⚠️ **CRITICAL SAFETY NOTE:** Always download software and firmware ONLY from the **official Trezor website** (trezor.io). Never enter your Recovery Seed on a computer screen.
📦 Step 1: Unbox and Verify Authenticity
Before connecting your device, ensure the packaging is tamper-proof and sealed. A genuine Trezor device comes with a security hologram and specific seals that indicate it hasn't been opened.
- Check the seals on the box. If they look damaged or replaced, contact Trezor support immediately.
- Verify all contents are present (Trezor device, USB cable, Recovery Seed cards).
💻 Step 2: Install Trezor Suite
Trezor Suite is the recommended application for managing your wallet. It offers enhanced security and an integrated interface.
- Download the Official App: Go to the official Trezor website (suite.trezor.io) and download the desktop application. **Do NOT use search engines** to find the download link—type the address directly.
- Install and Open: Install the application on a trusted, malware-free computer.
- Connect Device: Plug your Trezor device into your computer using the provided USB cable.

firmware-update">⚙️ Step 3: Install/Update Firmware
Your Trezor will prompt you to install the latest official firmware. This process ensures the device is running the most secure software.
- Confirm on Device: Trezor Suite will show the firmware installation steps. You must confirm the firmware signature and installation directly on your physical Trezor screen.
- Wait for Completion: The device will restart after the installation is complete. **Do not unplug** the Trezor during this process.
🚨 **SECURITY ALERT:** If the device already has firmware installed, perform a **Factory Reset** to ensure there are no pre-existing keys. Follow the on-screen prompts in Trezor Suite.
🔑 Step 4: Create Wallet and Backup Seed
This is the most critical step. The Recovery Seed (usually 12, 18, or 24 words) is the **MASTER BACKUP** of your entire wallet.
- Select 'Create New Wallet': Choose this option in Trezor Suite.
- Write Down Your Seed: The Trezor screen will display the words one by one. **Write them down, in order,** on the provided physical Recovery Seed cards.
- Verify and Store: Trezor Suite may ask you to confirm a few random words. After confirmation, store the card(s) **offline** in a secure, fireproof, and hidden location.
🛡️ Step 5: Set a PIN and Name Your Device
A PIN is required every time you connect your Trezor to a computer. It protects your device if it is lost or stolen.
- Set a PIN: Choose a 4 to 9 digit PIN. The numbers on the computer screen are scrambled, and you enter the corresponding location on the physical Trezor screen. **Do not use easily guessed numbers.**
- Confirm PIN: You will be asked to re-enter the PIN.
- Name Your Device: Give your Trezor a recognizable name (e.g., "MyTrezorHome").
