Introduction: Secure Start for Your Trezor

Starting your Trezor device correctly is the cornerstone of safe cryptocurrency management. Trezor hardware wallets, including the Model T and Safe 5, maintain your private keys offline, require physical button confirmation for transactions, and protect your assets from online threats.

With open-source firmware regularly updated and support for over 1800 cryptocurrencies, starting your device ensures you harness top-tier security and seamless asset control in 2025.

Step 1: Verify Device Authenticity

Inspect the Holographic Seal Examine the tamper-evident holographic seal on your device's packaging. If it's broken or suspicious, stop and contact Trezor support. This step prevents compromised devices from risk.
Unboxing Contents Confirm the box includes your Trezor device, USB cable, recovery seed cards, magnetic dock (Safe 5), quick-start guide, and official stickers for authenticity and smooth setup.

Step 2: Install and Update Firmware

When first powered, your Trezor device will not have firmware installed. Visit trezor.io/start and connect your device via USB. Use the official Trezor Suite app to install the latest firmware version, unlocking support for new coins, enhanced security, and improved device performance.

Firmware verification is always automatic on boot, guaranteeing no unauthorized code execution.

Step 3: Create and Secure Your Recovery Seed

Your device generates a 12 to 24-word recovery seed, the master key to your wallet. Write down the seed carefully on the supplied cards and store them offline in secure locations.

Do not store or photograph your seed phrase digitally. Anyone with this phrase can gain full control over your funds, so treat it like your most valuable secret.

Advanced users can enable Shamir Backup, splitting the seed into multiple shares for distributed recovery.

Step 4: Set a Strong PIN Code

Set up your device PIN to protect against unauthorized physical use. Your PIN is entered on a randomized keypad displayed on the device screen, preventing observation attacks.

PIN length ranges from 4 to 50 digits, offering flexible security tailored to your preference.

Step 5: Optional Passphrase Protection

Enable passphrase protection for an additional security layer. This acts as a 25th seed word generating hidden wallets out of sight, giving plausible deniability and added privacy to your holdings.
