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

Step 1: Verify Your Device

Before starting, ensure your Trezor device is authentic and untampered:

  • Check the packaging for tamper-evident stickers and holograms. Any signs of damage or tampering should prompt you to contact Trezor support immediately via https://trezor.io/support/.
  • Purchase Trezor devices only from official sources (e.g., Trezor’s website or authorized resellers like Amazon’s Trezor Company store) to avoid counterfeit devices.

Step 2: Visit Trezor.io/Start

  1. Open a secure web browser and navigate to Trezor.io/start. This is the official onboarding portal provided by SatoshiLabs.
  2. Avoid third-party websites or browser extensions to minimize the risk of phishing scams. Bookmark Trezor.io/start for future use.
  3. The portal will detect your operating system (Windows, macOS, Linux, or mobile) and prompt you to download Trezor Suite, the official companion app for managing your wallet.

Step 3: Download and Install Trezor Suite

  1. Click “Download for Desktop” or “Download for Mobile” on Trezor.io/start. Trezor Suite is available for:
  • Windows
  • macOS
  • Linux
  • iOS and Android (Trezor Suite Lite)
  1. Install the app following your system’s instructions. For desktop users, ensure you download only from Trezor.io/start or official app stores to avoid malicious software.
  2. Optionally, you can use the web version of Trezor Suite by selecting “Continue in browser,” but the desktop app is recommended for the best experience.

Step 4: Connect Your Trezor Device

  1. Use the USB cable provided with your Trezor device to connect it to your computer or mobile device.
  2. Launch Trezor Suite. The app will detect your device and guide you through the initialization process.
  3. If the device is not recognized, ensure Trezor Bridge (a communication tool between your device and computer) is installed. Trezor.io/start provides a link to download Trezor Bridge if needed.

Step 5: Install Firmware

  1. New Trezor devices come without firmware installed for security reasons. Trezor Suite will prompt you to install the latest firmware.
  2. Follow the on-screen instructions to complete the firmware installation. This step ensures your device has the latest security features and compatibility updates.
  3. Keep your firmware updated regularly via Trezor Suite to maintain optimal security.

Step 6: Create a New Wallet or Recover an Existing One

Trezor Suite offers two options:

  • Create a New Wallet: Recommended for new users or those setting up a fresh wallet.
  • Recover Wallet: For users with an existing recovery seed from a previous Trezor or compatible wallet.

Creating a New Wallet

  1. Select “Create a new wallet” in Trezor Suite.
  2. Your Trezor device will generate a recovery seed (a series of words). The number of words depends on your device and settings:
  • Trezor Model One: 24 words by default (BIP39 standard).
  • Trezor Model T and Safe 3: 12 words by default (BIP39), with an option for 20-word SLIP39 (Shamir Backup).
  • Custom Seed Length: Advanced users can use the trezorctl command-line tool to generate a 24-word seed on Model T or Safe 3, but this is not available directly in Trezor Suite for simplicity.
  1. Write down the recovery seed on the provided recovery card or a secure medium like the Trezor Keep Metal (aerospace-grade stainless steel backup solution). Never store the seed digitally (e.g., on your computer, phone, or cloud).
  2. Trezor Suite will prompt you to confirm specific words from your seed to verify you’ve recorded it correctly. This step is crucial for ensuring you can recover your wallet if the device is lost or damaged.

Recovering an Existing Wallet

  1. Select “Recover wallet” in Trezor Suite.
  2. Enter your recovery seed (12, 18, or 24 words) in the correct order. For Trezor Model One, you may need to enter the seed on your computer, but the process includes security measures like scrambled word order to prevent keylogger attacks.
  3. For Trezor Model T and Safe 3, enter the seed directly on the device’s touchscreen or keypad for enhanced security.
  4. Trezor supports BIP39 seeds (12, 18, or 24 words) and SLIP39 shares (20 words for Shamir Backup). Ensure your seed is compatible with your device.

Step 7: Set a PIN

  1. Trezor Suite will prompt you to set a PIN code to protect your device from unauthorized access.
  2. Choose a strong PIN (up to 9 digits for Model One, more complex for Model T and Safe 3). The PIN must be entered every time you connect your device.
  3. For Model T and Safe 3, enter the PIN on the device itself to avoid keylogger risks. Model One uses a scrambled keypad displayed on the device, which you interact with via your computer.

Step 8: Enable Cryptocurrency Accounts

  1. In Trezor Suite, add accounts for the cryptocurrencies you want to manage (e.g., Bitcoin, Ethereum, etc.).
  2. Click the “Receive” button to generate a public wallet address or QR code for each cryptocurrency. Use this address to send funds from exchanges or other wallets.
  3. Always verify the address on your Trezor device’s screen before confirming transactions to ensure security.

