When you purchase a Trezor device (such as a Trezor Model One or Model T), the first action you’ll be instructed to take — on the device’s screen — is to go to trezor.io/start. This website walks you through downloading official software, installing firmware, securely generating your wallet, and protecting your crypto assets.
Why start here? Because there are countless phishing and fake websites pretending to be official setup tools. Typing or scanning the QR code to trezor.io/start manually ensures you are on the legitimate site and not being tricked into revealing your secrets.
Why a Hardware Wallet Matters
Before we go into the setup steps, it’s helpful to understand what makes Trezor different from a typical software wallet or keeping crypto on an exchange:
🔐 True Self‑Custody
With a Trezor hardware wallet:
Your private keys — the cryptographic keys that control your crypto — are stored only inside the device.
They are never stored on your computer, phone, email, or cloud storage.
🛡️ Protection Against Hacks
Software wallets and exchanges are constantly online, making them targets for hackers. With a hardware wallet, even if your computer is infected with malware, your private keys stay inaccessible because the Trezor signs transactions offline inside its secure chip.
💡 Phishing Risks
If you accidentally visit a fake setup site and follow its instructions, you could unknowingly send your keys to scammers. The trezor.io/start site protects you by providing only official, secure instructions and downloads.
What You Need Before You Begin
Before you visit trezor.io/start, make sure you have:
A brand new, sealed Trezor device (Model One, Model T, or Safe 5). Never use pre‑owned devices.
A USB cable (usually provided in the box).
A computer with a modern browser — Chrome or Chromium‑based browsers work best.
A stable internet connection.
A quiet, private space to write down your recovery phrase securely.
Also, double‑check the package seals to make sure the device has not been tampered with. If anything looks suspicious, stop and contact Trezor support before plugging it in.
Step‑by‑Step Guide: Using Trezor.io/Start
The setup process via Trezor.io/Start is designed to be intuitive, secure, and safe from common mistakes. Let’s break it down:
Step 1: Visit Trezor.io/Start
Open your browser and type trezor.io/start into the address bar. Do not click links from emails, ads, or social media — those are common phishing attempts.
This will redirect you to the official Trezor setup flow and show options to download the official management app.
Step 2: Download and Install Trezor Suite
Once on the Start page, you’ll be prompted to download Trezor Suite — the official desktop application for managing your wallet. It works on Windows, macOS, Linux, and also has mobile support.
Trezor Suite is the interface you use to view balances, manage assets, send and receive transactions, and update firmware. It’s safer than web‑only tools because it communicates directly and securely with your device.
Important: Always download software only through the Start page — never from third‑party sources.
Step 3: Connect Your Trezor Device
Now, plug your Trezor into your computer using the cable. Your device will display messages and prompts that correspond with the software steps.
The Suite will automatically detect your Trezor and begin the setup.
Step 4: Update or Install Firmware
If your device is brand‑new, you’ll be asked to install the latest firmware — the internal software that runs the device. This is recommended for optimal security.
Firmware updates are cryptographically signed, meaning the device verifies authenticity before installation. Never install firmware from unofficial sources.
Step 5: Create a New Wallet
Once firmware is up to date, you’ll be asked to choose between creating a new wallet or recovering an existing one. For first‑time users, choose Create New Wallet.
This step generates your wallet’s private keys directly inside the device. These keys never leave the device, and are the cryptographic backbone of your wallet.
Step 6: Write Down Your Recovery Seed – The Most Important Step
This is the critical part:
The device generates a 12, 18, or 24‑word recovery phrase.
You must write it down by hand — never photograph or store it digitally.
Store this written seed in a safe, offline location (like a safe or fire‑proof box).
This phrase is the only way to restore your wallet if your Trezor is lost, stolen, or damaged. If you lose this seed without any backup, you permanently lose access to your crypto.
After writing down all words in the correct order, the software typically asks you to confirm a few of them on the device screen to ensure accuracy.
Step 7: Set a Strong PIN
Setting a PIN adds another layer of physical security. Each time you connect your Trezor, you’ll be asked to enter this PIN code.
Safe PIN practices:
At least 6 digits long
Avoid obvious patterns like 123456
Keep it private and never written with your recovery seed
If someone enters a wrong PIN too often, many Trezor devices impose delays or even wipe the device entirely — requiring seed recovery. This protects against brute‑force attacks.
Step 8: Explore Trezor Suite
Once setup is complete, you’re ready to use your Trezor with the Suite dashboard. Here you can:
View wallet balances and transaction history
Send and receive crypto securely
Add new cryptocurrency accounts
Label accounts and organize assets
Enable advanced features like passphrase security
Whenever you send transactions, Trezor will prompt you to confirm details on the device’s screen before signing. This ensures the computer cannot fake transaction details, even if compromised.
Managing Crypto After Setup Receiving Funds
To receive crypto:
Select the asset (BTC, ETH, etc.) in the Suite.
Click Receive to generate an address.
Verify the address on your Trezor screen before sharing.
If the on‑screen address doesn’t match what’s shown in Suite, this is a red flag — do not proceed.
Sending Funds
Sending works similarly:
Enter the destination address and amount.
Verify it on your device screen.
Confirm to sign the transaction.
Troubleshooting & Tips Device Not Detected
If Suite doesn’t detect your Trezor:
Try another USB port or cable.
Restart the computer or Trezor Suite.
Firmware Prompts Reappear
This may happen if your device reset or was wiped. You can reinstall firmware and recover your wallet using your seed phrase.
Security Best Practices
Never store your recovery seed digitally — no screenshots, emails, cloud storage, or photos.
Never share your seed with anyone — not even Trezor support.
Avoid phishing sites — always remember trezor.io/start.
Consider advanced features like passphrases for extra security.
