Trezor Start Guide: Initializing Your Hardware Wallet

Your secure journey begins here. Follow these critical steps to set up your device.

CRITICAL SECURITY WARNING: Never enter your Recovery Seed (12/24 words) on a computer or phone. Only enter it directly onto the Trezor device if prompted, or write it down on the provided paper card.

Phase 1: Preparation and Connection

Step 1.1: Unbox and Verify

  • Check the physical packaging for any signs of tampering, tears, or previous opening.
  • Ensure the holographic seal is intact and shows no damage.
  • Unpack the Trezor and the USB cable.

Step 1.2: Connect to Trezor Suite

You must use the official Trezor Suite application or web interface.

  1. Go to the **official** Trezor start page.
  2. Download and install the **Trezor Suite** desktop application, or choose the web version.
  3. Connect your Trezor device to your computer using the supplied USB cable.
  4. Launch Trezor Suite. The application will detect your new device.

Phase 2: Firmware Installation

Step 2.1: Initial Firmware Download

A brand new Trezor requires the latest firmware for full functionality and security.

  1. The Trezor Suite will prompt you to install the firmware. Click **'Install Firmware'**.
  2. **Verify the fingerprint** on your computer screen matches the one displayed on your Trezor device. This is a critical security step.
  3. Confirm the installation on your Trezor device itself. The process will take a few moments.
  4. Your device will restart once the firmware is successfully installed.

Phase 3: Wallet Creation and Backup (The Most Important Step)

Step 3.1: Create New Wallet

Choose the option to **'Create New Wallet'**. Do not choose 'Recover Wallet' unless you are restoring an existing one.

Step 3.2: Generate Recovery Seed

  1. You will be prompted to create a **Recovery Seed**. This is a sequence of 12, 18, or 24 words (depending on the model).
  2. Prepare the paper Recovery Card provided in your box.
  3. The words will be displayed **ONLY** on the screen of your Trezor device.
  4. Carefully and accurately write down each word in the correct order on your paper card. **Double-check your spelling.**
  5. Store this paper card in a secure, fireproof, and private location. **Anyone who finds this card can take your funds.**
NEVER DIGITIZE THE SEED: Do not take a photo of your Recovery Seed, do not save it on your computer, cloud, or phone. Keep it offline and physical only.

Phase 4: Setting Up a PIN and Naming

Step 4.1: Establish a PIN

Your PIN protects your device from physical theft. The digits on your Trezor screen will be randomized.

  1. Trezor Suite will show an abstract 3x3 grid.
  2. The numbers will be displayed on your **Trezor screen only**.
  3. Look at the physical Trezor to see where the numbers are located, then click the corresponding positions on the 3x3 grid on your computer screen.
  4. Set a PIN of 4 to 9 digits. Confirm it a second time.

Step 4.2: Name Your Device

Give your Trezor a simple, memorable name (e.g., "MyMainTrezor"). This is for your convenience and does not impact security.
