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

Welcome to the official setup guide. This page leads you through every step needed to safely initialize and use your Trezor® hardware wallet. Read each section fully before proceeding — your attention now prevents loss later.

Prepare: your environment and tools

Before you open the box, pick a private, tidy workspace where you won’t be rushed or photographed. Gather a charged computer or mobile device with internet access, the supplied USB cable, and a pen. Use the supplied recovery card or a dedicated notebook — never digital note-taking for your recovery seed.

Essentials checklist
  • Trusted computer or phone (no public terminals)
  • USB cable included with the device
  • Pen and recovery card or secure notebook
  • Private, well-lit area

Unbox: inspect the package

Open the package carefully. Trezor® packaging includes security elements and tamper-evidence. Inspect for broken seals or signs of tampering — if suspicious, stop and contact official support at trezor.io/support. Verify the device model and included accessories match the documentation in the box.

Connect and verify the official website

Connect your Trezor® to the computer using the supplied USB cable. In your browser, navigate directly to trezor.io/start. Do not follow links from emails or social media. Confirm the site uses HTTPS and that the certificate is valid. The official start page will guide you to the recommended Trezor Suite or web-based setup flow.

Security reminder: Never enter your recovery seed into a website, app, or chat. The recovery seed must remain offline at all times.

Install Trezor Suite (recommended)

Trezor Suite is the official interface for managing accounts and interactions. Download it from the official start page, install it, and launch it. Choose Set up new device and follow the on‑screen prompts. Suite performs authenticity checks, firmware installation, and guided initialization.

Authenticate your device

During the initial connection, Trezor® devices perform a built-in authenticity check. Trezor Suite will display a verification challenge you must match on the physical device screen. Never bypass or ignore this confirmation — it ensures the device you hold is genuine and not a tampered unit.

Firmware: when and how to update

Firmware is the secure operating layer on your Trezor®. If a firmware update is available, Trezor Suite will offer it during setup. Accept and install firmware updates from the official Suite only. During the update, follow on‑device instructions and do not disconnect the device until the process completes. Unofficial firmware or interrupted updates can put your device at risk.

Create a PIN

Creating a PIN secures your device against immediate physical access. Choose a PIN that balances memorability with unpredictability. When entering the PIN, the device shows a randomized number layout so that keystroke logging on your computer cannot reveal the PIN. If you forget the PIN, the only recovery method is wiping the device and restoring from your recovery seed.

Generate and record your recovery seed

The recovery seed (usually 12, 18, or 24 words) is the master key to your funds. The device will display the words one-by-one; write them down exactly in order on the provided recovery card. Do not store the seed digitally (photos, cloud, password manager). After recording, double-check the spelling and order. If you lose this seed and the device is lost or damaged, funds cannot be recovered.

Never share your recovery seed: No one from Trezor® or any legitimate service will ever ask for your seed. Requests for it are scams.

Confirm the recovery seed

To ensure an accurate recording, the device will request confirmation of random words from your seed. Complete this on the device — the confirmation guarantees you copied the seed correctly. Only continue the setup once the device accepts your confirmations.

Optional: set a passphrase (advanced users only)

A passphrase acts as a 25th word that creates an additional hidden wallet. It makes your setup much more secure but also more complex: a forgotten passphrase means your funds are unrecoverable even if you have the recovery seed. Use a passphrase only if you understand this trade‑off. Never store the passphrase with the seed.

Using your Trezor®: receiving, sending and address verification

After setup, open Trezor Suite or a compatible wallet to add accounts (Bitcoin, Ethereum, etc.). Always verify receiving addresses on your Trezor® device screen before sharing them. When sending, verify the transaction details — amount and recipient — on the device’s display. The on‑device screen is the final authority; the computer screen can be compromised by malware.

Troubleshooting & recovery scenarios

Device not recognized

Try a different USB port and cable, restart your computer, and ensure Trezor Suite is up to date. If the device still isn’t recognized, consult official support.

Forgot PIN

Forgetting your PIN requires wiping the device and restoring from your recovery seed. That’s why safe storage of the seed is critical.

Seed lost or damaged

If the recovery seed is lost and you no longer possess a functioning device, coins are unrecoverable. Plan before acting: never use a single, vulnerable copy for large holdings.