Step 9: Optional Security Features

  • Passphrase: Enable passphrase support in Trezor Suite’s Device settings to create hidden wallets. A passphrase is an additional word or phrase (up to 50 characters) that, when combined with your recovery seed, creates a unique wallet. Write down your passphrase and store it separately from your seed. Note:
  • Passphrases are case-sensitive and cannot be recovered if lost.
  • Entering a different passphrase creates a new hidden wallet, so accuracy is critical.
  • Shamir Backup (SLIP39): Available on Trezor Model T and Safe 3, this feature splits your recovery seed into multiple 20-word shares. For example, a 3-of-5 setup allows recovery with any three shares, enhancing redundancy and security. You can set this up via Trezor Suite’s Device settings.
  • Firmware Verification: Use Trezor Suite to verify your device’s authenticity and firmware integrity.

Security Best Practices

  1. Never Share Your Recovery Seed or Passphrase: Trezor staff will never ask for your seed or passphrase. Beware of phishing scams and fake support contacts.
  2. Store Backups Securely: Use offline storage like the Trezor Keep Metal or a fireproof safe. Avoid digital storage (e.g., photos, cloud, or password managers).
  3. Use Official Channels: Only download Trezor Suite from Trezor.io/start or official app stores. Verify URLs to avoid phishing sites.
  4. Regularly Update Firmware: Check for updates in Trezor Suite to ensure your device has the latest security patches.
  5. Test Your Backup: Perform a dry-run recovery (via Trezor Suite) to confirm your seed is correct without risking funds.
  6. Avoid Suspicious Links: If a website or message seems suspicious, contact Trezor support via https://trezor.io/support/.

Understanding Recovery Seeds and Backup Options

BIP39 vs. SLIP39

  • BIP39 (12, 18, or 24 Words): The standard for most hardware wallets, including Trezor. Trezor Model One defaults to 24 words for added security during recovery on a computer. Trezor Model T and Safe 3 default to 12 words, as they allow on-device seed entry, reducing keylogger risks. BIP39 seeds are widely compatible with other wallets.
  • SLIP39 (20 Words): Trezor’s Shamir Backup splits the seed into multiple shares, requiring a threshold (e.g., 3 out of 5) to recover the wallet. This is ideal for advanced users seeking redundancy and enhanced security. SLIP39 is less widely supported but compatible with select software wallets like Rabby, Electrum, and BlueWallet.

Seed Length and Security

  • 12-Word Seeds: Provide 128 bits of entropy, considered secure enough against brute-force attacks, even with quantum computers. Trezor Model T and Safe 3 use 12 words by default for simplicity.
  • 24-Word Seeds: Offer 256 bits of entropy, doubling the security but requiring more effort to store and recover. Trezor Model One uses 24 words to mitigate risks during computer-based recovery.
  • 20-Word Seeds (SLIP39): Encode 128 bits of entropy but allow multi-share backups, balancing security and flexibility.

Common Seed Length Concerns

  • Trezor Model One and 24-Word Seeds: The default 24-word seed is designed to protect against keylogger attacks during recovery, as the words are entered in a scrambled order with dummy words. This makes brute-forcing the correct order nearly impossible.
  • Changing Seed Length: Advanced users can use trezorctl to generate a 24-word seed on Model T or Safe 3, but this is not supported directly in Trezor Suite to avoid complicating the user experience.
  • Compatibility: Trezor supports importing 12, 18, or 24-word BIP39 seeds from other wallets (e.g., Ledger). However, 20-word SLIP39 seeds are less compatible with non-Trezor wallets.

Troubleshooting Common Issues

  1. Device Not Recognized: Ensure Trezor Bridge is installed and your USB cable is functional. Try a different USB port or cable.
  2. Firmware Update Failure: Restart Trezor Suite and try again. Contact support if the issue persists.
  3. Invalid Seed: If your seed is rejected, verify the word order and spelling against the BIP39 word list (https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt). Ensure you’re entering the seed on the correct device model.
  4. 20-Word Seed Limitations: SLIP39 20-word seeds are less compatible with non-Trezor wallets. If you need broader compatibility, reset your device and create a BIP39 12 or 24-word seed.

Advanced Features and Tips

  • Coin Control: Available in Trezor Suite (version 25.7.2 and later), this feature lets you select specific UTXOs for Bitcoin transactions, optimizing privacy and fees.
  • Stellar (XLM) Support: Added in Trezor Suite 25.7.2, allowing you to manage XLM alongside other cryptocurrencies.
  • Passphrase Best Practices: Use a memorable phrase (e.g., 7+ words with spaces) for security and ease of entry. Avoid complex character strings, as they’re harder to input on devices like Model One or Safe 3.
  • Reset and Wipe: If you need to reset your device, use Trezor Suite’s Device settings or visit
