💡 **New Device Checklist**
Before connecting, verify your Trezor has: 1) A holographic seal or tamper-evident sticker intact. 2) No pre-set PIN. 3) No pre-generated Recovery Seed card. **If any are missing, STOP and contact Trezor support immediately.**
Step 1: Install Trezor Suite
The **Trezor Suite** application is the secure, dedicated interface for managing your device and assets. **Do not** use third-party web wallets for initial setup.
- **Download:** Go directly to the official Trezor website to download the latest desktop application for your operating system (Windows, macOS, or Linux).
- **Verify:** Cross-check the application signature/checksum for maximum security before installation.
- **Connect:** Launch the Suite and connect your Trezor device using the provided USB cable. The Suite will automatically detect the device.

Step 2: Generate Your Recovery Seed
The Recovery Seed (12, 18, or 24 words) is the **master backup** of your wallet. This step is the **most critical** for long-term security.
- **Confirm:** The Trezor Suite will prompt you to create a new wallet. Confirm the action on your Trezor screen.
- **Write Down:** Carefully write the words onto the **provided physical Recovery Seed card** in the exact order shown on your Trezor's screen.
- **Store Securely:** Once verified, **disconnect** your Trezor. Store your physical seed card in a **fireproof, waterproof, and private location**. Never photograph or digitize it.
Step 3: Create a Strong PIN
Your **Personal Identification Number (PIN)** protects your Trezor from unauthorized physical access if it is lost or stolen. It's an essential layer of protection.
- **Input:** The Trezor Suite will display a random pattern of dots. You will use your Trezor device's screen to map the numbers to the grid on your computer screen.
- **Complexity:** Use a strong, memorable PIN of **6 to 9 digits**. Avoid simple patterns or birthdays.
- **Confirmation:** You will be asked to enter the PIN a second time to confirm. **Do not** write your PIN down with your Recovery Seed.
