Starting up your Trézor device is an intentional, secure process designed to protect your crypto from the very first moment. Over the next few minutes you'll power the device, create a new wallet or restore an existing one, and learn best practices for keeping your recovery phrase and device safe. This guide is platform-agnostic and works whether you're using Windows, macOS, Linux, or a mobile companion app.
Open the box and examine the tamper-proof seal. The package should include the Trézor device, a USB cable, recovery sheets, and an instruction leaflet. Inspect packaging for unusual tapes, scratches, or signs of pre-use. If anything looks off, stop and contact Trézor support.
Connect your Trézor to your computer using the supplied USB cable. The device will power on and display a short welcome screen. On your desktop, open Trézor Suite or the recommended web setup at Trézor.io/start. Follow the on-screen prompts. During setup the device and the application will verify each other using a secure handshake — this ensures you are talking to your device and not a malicious intermediary.
You will be offered two primary choices: Create a new wallet or Recover an existing wallet. Choose Create to generate a brand new cryptographic seed on the device. The Trézor generates randomness and stores seed material only inside the device — it never leaves the hardware.
Next you'll set a PIN. Choose a PIN that is long, memorable to you, but not easily guessable. The PIN protects the device if someone gains physical access. Trézor displays randomised numbers on-screen for PIN entry, preventing fingerprint smudges or camera-based attacks from revealing your PIN input pattern.
This is the most important step. The recovery phrase (typically 12, 18, or 24 words depending on your device settings) is the only way to restore access to your funds if the device is lost or damaged. Write the words exactly as shown, in order, on the provided recovery card or on secure metal backup options sold separately. Store the written backup in a safe location — ideally a fireproof, waterproof safe or bank deposit box.
Once setup completes, Trézor Suite will show your wallet dashboard. You'll be able to receive and send coins, review transaction history, and connect to supported third-party apps. Always verify transaction details on the physical Trézor screen before approving — never rely solely on your computer display.
Q: Can I set up Trézor offline?
A: The device generates seed material internally and does not require internet to create the recovery phrase. You can perform the core initialization offline if you prefer, but the Suite app will need network access for certain features like fetching balances.
Q: What if I lose my recovery phrase?
A: If you lose the recovery phrase and your device is lost or damaged, you will not be able to recover your funds. Always keep backups and consider using multiple secure locations.
Q: How do I verify firmware updates?
A: Use the official Trézor Suite or Trézor.io resources to check for updates. The device will prompt and verify any official update before installation.
