Trézor® — Getting Started: Start Up Your Device

A friendly, step-by-step guide to set up your Trézor® hardware wallet, create a backup recovery seed, and safely manage your crypto.

Overview

Welcome! This guide walks you through powering on your Trézor® device, verifying its authenticity, creating a secure PIN, recording and verifying your recovery seed, and connecting to Trézor Suite (desktop or web). Follow each step carefully — the security of your funds depends on the seed and how you protect it.

Important: Never share your recovery seed, PIN, or passphrase with anyone. Trézor support will never ask for your full recovery seed.

Before you start

  1. Buy from an authorized seller — Only purchase Trézor devices from the official store or authorized resellers. Check the serial number and tamper evidence when unboxing.
  2. Prepare a secure workspace — Work in private, away from cameras and on a clean surface. Have a pen and the included recovery card or a durable backup like metal plate ready.
  3. Have a computer or smartphone ready — Trézor Suite (desktop or web) will be used to finish setup. Ensure OS is updated and you have a current browser (Chrome, Edge, or Firefox).
  4. Don't plug in unknown cables — Use the cable included with your device or a high-quality cable that fits correctly. Avoid charging cables from unknown sources if possible.

Unboxing & inspection

When your Trézor device arrives:

  • Inspect the packaging for tamper evidence (seals, sticker integrity).
  • Ensure the serial number on the device matches any number on the packaging.
  • Make sure the accessory kit (cables, recovery card, quick start) is present.
If anything looks suspicious: Do not use the device. Contact the seller or Trézor support immediately.

Initial setup: Power on & firmware

This section covers powering on, confirming authenticity, and installing or confirming firmware.

1. Power on

  1. Connect the USB cable to your computer or supported mobile device and the Trézor device.
  2. The device will display a welcome screen. Follow on-device instructions — never trust instructions that appear only on the computer screen.

2. Verify device authenticity

Trézor devices perform a built-in authenticity check. You will be asked to compare a word or code shown on the device to one shown in Trézor Suite. Do this carefully and confirm on the device itself.

Do not accept any authenticity messages that only appear on your computer and not on the device.

3. Firmware

If the device needs a firmware update, the update will be delivered through Trézor Suite. Install updates from the official app only. Firmware updates are signed and verified by Trézor.

4. Create a device PIN

The device will prompt you to choose a PIN. Choose a PIN you can remember but that is not easily guessable. The PIN is entered using the device screen (not your computer) for additional security.

Tip: Use a length of at least 6 digits if possible. Longer is better.

Write down your recovery seed (the single most important step)

The recovery seed (also called backup seed or mnemonic) is the master key to your wallet. If you lose your device, the seed restores your funds on any compatible wallet.

1. What to expect

Trézor generates a 12-, 18-, or 24-word seed (12 is common for many devices). Words are shown on the device screen only — never on your computer. You must write them down in order, exactly as shown.

2. How to record it

  1. Use the supplied recovery card or a durable metal backup plate.
  2. Write each word clearly and in order. Use block letters if handwriting is messy.
  3. Store the written seed in at least two geographically separate secure locations (e.g., safe deposit box, home safe).
  4. Consider using a stainless steel backup (resists fire, water, corrosion) — there are well-known solutions for engraving or stamping words onto metal.

3. Never store the seed digitally

Do not photograph, email, screenshot, or store your seed in cloud services, password managers that sync to the cloud, or text files. These are common attack vectors for thieves and malware.

4. Seed verification

After writing your seed, the device will ask you to confirm random words from the seed to verify that you recorded them correctly. Perform this verification without help from the web or phone.

5. Optional: Passphrase (Advanced)

Trézor supports an optional passphrase that augments your seed to create additional hidden wallets. Only use a passphrase if you understand its implications — if you forget it, the wallet is unrecoverable even with the seed.

If you use a passphrase, treat it like another secret: never store it with the seed, and consider storing it separately (different vault or secure memory).

Connect to Trézor Suite (desktop & web)

Trézor Suite is the official interface for managing coins, firmware, and settings. Download it from the official site or use the official web version.

  1. Install Trézor Suite: Go to suite.trēzor.io or download the desktop app from the official Trézor website.
  2. Open the app: The app will guide you through device recognition and pairing. Follow on-device prompts to confirm actions.
  3. Add accounts: In Trézor Suite, add the cryptocurrency accounts you want to manage (Bitcoin, Ethereum, ERC-20 tokens, etc.).
  4. Receive test funds (recommended): Send a small test amount to each new address to confirm everything works before sending large amounts.
When sending transactions, verify transaction details on the device screen before approving — this is how you ensure the computer or malware cannot silently alter recipients or amounts.

Security best practices

  • Physical security: Keep your device and seed in locked, secure locations. Limit who knows about your holdings.
  • Keep firmware current: Install trusted firmware updates via Trézor Suite to benefit from security fixes and features.
  • Phishing awareness: Always confirm domain names and never enter your seed anywhere. Trézor support will never request your seed.
  • Multi-backup strategy: Use multiple seed copies stored safely and consider geographically separated backups to protect against theft, fire, or other disasters.
  • Use passphrase carefully: If you choose to use a passphrase, document your process, and test recovery in a safe environment.

Troubleshooting & common issues

Device not recognized

Try a different USB port or cable, reboot your computer, and ensure Trézor Suite is up to date. Verify that your operating system supports the device.

Missing firmware or update failed

Reconnect the device and follow Trézor Suite instructions. If a firmware update fails, do not share your seed — follow the official recovery steps in the app.

Forgotten PIN

If you forget your PIN, you will need to reset the device. You can restore from your recovery seed on the same or a new Trézor device.

Seed compromised

If you believe your seed has been exposed, move funds to a new wallet with a freshly generated seed immediately. Use a new Trézor or compatible hardware wallet and new backups.

FAQ

Q: Can I use my Trézor with a smartphone?
A: Yes — some mobile devices support Trézor via USB OTG or Bluetooth (model dependent). Check the device documentation for compatibility.
Q: What if my device is lost or stolen?
A: Your funds are safe as long as your recovery seed is secure. Use the seed to restore your wallet to a new device.
Q: Is it safe to use my wallet on a public computer?
A: Avoid public or untrusted computers. If necessary, use a live OS boot disk and verify the environment, but best practice is to use a trusted computer.
Q: Can I use third-party wallets with my seed?
A: Yes, your BIP-39/BIP-44 compatible seed can be used with other compatible wallets — but only if you understand the implications and trust the software.
