How to Start Up Your Trezor Device — Independent Setup Guide

Important — Safety first: This article explains how to initialize and use a Trezor hardware wallet (Model One & Model T). It is an independent resource and not authored by SatoshiLabs or Trezor. Always download software and firmware only from the official source (visit the official site directly — do not follow links from email or social media). Never share your recovery seed with anyone.

Why use a hardware wallet?

Hardware wallets such as Trezor protect your private keys by keeping them isolated inside a secure device. While exchanges and software wallets can be convenient, they introduce online attack surfaces. A hardware wallet reduces risk by signing transactions on the device itself, so your private keys never leave the unit.

Before you begin — checklist

Your Trezor device (Model One or Model T) — unopened packaging preferred.
USB cable included with the device (or OTG adapter for mobile).
A computer or supported mobile device with internet access.
Pen and paper or a metal backup plate for your recovery seed — avoid storing seeds digitally.
A private, distraction-free place to write down your seed.

Step-by-step: initialize your Trezor

Unbox & inspect: Confirm the seal and packaging look untampered. If anything appears abnormal, contact the vendor or support before proceeding.
Connect the device: Use the included USB cable to connect your Trezor to a computer or compatible mobile device. The device will power on and show a simple welcome screen.
Open the official management app: For the safest experience use the manufacturer’s official app (desktop or web) to perform setup and firmware installation. Do not install unknown third-party wallet software. Search for the official software by typing the vendor domain directly into your browser or use the vendor’s verified download page.
Install firmware if prompted: New devices or devices reset to factory settings may need official firmware. Follow on-screen instructions in the official app to install it. Firmware ensures the device runs trusted code and is essential for security.
Create a new wallet: In the official app choose “Create new” (or similar). The Trezor will generate the keys internally and display prompts. Follow these steps on the device screen rather than trusting the computer to display critical values.
Write down your recovery seed: The device will generate a recovery seed (usually 12, 18, or 24 words). Write these words down, in order, on paper or a metal backup. Number each word. DO NOT take photos, store the seed in cloud storage, or type it on an internet-connected device.
Set a PIN code: Choose a PIN to prevent unauthorized access to the device. Avoid obvious patterns. The PIN should be long enough to make brute forcing impractical.
Optional — add a passphrase: Advanced users may layer a passphrase on top of the recovery seed. This creates a hidden wallet that cannot be recovered with the seed alone. Use this only if you understand the implications: if you forget the passphrase, funds are irretrievable.
Verify backup & finish: Many apps ask you to confirm one or more seed words to verify you copied them correctly. Complete this step and keep your physical backup secure.

Security best practices (must read)

Never share your seed: Anyone with your seed can steal your funds. Treat it like cash.
Keep backups offline: Two or three physical copies in separate, secured locations reduce single-point failure risk (fire, theft, flood).
Confirm addresses on the device: When you sign a transaction, always verify the receiving address on the Trezor screen — not just on your desktop.
Beware phishing: Bookmark the official site and never follow emailed links to update firmware or enter your seed.
Consider a metal backup: Paper can burn or degrade; metal backup plates resist fire and water.

Common questions

What if I lose my Trezor?

As long as you have your recovery seed, you can restore your wallet on another compatible hardware wallet or supported software wallet that accepts the same seed standard. Without the seed, funds are lost.

What if the device is stolen?

If the thief does not have the seed or the PIN, your funds remain safe. If you suspect the seed was compromised, transfer assets to a new wallet whose seed you control.

Do I have to use Trezor Suite?

The official management tool is recommended for the most direct, secure experience. Advanced users may use compatible third-party software, but only when they fully understand compatibility, trust, and the risks involved.

Are firmware updates mandatory?

Firmware updates often include security patches and new features. Installing official firmware is strongly recommended. Only install firmware offered by the official source.

Daily usage tips

Use the smallest number of wallets/accounts you need — complexity increases user error risk.
Label accounts clearly in your management app so you don’t confuse addresses.
For large holdings, consider multi-signature setups with multiple hardware devices.
Practice restoring from your recovery seed on a spare device to ensure backups work (do this carefully and offline).

Advanced features (overview)

Depending on the model, features may include:

Shamir Backup (split seed backups)
Hidden wallets via passphrase
Support for many cryptocurrencies and coin-specific accounts

Research each feature thoroughly before enabling; some features (e.g., passphrases) increase protection but also increase the risk of permanent loss if mismanaged.

Final checklist before you finish

Have you written your seed down clearly and stored it in a safe place?
Is your device running official firmware?
Have you set a PIN and understood optional passphrase implications?
Have you bookmarked the vendor’s official website and downloaded software from there?

If you answered yes to each question, your device is ready for secure use.
