Trezor.io/Start – Your Complete Step-by-Step Guide

Step 1: Unbox Your Trezor Device

1. Open the official Trezor packaging carefully.
2. Verify the holographic seal is intact and matches Trezor’s design (silver with green pattern).
3. Inside, you should find:
   • Trezor Model One or Model T
   • USB-C cable (Model T) or Micro-USB (Model One)
   • Recovery seed cards (2x)
   • Getting Started guide
   • Trezor stickers

Step 2: Visit the Official Site

1. Open your web browser (Chrome, Firefox, or Edge recommended).
2. Type exactly: https://trezor.io/start
3. Bookmark this page for future reference.
4. Never click links from emails, social media, or search results.

Step 3: Install Trezor Bridge (Optional for Model T)

1. Trezor Model T works directly in modern browsers via WebUSB.
2. Trezor Model One requires Trezor Bridge for full functionality.
3. Click “Install Trezor Bridge” on trezor.io/start.
4. Download the correct version:
   • Windows: .exe
   • macOS: .dmg
   • Linux: .AppImage or .deb
5. Run the installer and follow on-screen instructions.

Step 4: Connect Your Trezor Device

1. Plug the USB cable into your computer and Trezor.
2. For Model T: Confirm “Allow connection” on the touchscreen.
3. For Model One: The green LED should light up.
4. Return to trezor.io/start in your browser.
5. Click “Continue” when your device is detected.

Step 5: Install Official Firmware

1. Your new Trezor has no firmware pre-installed for security.
2. On trezor.io/start, click “Install Firmware”.
3. Confirm the action on your Trezor device:
   • Model T: Tap “Continue” on screen
   • Model One: Press both buttons when prompted
4. Wait 1–2 minutes for download and verification.
5. Trezor will reboot automatically.

Step 6: Create a New Wallet

1. After reboot, click “Create new wallet” on trezor.io/start.
2. Check the box: “I understand recovery seed is important”
3. Click “Continue”.

Step 7: Backup Your Recovery Seed

1. Your Trezor will now display 12 or 24 words (depending on model).
2. Take the recovery card from the box.
3. Write down the words in exact order using a pen.
4. Never take a photo or store digitally.
5. Double-check every word for spelling and order.
6. Store in a safe, fireproof location (not with the device).

Step 8: Confirm Your Backup

1. Trezor will ask you to re-enter random words from your seed.
2. Enter them using the device interface:
   • Model T: Use touchscreen
   • Model One: Use computer + device buttons
3. If all words match, setup is complete.

Step 9: Set a PIN (Model One & T)

1. Click “Set PIN” in the browser.
2. Look at your Trezor screen — it shows a 3x3 grid of numbers.
3. Enter a strong 4–9 digit PIN on your computer (not device).
4. The numbers on screen shuffle each time for security.
5. Confirm the same PIN again.

Step 10: Name Your Device & Enable Passphrase (Optional)

1. Give your Trezor a name (e.g., “Main Wallet”).
2. Enable Passphrase for advanced security (creates hidden wallets).
3. If enabled, remember your passphrase — it’s not on the seed.

Final Step: Install Trezor Suite

1. Go to https://suite.trezor.io
2. Download Trezor Suite for your OS.
3. Open the app and connect your Trezor.
4. Add accounts (Bitcoin, Ethereum, etc.).
5. Send a test transaction with a small amount.
