• Secure Environment: A private, trusted location to perform the setup without interruptions or prying eyes.

Step-by-Step Setup Guide for Trezor.io/Start

Follow these steps to securely initialize your Trezor hardware wallet. The process typically takes 15–20 minutes and integrates seamlessly with Trezor Suite, the official desktop and web application for managing your crypto assets.

Step 1: Unbox and Verify Your Trezor Device

1. Inspect the Packaging: Upon receiving your Trezor, check for intact holographic security seals and ensure the box shows no signs of tampering. If anything looks suspicious, contact Trezor Support immediately via https://trezor.io/support/.
2. Check Contents: Confirm the box contains:
   • Trezor hardware wallet
   • USB cable
   • Recovery seed card(s)
   • User manual and stickers
3. Avoid Pre-Configured Devices: A genuine Trezor device arrives without pre-installed firmware or a pre-set recovery seed. If your device prompts you to enter a pre-existing seed, it may be compromised—stop and contact support.

Step 2: Visit Trezor.io/Start

1. Access the Official Portal: Open your browser and navigate to https://trezor.io/start. This is the only trusted portal for initializing your Trezor device. Beware of phishing sites with similar URLs—double-check the domain.
2. Select Your Device: Choose your Trezor model (One, Model T, Safe 3, or Safe 5) to access tailored instructions.
3. Download Trezor Suite (Optional): For the best experience, download the Trezor Suite desktop app from https://trezor.io or click “Continue in browser” to use the web app. Verify the PGP signature of the download for added security.

Step 3: Install Trezor Bridge

1. Download Trezor Bridge: Trezor Bridge is a lightweight software that enables communication between your Trezor device and your computer. Download it from the official Trezor website during the setup process.
2. Install the Software: Follow the on-screen instructions to install Trezor Bridge on your Windows, macOS, or Linux system.
3. Troubleshooting: If your device isn’t recognized, ensure Trezor Bridge is running and try a different USB port or cable.

Step 4: Connect Your Trezor Device

1. Plug in Your Trezor: Connect your Trezor to your computer using the provided USB cable. The device should power on and display a welcome message.
2. Verify Device Detection: Trezor Suite or the web app will detect your device. If prompted, install the latest firmware to ensure optimal security and functionality. Follow the on-screen instructions to complete the firmware update.

Step 5: Set Up a Secure PIN

1. Create a PIN: Trezor will prompt you to set a PIN (4–9 digits for Trezor One, up to 50 characters for Model T/Safe series). The PIN prevents unauthorized access to your device.
2. Randomized Keypad: For Trezor One, the keypad layout is randomized on your computer screen to prevent keylogging. For Model T/Safe series, enter the PIN directly on the device’s touchscreen or buttons to avoid exposing it to your computer.
3. Confirm the PIN: Re-enter the PIN to verify. Store it securely in your memory or a safe location—never digitally.

Step 6: Generate and Back Up Your Recovery Seed

1. Generate the Recovery Seed: Your Trezor will generate a recovery seed (12, 20, or 24 words, depending on the model). This seed is your master key to recover your wallet if your device is lost or damaged.
   • Trezor One: Generates a 24-word seed by default for enhanced security during recovery on a host computer.
   • Model T/Safe 3: Generates a 12-word seed (128 bits of entropy), sufficient for most users.
   • Safe 5: Uses a 20-word SLIP39 seed for advanced multi-share backup compatibility.
2. Write Down the Seed: Use the provided recovery seed card to handwrittenly record the words in the exact order displayed. Never store the seed digitally (e.g., on your phone, computer, or cloud).
3. Secure Storage: Store the seed card in a safe, private location, such as a fireproof safe or Trezor Keep Metal, a stainless steel backup solution designed to withstand fire, water, and physical damage.
4. Verify the Seed: Trezor Suite will ask you to confirm a few words from your seed to ensure accurate backup. For Trezor Model T/Safe series, this is done on-device for added security.

