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

1 Verify the official site

Open your browser and type https://trezor.io/start manually. Confirm the padlock icon (🔒) and exact domain to avoid phishing pages. Never follow random links from social media or unsolicited emails.

Tip: Bookmark trezor.io/start after confirming it to avoid mistyped domains in future.

2 Select your device

Choose between Trezor Model T and Trezor One on the site. Selecting the correct model ensures you receive the right firmware, UI instructions, and device-specific tips during setup.

3 Download Trezor Suite

Click the official download link to get Trezor Suite (Windows, macOS, Linux). Suite is the desktop application that communicates with your device and provides transaction management, firmware updates, and account views.

Only download from suite.trezor.io or the link provided on trezor.io/start.

4 Install & launch

Run the installer package and open Trezor Suite. The app will detect your device when connected. On Windows, accept driver installation if prompted. Avoid running Suite as administrator unless required by OS policies.

5 Connect your Trezor

Use the supplied USB cable and plug the Trezor directly into your computer — do not use untrusted USB hubs for the initial setup. The on-device display will show a welcome screen; follow prompts on both Suite and the device.

6 Firmware installation

If requested, allow Trezor Suite to install the latest firmware. Firmware is signed and verified; it protects your device against tampering. Keep the device connected until the update completes — do not unplug mid-update.

If a firmware verification error occurs, stop and contact official support at trezor.io/support.

7 Create or recover wallet (critical)

Choose Create New Wallet if you're new, or Recover Wallet if you have an existing seed. The device will generate a recovery seed (12–24 words). Write the words down manually on the supplied recovery card — do not photograph or store them digitally.

Store the seed offline in at least two secure locations.
Consider a metal backup plate for fire/flood protection.
If recovering, enter the seed only on the device — never on a computer.

8 Set PIN & passphrase

Set a PIN to protect access to your device. Optionally enable a passphrase for an additional hidden wallet. The PIN entry and passphrase confirmation occur on-device to prevent interception by malware.

9 Confirm transactions on-device

Trezor requires physical confirmation for each operation. Always verify recipient addresses and amounts shown on the device — this prevents man-in-the-middle attacks where software attempts to change transaction details.

10 Finalize & maintain

After setup, use Trezor Suite to manage accounts. Regularly update firmware & Suite, keep backups secure, and follow safe computing practices (antivirus, OS updates, avoid public Wi-Fi for critical actions).

Advanced tips & best practices

Beyond the core setup, here are practices that increase long-term security and usability:

Redundancy: Keep multiple physical copies of your recovery seed in separate secure locations (e.g., home safe + safety deposit box).
Passphrase caution: A passphrase increases security but must be remembered precisely. Losing it means losing access to funds in that hidden wallet.
Third-party integrations: You can pair Trezor with software like MetaMask (via Trezor Bridge) for DeFi access — always confirm actions on the device.
Privacy: Use coin control or Tor when required for privacy-sensitive operations available in Trezor Suite.
Emergency plan: Create a clear, documented process for heirs or trusted parties to recover assets if needed — consider legal and security tradeoffs carefully.

Action	Why it matters
