The journey into secure self-custody begins with a single, critical step: the initial setup of your hardware wallet. For Trezor users, this launchpad is Trezor.io/start.

This guide provides the definitive, E-E-A-T-compliant walkthrough of the entire process, ensuring your first interaction with your new device is secure, informed, and flawless. We’ll cover everything from the crucial anti-tampering checks to creating your unshakeable backup.

Before you plug anything in, your Trustworthiness and security start with a physical check. Trezor.io/start guides you through the necessary steps to verify your device's authenticity.

The Security Checklist

• Check the Packaging: Inspect the box for any signs of tampering, tears, or prior opening. Genuine Trezor packaging is designed to show clear evidence of intrusion.

• Holographic Seal (Model T / Older Devices): If you have an older model, verify the holographic seal over the USB port. If it’s broken, scratched, or has residue, do not proceed. Contact Trezor support immediately.

• Secure Element Check (Newer Devices): Newer models like the Trezor Safe 3 perform a cryptographic Secure Element authenticity check during the software setup, confirming the device is genuine and unaltered by verifying its cryptographic signature.

The Golden Rule: If anything feels wrong, stop. A hardware wallet's security relies on its physical integrity.

The primary function of Trezor.io/start is to direct you to the official, verified source for the companion software: Trezor Suite.

Download and Installation

1. Navigate Safely: Always manually type Trezor.io/start into your browser's address bar. Do not click links from emails or unverified search results.

2. Download Trezor Suite: Trezor.io/start clearly prompts you to download the Trezor Suite desktop application. The desktop app is highly recommended as it provides the most secure and comprehensive Experience.

3. Install and Connect: Install the Trezor Suite app. Once opened, it will prompt you to connect your Trezor device using the USB cable provided in the box.

Your Trezor device ships blank, without operational firmware. This is a security feature, preventing pre-loaded malicious software.

• Guided Process: Trezor Suite (launched from the /start process) will detect the blank state and prompt you to Install Firmware.

• Verification: The Suite automatically downloads and cryptographically verifies the latest, official firmware directly onto the device, which you must confirm on the Trezor screen itself.

This is the most crucial step of the entire setup process. Your Recovery Seed (or wallet backup) is the sole master key to your crypto funds.

The Backup Protocol (Experience)

1. Create New Wallet: In Trezor Suite, select "Create new wallet." You will then choose your backup type (e.g., Standard Single-share Backup).

2. Display on Device: Your Trezor device's screen will display a series of 12, 18, 20, or 24 words (depending on the model and backup method). Crucially, these words are never shown on your computer screen.

3. Physical Recording: Use the provided recovery seed cards to physically write down the words in the exact order. Check your spelling twice.

4. Verification: The device will then prompt you to confirm a few of the words to ensure you have recorded them correctly.

5. Storage: Store this physical backup safely offline—in a fireproof safe, a secure location, or ideally, engraved in metal (such as Trezor Keep Metal). Never take a photo or store a digital copy.

Setting Your PIN

After the seed backup, you will be prompted to set a PIN.

• Device Entry: Enter your PIN directly on the Trezor device using the changing number pad layout shown on your computer screen (for Model One) or directly on the device touchscreen (for Model T/Safe 3). This protects against keyloggers.

• Minimum Length: Choose a strong PIN, recommended at least 4-8 digits.

With the firmware, backup, and PIN complete, you’ll be guided to the Trezor Suite Dashboard.

• Activate Coins: The Suite will ask you which cryptocurrencies you wish to enable and view in your portfolio (e.g., Bitcoin, Ethereum, Cardano). You can change this anytime.

• Access Suite: Click Access Suite to begin managing your crypto. You can now use the interface to securely Receive funds (always confirming the address on your device) and Send funds (always confirming the transaction details on your device).

By following the secure path laid out by Trezor.io/start, you have successfully transitioned from a risky exchange holder to a sovereign owner of your digital assets. For ongoing security best practices and advanced features like the Passphrase, consult the official documentation.
