This guide will walk you through the entire process, from unboxing your Trezor device to securely managing your cryptocurrencies.

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

Step 1: Verify Your Trezor Device

Before starting, ensure your Trezor hardware wallet’s packaging is intact and untampered. Trezor devices come in sealed boxes with tamper-evident stickers. If you notice any damage or missing seals, contact Trezor’s official support immediately through trezor.io/support. This step is critical to confirm the device’s authenticity and protect against compromised hardware.

Check the Packaging: Look for the hologram and tamper-evident stickers.
Inspect the Device: Ensure no signs of physical tampering, such as scratches or loose components.
Purchase from Trusted Sources: Only buy from Trezor’s official website or authorized resellers to avoid counterfeit devices.

Step 2: Visit Trezor.io/start

Navigate to Trezor.io/start, the official onboarding portal. This page detects your operating system (Windows, macOS, Linux, or mobile) and prompts you to download the Trezor Suite software, the control center for managing your Trezor device and cryptocurrencies.

Download Trezor Suite:

Click “Download for Desktop” or “Download for Mobile” based on your device.
For desktop, choose the appropriate version for your operating system.
For mobile, download from official app stores (Google Play or Apple App Store).

Verify the Download: Trezor Suite should only be downloaded from trezor.io/start to avoid malicious software. Check the PGP signature if you’re technically inclined to ensure authenticity.
Install Trezor Suite: Follow your system’s installation instructions. For desktop, this involves running the installer and granting necessary permissions.

Step 3: Connect Your Trezor Device

Once Trezor Suite is installed, connect your Trezor device to your computer or mobile device using the provided USB cable (USB-C for Model T and newer models, USB-A for Model One).

Plug in the Device: Insert the USB cable into your Trezor and connect it to your computer or mobile device.
Launch Trezor Suite: Open the app or select “Continue in browser” for the web version (though the desktop app is recommended for the best experience).
Firmware Check: Trezor Suite will check your device’s firmware. If an update is required, follow the on-screen instructions to install the latest firmware. Keeping firmware updated is crucial for security and compatibility.

Step 4: Create or Recover a Wallet

Trezor Suite will prompt you to either create a new wallet or recover an existing one. For new users, select the “Create New Wallet” option.

Creating a New Wallet

Select Wallet Type:

Single Backup Wallet (BIP39): Generates a 12 or 24-word recovery seed, depending on the device (12 for Model T and Safe 3, 24 for Model One).
Shamir Backup Wallet (SLIP39): Available on Model T and newer models, this creates a 20-word seed with optional multi-share backups for added security.

Set a PIN:

Trezor will prompt you to create a PIN code (4–8 digits) to protect your device from unauthorized access.
Enter the PIN twice on your Trezor device (not on your computer for Model T and newer models) to confirm.
For Model One, you’ll enter the PIN using a randomized grid displayed on the device and clicked on your computer, enhancing security against keyloggers.

Generate Recovery Seed:

Trezor will display a series of words (12, 18, or 24 for BIP39; 20 for SLIP39) on the device’s screen.
Write down these words in the correct order on the provided recovery card or a secure medium like the Trezor Keep Metal.
Never store the seed digitally or share it with anyone. Keep it offline in a safe location.

Verify the Seed:

Trezor Suite will ask you to confirm specific words from your recovery seed to ensure you’ve recorded it correctly.
For Shamir Backup, you may need to verify multiple shares if you’ve chosen a multi-share setup.

Recovering an Existing Wallet

If you have a previous recovery seed (from a Trezor or another BIP39/SLIP39-compatible wallet), select “Recover Wallet”:

Enter the Seed:

For Model T and newer models, input the seed directly on the device’s touchscreen.
For Model One, enter the words using your computer, following the device’s scrambled input order to protect against keyloggers.

