computer or mobile browser. The website will guide you to the correct app for your model.
2. Connect the Trezor to your device using the supplied USB cable. Follow on-screen prompts to install the official Trezor Bridge or use the web app (the site will advise you what’s needed).
3. When prompted, install the latest firmware if the device requires it. Firmware updates are signed by Trezor; only install updates shown by the official site.
4. Choose Create a new wallet when asked. Never accept a pre-configured recovery or allow anyone else to provide the recovery phrase for you.

Step 3 — Create and secure your recovery seed

The recovery seed (a series of words — typically 12, 18, or 24) is the single most important piece of information. It can restore your wallet on another device. Protect it like a bank vault key.

1. Write each word exactly as it appears on the device, in order. Use the supplied recovery card or high-quality paper if you must, but consider a metal backup for fire/corrosion protection.
2. Never store the recovery seed digitally — not in photos, notes, cloud storage, or password managers.
3. Never share the seed. No legitimate support representative will ever ask for it.
4. After writing the seed, the Trezor will ask you to confirm select words — this verifies your backup.

Step 4 — Set a PIN and optional passphrase

A device PIN protects the Trezor if it is stolen. Choose a PIN you can remember but that isn't guessable from your personal details.

1. When prompted, set a PIN on the device. The PIN is entered using randomized digits on the Trezor screen — this prevents keyloggers from capturing it.
2. Optional: enable a passphrase (also called a 25th word). A passphrase adds another secret on top of the recovery seed and creates an independent hidden wallet. Use a long, memorable sentence. Remember: if you lose the passphrase, funds are unrecoverable even with the seed.

Step 5 — Install apps and receive crypto

Trezor supports many cryptocurrencies via the Trezor Suite or compatible wallets. Use only verified wallet apps and follow these steps to receive funds:

1. Open Trezor Suite (or the recommended wallet by the official site) and connect your device.
2. Create or add an account for the currency you want to receive (e.g., Bitcoin, Ethereum).
3. Generate a receive address from the device and confirm it matches the address shown in the browser/app before sharing it with anyone.
4. Send a small test amount first to confirm everything is working, then send the full amount.

Frequently asked questions

Can I set up the device without internet?

You can initialize the device offline for certain models, but firmware installs and wallet apps generally require an internet connection. Always verify firmware signatures via the official app/website.

What if I lose my recovery seed?

If you lose the seed and the device is damaged or lost, you cannot recover funds. That’s why multiple secure backups are critical. If you still have access to the device, create a new wallet and back it up immediately.

Is it safe to buy a used Trezor?

Buying a used hardware wallet is risky unless you can factory-reset and update firmware securely. Prefer buying from authorized retailers or directly from the manufacturer.

How do I keep my device firmware up to date?

Check Trezor Suite or trezor.io/start for official firmware updates. Only apply firmware shown by the official site/app that is cryptographically signed by the manufacturer.

Final notes & next steps

Setting up your Trezor correctly is the best defense against most digital theft vectors. After setup:

• Practice sending and receiving small test transactions.
• Store one backup seed in a separate secure location.
• Consider using multi-sig or a second hardware device for large holdings.
• Keep software and firmware updated and periodically review your security practices.
