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

Trézor.io/Start is the official setup gateway for initializing your Trezor hardware wallet safely and securely. Whether you have just unboxed a new Trezor Safe 7, Model T, or Model One, this page guides you through downloading the official Trezor Suite application, installing firmware, and creating your wallet with confidence. This guide walks you through each step of the setup process while highlighting the security practices that protect your digital assets.

Why Trezor.io/Start Is the Only Safe Starting Point

Security begins with authenticity. Visiting Trezor.io/Start ensures that you download the genuine Trezor Suite application directly from the manufacturer and avoid phishing sites that mimic official branding . Fake setup pages are common and designed to capture your recovery seed phrase — the master key to your crypto .

Trezor Suite is available for Windows, macOS, and Linux as a desktop application, and as a web app at suite.trezor.io/web for users on ChromeOS or those who prefer browser access . Mobile users can download Trezor Suite Lite for Android and iOS to track portfolios and manage assets on the go .

Downloading and Installing Trezor Suite

Desktop Installation (Windows, macOS, Linux): Navigate to the official Trezor Suite page and select Download for desktop . Choose the version matching your operating system. Windows users need Windows 10 (64-bit) or newer, while macOS requires version 12 “Monterey” or higher .

When downloading on Windows, your browser may display a warning stating “Trezor Suite.exe was blocked because it could harm your device.” This is a false positive related to changes in Trezor’s Windows certificate. To proceed, click the three-dot menu next to the blocked file, select Keep, and confirm by clicking Keep anyway . During installation, Microsoft Defender may ask for confirmation — verify that the publisher is Trezor Company s.r.o. and click Run anyway .

Web App Access: Users on ChromeOS or those who cannot install software can access Trezor Suite directly at suite.trezor.io/web . Note that Firefox and Safari are not supported due to lack of WebUSB functionality.

Verifying Your Download: For maximum security, Trezor provides GPG signatures allowing you to verify the integrity of your download before installation . This ensures the file has not been tampered with during distribution.

Connecting Your Trezor Device

After installing Trezor Suite, connect your Trezor hardware wallet using the supplied USB cable . The application will detect the device and perform an authenticity check. Do not continue if this check fails — it may indicate a counterfeit or tampered device .

Since Trezor devices ship without firmware, Suite will prompt you to install the latest signed firmware. This step ensures your device is running the most secure and up-to-date software .

Setting Up Your New Wallet

Once your device is connected and firmware is installed, select “Create new wallet” if this is your first time setting up .

Choosing Your Backup Type: Newer Trezor Safe models allow you to choose between a 12-word and a 20-word backup, while older models default to different lengths . A 20-word backup can later be upgraded to a multi-share backup for advanced security, while a 12-word backup stays single-share only .

Recording Your Recovery Seed: Your Trezor device will display your recovery seed phrase on the device screen only. Write down each word in the exact order given. Never type this phrase into a computer, phone, or website — it should only ever appear on the device screen . Never photograph it or store it in cloud notes, email drafts, or messaging apps . Write it on paper or a metal backup plate and store copies in at least two separate physical locations .

Confirming Your Backup: The device will ask you to confirm specific words to verify your backup is accurate . This step ensures you have correctly recorded the phrase before any funds are stored.

Setting Your PIN: Create a strong PIN using the scrambled on-screen keypad. This PIN protects your device from unauthorized physical access .

Adding Accounts and Managing Crypto

After setup is complete, Trezor Suite displays your accounts and balances . To add cryptocurrency accounts, navigate to the Accounts section and select the coins you want to manage, such as Bitcoin, Ethereum, or Solana .

Receiving Crypto: Select the account and click Receive. Copy the address or scan the QR code. Always verify the address on your Trezor device screen before sharing it .

Sending Crypto: Select Send, enter the recipient’s address and amount, then confirm the transaction on your Trezor device. Every transaction requires physical confirmation, ensuring that even if your computer is compromised, your assets remain protected .

Security Best Practices

Never Share Your Recovery Seed: Trezor support will never ask for your recovery phrase. Treat any request for it as a scam attempt, regardless of who claims to be asking .

Verify Transaction Details on Device: Before approving any transaction, read the details displayed on your Trezor device screen. Blind-signing — approving transactions without reading them — has cost users large sums .

Keep Firmware Updated: Regular firmware updates improve security, add new features, and maintain compatibility with supported assets .

Buy from Official Sources: Always purchase Trezor devices directly from the manufacturer or a listed authorized reseller. Secondhand devices carry real risk of tampering .

Troubleshooting Common Setup Issues

If Trezor Suite does not detect your device, try a different USB cable (some cables are charge-only), use another USB port, or restart the application . On Windows, running Trezor Suite as administrator can resolve permission-related connection problems.

For ChromeOS users, remember that the desktop version cannot be installed — use the web app at suite.trezor.io/web or the mobile app .

Summary

Starting at Trezor.io/Start ensures you download the official Trezor Suite, verify your device, and set up your wallet securely. The process involves installing the application, connecting your hardware wallet, generating and recording your recovery seed offline, and adding accounts. With Trezor Suite and a Trezor device, you gain full self-custody over your digital assets while keeping private keys completely offline.
