Carefully unbox your Trezor device and ensure all components are present: the Trezor hardware wallet, USB-C cable, recovery seed cards, and lanyard. Before proceeding, verify the holographic security seal is intact and shows no signs of tampering. This physical verification ensures your device hasn't been compromised during shipping or storage. Authentic Trezor devices feature unique security elements that protect against counterfeiting and supply chain attacks.

Visit the official Trezor website at trezor.io/start to download Trezor Suite, the dedicated desktop application for managing your device. Always verify you're on the genuine Trezor website to avoid phishing attempts. The desktop application provides enhanced security features not available in the web version, including local data processing and reduced attack surface. Trezor Suite is available for Windows, macOS, and Linux operating systems with automatic update functionality.

Connect your Trezor device to your computer using the provided USB-C cable. The device will automatically power on and guide you through the initialization process. You'll be prompted to install the latest firmware, which is crucial for security updates and new features. Never skip firmware updates as they often contain critical security patches. The initialization process takes approximately 5-10 minutes and ensures your device is running the most secure software version available.

This is the most critical security step in the setup process. Your Trezor device will generate a unique recovery seed phrase, typically consisting of 12, 18, or 24 words. Write these words down in exact order on the provided recovery seed cards using a permanent pen. Store the cards in multiple secure locations, never digitally photograph or type them. This seed phrase allows you to recover your entire wallet if your device is lost, stolen, or damaged. Treat it with the same security you would physical cash or important documents.

Add an additional layer of security by setting up a PIN code. The Trezor device will display a randomized number matrix to prevent keyloggers from capturing your input. Choose a PIN that's memorable but difficult for others to guess. The device will automatically wipe itself after multiple incorrect PIN attempts, protecting your funds from physical theft. This PIN is required every time you connect your device, ensuring that even if someone gains physical access to your Trezor, they cannot access your cryptocurrencies without the PIN.