Step 7: Explore Advanced Features (Optional)

1. Passphrase Protection: Add an extra layer of security by enabling a passphrase, which creates hidden wallets. A passphrase can be any word or sentence up to 50 characters and must be stored separately from your seed. Be warned: losing your passphrase means losing access to the associated funds.
2. Shamir Backup (Model T/Safe 5): This feature splits your recovery seed into multiple shares (e.g., 20-word SLIP39 shares), requiring a threshold to reconstruct the wallet. It’s ideal for advanced users seeking enhanced security.
3. Custom Seed Length (Advanced): While Trezor One defaults to 24 words and Model T/Safe 3 to 12 words, you can generate a 24-word seed on Model T/Safe 3 using the trezorctl command-line tool or via https://connect.trezor.io/9/#/. This requires technical expertise and is not available directly in Trezor Suite.

Step 8: Start Managing Your Crypto

1. Access Trezor Suite: Once set up, use Trezor Suite to send, receive, and manage your cryptocurrencies. The app supports Bitcoin, Ethereum, and thousands of altcoins.
2. Verify Transactions: Always confirm transactions on your Trezor’s trusted display to ensure they match your intent, protecting against man-in-the-middle attacks.
3. Regular Backups: Periodically check your recovery seed and passphrase (if used) to ensure they are safe and legible.

Understanding Recovery Seed Lengths: 12, 20, or 24 Words?

Trezor devices generate recovery seeds of different lengths based on the model and backup standard:

• 12-Word Seed (BIP-39): Used by Trezor Model T and Safe 3, providing 128 bits of entropy. This is secure enough for most users, as brute-forcing 128 bits is computationally infeasible, even with quantum computers.
• 20-Word Seed (SLIP-39): Default for Trezor Safe 5, optimized for Shamir Backup. The wordlist is designed for easy recall, with a stronger checksum (last three words) and fewer keystrokes on T9 keyboards. It’s less compatible with other wallets but offers advanced multi-share recovery.
• 24-Word Seed (BIP-39): Default for Trezor One to enhance security during host computer recovery. It provides 256 bits of entropy, though the practical security gain over 12 words is minimal for most users.

Can You Use a 24-Word Seed on Model T/Safe 3?Yes, you can import or generate a 24-word seed using advanced methods (e.g., trezorctl or connect.trezor.io). However, Trezor recommends sticking with the default 12-word seed for simplicity, as it offers sufficient security.

Security Considerations:

• A 12-word seed is secure for direct device recovery but less so if entered on a host computer, hence Trezor One’s 24-word default.
• SLIP-39 (20 words) is less widely supported but ideal for multi-share backups. If compatibility with other wallets (e.g., Ledger) is a priority, use a 12/24-word BIP-39 seed.

Common Issues and Fixes

1. Device Not Recognized: Ensure Trezor Bridge is installed and running. Try a different USB port or cable.
2. Invalid Seed Phrase: Double-check the order and spelling of your seed words using the BIP-39 wordlist (https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt). Trezor Suite may prompt you to enter words in a specific order for verification.
3. Same Word in Seed: For SLIP-39 (20 words), repeated words are normal due to the wordlist design. For BIP-39 (12/24 words), this is unlikely but possible. If concerned, reset the device and generate a new seed.
4. Firmware Update Failure: Restart Trezor Suite, reconnect your device, and ensure a stable internet connection.
5. Difficulty Entering Words: For SLIP-39 seeds, words like “roaster” may not be recognized if mistaken for BIP-39. Reset and ensure you’re using the correct wordlist.

If issues persist, contact Trezor Support at https://trezor.io/support/. Never share your recovery seed with anyone, including support staff.

Best Practices for Security

• Store Seed Offline: Use Trezor Keep Metal for durable, tamper-evident storage. Avoid digital storage to prevent hacking.
• Use a Passphrase: Add a passphrase for hidden wallets, but store it separately and never lose it.
• Verify Authenticity: Always purchase Trezor devices from the official website or authorized resellers like Amazon’s Trezor Company store.
• Beware of Phishing: Only use trezor.io and connect.trezor.io for setup and management. Verify URLs and contact support for suspicious sites.
