🗲 TREZOR /start

The journey to securing your crypto begins with the **Trezor Suite**—your dedicated desktop application. Downloading the Suite directly from this official `Trezor.io/start` page or the provided link ensures you avoid malicious software. Before opening the box, **always perform a physical security check**: verify the packaging integrity, check for tamper seals, and ensure no components appear opened or used. If anything looks suspicious, contact support immediately. Once satisfied, download and install Trezor Suite for your operating system. This software acts as the secure, air-gapped interface between your computer and the private keys stored on your Trezor device. **Never use a web wallet or third-party application** for initial setup.

The Trezor Suite is mandatory because it provides the dedicated security environment for key operations, ensuring maximum protection against phishing and keyloggers.

Connect your Trezor device to your computer using the supplied cable. The Trezor Suite will immediately detect the device. For brand new devices, the Suite will guide you through the process of installing the latest official Trezor firmware. **This step is crucial**: new devices do not ship with pre-installed firmware. This mechanism guarantees that you are the first and only person to load the trusted software onto your hardware. Verify the firmware hash shown on your computer screen against the hash displayed on your Trezor device screen, if applicable. **Only install firmware approved and presented by the official Trezor Suite application.** Refuse any request to manually install files or use non-Suite tools.

The Trezor device will reboot after firmware installation. This is normal and prepares the device for the next, most critical step: generating your recovery seed.

Your **Recovery Seed** (24 words for Model T, 12-24 for Model One) is the single most important component of your security. It is the master backup that can restore your entire wallet and all your funds if your physical Trezor device is lost, stolen, or destroyed. The Trezor Suite will display the words one by one directly on the **Trezor device screen**—never on your computer screen. You must **write these words down meticulously** on the provided recovery seed cards, in the correct order.

• **Do NOT** take a picture, store it digitally, or type it into your computer.
• **Do NOT** laminate the card; store it in a secure, fireproof, and waterproof location.
• **TEST** your written seed immediately after creation using the 'Check backup' feature within Trezor Suite.

Completing this step successfully means your funds are secure and you hold the key to their recovery, which is the definition of true self-custody. Neglecting this step is the single biggest mistake a new user can make.

The final step in the primary setup is establishing a **Device PIN**. This PIN is required every time you connect and want to use your Trezor. It protects against casual theft—if someone briefly steals your device, they cannot access your funds without the PIN. The Trezor Suite uses an innovative, randomized PIN entry mechanism: the numbers on the computer screen are shuffled, and you enter the corresponding location of the numbers on the physical Trezor device screen. **Use a strong, unique PIN** (ideally 8-9 digits). The Trezor is designed to slow down brute-force attacks significantly, but a strong PIN remains your frontline defense.

Once the PIN is set, your Trezor is initialized, configured, and ready for use. You will now be taken to the Trezor Suite dashboard, where you can safely send, receive, and manage your portfolio with unparalleled security. Welcome to the future of digital asset control.
