Trezor.io/Start® — The Official 2026 Guide to Setting Up Your Device

Securing your digital wealth begins at Trezor.io/Start. As the pioneer of hardware wallets, Trezor provides a transparent, open-source environment designed to give you 100% ownership of your private keys. Whether you’ve chosen the high-performance Trezor Safe 5, the security-focused Safe 3, or the classic Model One, this guide ensures your setup is flawless and your assets remain impenetrable.

Step 1: Secure the Official Software

The most critical moment in your security journey is the very beginning. To prevent phishing and malicious "clones," only download software from the source.

  • Official Link: Visit Trezor.io/Start to download the Trezor Suite desktop application.
  • Platform Support: Available for Windows, macOS, and Linux. For 2026, ensure your OS is fully patched to support the latest cryptographic drivers.
  • Verification: Upon installation, Trezor Suite will perform a Secure Element Authenticity Check (for Safe 3/5 models) to confirm the device is genuine and has not been tampered with.

Step 2: Initialize & Install Firmware

Your Trezor arrives without firmware to ensure that you—the user—are the only one to ever install the "brain" of the device.

  1. Connect: Use the provided USB-C or Micro-USB cable to plug your device into your computer.
  2. Install Firmware: Follow the prompts in Trezor Suite to install the latest firmware. You can choose the Standard Firmware (for all assets) or Bitcoin-Only Firmware for an even smaller attack surface if you only hold BTC.
  3. Restart: The device will automatically reboot once the installation is successful.

Step 3: The Wallet Backup (Your Master Key)

Trezor has updated its terminology for 2026, moving from "Recovery Seed" to "Wallet Backup." This is the single most important step in the process.

Choose Your Backup Type:

  • Standard Backup (12 or 24 words): Available on all models. This is a single list of words that recovers your entire wallet.
  • Shamir Backup (SLIP39): Available on the Trezor Safe 5 and Model T. This allows you to split your recovery phrase into multiple "shares" (e.g., a 2-of-3 setup). If you lose one share, you can still recover your funds with the remaining two.

CRITICAL: Write your words on the provided physical cards. Never take a photo, never save them in a password manager, and never type them into a website. If you lose your Trezor, these words are the only way to get your money back.

Step 4: PIN & Passphrase Security

Physical security is just as important as digital security.

  • Set a PIN: Create a unique 4- to 50-digit PIN. Trezor uses a randomized grid on the device screen, so even if your computer has a keylogger, your PIN remains secret.
  • Optional Passphrase (The "25th Word"): For advanced users, enable the Passphrase feature. This creates a "hidden wallet." Even if someone steals your 24 words, they cannot access the hidden wallet without this final, custom phrase.

Step 5: Managing Your Portfolio

Once your device is "Ready," you can enter the Trezor Suite dashboard to manage your coins.

  • Add Accounts: Click the "+" icon in the sidebar to enable Bitcoin, Ethereum, Solana, and thousands of other tokens.
  • Verify Addresses: When receiving funds, always compare the address on your Trezor device screen with the one on your computer. If they match, it is safe to proceed.
  • Buy/Sell/Swap: Use the integrated Invity exchange within Trezor Suite to trade assets directly from your cold storage, keeping your private keys offline throughout the entire trade.

Why Choose Trezor in 2026?
