Welcome to the official **Trezor** guide for **starting up your device**. We provide the most secure, step-by-step instructions for the **Trezor Model T** and other models. Master the use of **Trezor Suite** to achieve unbreakable **crypto security** and full control over your **crypto assets**. Your journey to self-custody begins here, at **Trezor.io/Start**.
Crucial **Seed Phrase** StepsThe foundation of your **Trezor wallet setup** is the **Trezor Suite** desktop application. **ALWAYS** download this software directly from the official **Trezor.io/Start** page to guarantee maximum **crypto security** and prevent phishing. The **Trezor Suite** serves as your primary interface for managing all your **crypto assets**. Once downloaded, launch the application and connect your **Trezor device** (Trezor Model T, Trezor One, etc.) using the provided USB cable. The **Trezor Suite** will immediately detect your **hardware wallet** and guide you through the initial firmware installation. This first interaction verifies the authenticity of your **Trezor device**, which is paramount for secure **starting up your device** and subsequent **crypto management**.
Security Check: Never use a web-based **Trezor wallet setup** link provided by an unsolicited email. Use only the **Trezor Suite** or the official **Trezor.io/Start** domain.
If your **Trezor device** is brand new, the **Trezor Suite** will prompt you to install the latest firmware. This process is automatic and essential for optimal performance and **crypto security**. The firmware is installed directly onto your **hardware wallet**. Once complete, the **Trezor Suite** will give you two options: "Create new **Trezor wallet**" or "Recover wallet." For first-time users, select "Create new **Trezor wallet**." This officially begins your secure **starting up your device** procedure. The firmware ensures the device operates correctly, isolating your private keys from the connected computer, which is a fundamental tenet of **hardware wallet** security. Always ensure the device screen matches the prompts in the **Trezor Suite**.
Model T Feature: The **Trezor Model T** allows you to input your PIN and **Seed Phrase** directly on its touchscreen, offering an unparalleled level of **crypto security**.
The **recovery seed** (your 12, 18, or 24-word **seed phrase**) is the master key to your **crypto assets**.
The **Trezor device** will display this sequence of words on its screen. You **MUST** copy this **seed phrase** meticulously onto the dedicated **Trezor** recovery card provided in the box. This phrase is the single, non-negotiable backup that allows you to restore your **Trezor wallet** and all associated **crypto assets** should your **hardware wallet** be lost, stolen, or destroyed. The private keys never leave the device, but the **seed phrase** is the decentralized recovery tool. After writing it down, the **Trezor device** will prompt you to confirm a few words for verification.
⚠️ **ABSOLUTE SECURITY MANDATE**
The final layer of local **crypto security** is setting your **PIN protection**. The **Trezor Suite** will display a scrambled number pad, and your **Trezor device** will show the actual positions of the numbers. You use the computer mouse to click the corresponding position on the scrambled pad, entering the PIN directly on the device screen (or touchscreen for **Trezor Model T**). This method defeats keyloggers and screen recording malware, providing a highly **reliable setup** for accessing your **hardware wallet**. Choose a PIN of 6 to 9 digits for optimal **PIN protection**.
With your **Trezor wallet setup** complete, you can now use **Trezor Suite** to manage your **crypto assets**. Add accounts for various cryptocurrencies (Bitcoin, Ethereum, etc.). To receive funds, click 'Receive' and verify the address directly on your **Trezor device** screen before sharing it—this prevents address substitution attacks. When sending funds, the transaction details (address, amount, fee) must be physically confirmed on the **hardware wallet** itself. This confirmation loop is the genius of **Trezor's crypto security**, ensuring all critical actions are verified in the isolated environment of the **Trezor device**. This completes the secure **starting up your device** process.