Set a New PIN: Assign a new PIN for the recovered wallet.
Verify Compatibility: Ensure the seed length (12, 18, 24, or 20 words) is supported by your Trezor model. Most hardware wallets support 12 or 24-word BIP39 seeds, but SLIP39 (20 words) has limited compatibility.

Step 5: Secure Your Backup

The recovery seed is the master key to your wallet. If your Trezor is lost, damaged, or reset, the seed is the only way to recover your funds. Follow these best practices:

Store Offline: Write the seed on the provided recovery card or a durable medium like the Trezor Keep Metal, designed to withstand fire and water.
Avoid Digital Storage: Never save the seed on a computer, phone, or cloud service, as these are vulnerable to hacking.
Use Shamir Backup (Optional): For Model T and newer models, Shamir Backup (SLIP39) allows you to split your seed into multiple 20-word shares. For example, a 3-of-5 setup requires any three shares to recover the wallet, providing redundancy and security.
Keep Shares Separate: Store Shamir Backup shares in different secure locations to prevent a single point of failure.

Step 6: Add Cryptocurrency Accounts

After setup, use Trezor Suite to add accounts for your cryptocurrencies:

Select Coins: Choose from supported cryptocurrencies like Bitcoin, Ethereum, or others.
Generate Addresses: Click “Receive” in Trezor Suite to generate a public wallet address or QR code. Use this to send crypto from exchanges or other wallets.
Verify Addresses: Always confirm the address on your Trezor device’s screen before sending funds to ensure it hasn’t been altered by malware.

Step 7: Enable Advanced Security Features

Trezor offers additional features to enhance security:

Passphrase: Add a custom passphrase (a “25th word” for BIP39) to create hidden wallets. Store the passphrase separately from the seed, preferably in a password manager or offline.
Multi-Share Backup (SLIP39): For advanced users, create multiple shares to distribute risk. For example, store shares in different locations, requiring a threshold (e.g., 3 out of 5) to recover the wallet.
Regular Firmware Updates: Check for updates in Trezor Suite to ensure your device remains secure against new threats.

Understanding Recovery Seed Options

Trezor supports two backup formats:

BIP39 (12 or 24 Words):
12 Words: Default for Trezor Model T and Safe 3 (128-bit entropy). Secure enough for most users, with 2^128 possible combinations, making brute-forcing infeasible.
24 Words: Default for Trezor Model One (256-bit entropy). Offers higher entropy, primarily due to the device’s recovery process requiring computer input, which could be vulnerable to keyloggers.
Compatibility: Widely supported across most hardware and software wallets.
SLIP39 (20 Words):
Shamir Backup: Available on Model T and newer models. Uses 20-word shares, with optional multi-share setups for redundancy.
Compatibility: Less widely supported (e.g., supported by Keystone, Rabby, Electrum, and BlueWallet, with more wallets adding support in 2024).
Unique Feature: The first four words (e.g., “academic/academic” for positions 3 and 4) are metadata, not random, ensuring checksum and group data.

Choosing Between 12, 20, or 24 Words

12 Words (BIP39): Sufficient for most users, offering 128-bit entropy, which is secure against brute-force attacks, even with quantum computers. Easier to manage and recover.
24 Words (BIP39): Offers 256-bit entropy, doubling the security margin. Required for Model One due to its recovery process. Can be generated on Model T via advanced commands (trezorctl) but not through Trezor Suite’s GUI.
20 Words (SLIP39): Ideal for users wanting multi-share backups. Less compatible with other wallets, so ensure you have a Trezor or compatible software wallet for recovery.

Note: Some users have reported generating 18-word seeds when using third-party wallets like Exodus with Trezor. This is not a standard Trezor setup and may indicate a configuration error or third-party software influence.

Security Best Practices

To maximize the security of your Trezor wallet:

Never Share Your Seed: No one, including Trezor support, will ever ask for your recovery seed. Beware of phishing scams claiming to be Trezor support.
Test Your Backup: Perform a dry-run recovery in Trezor Suite to verify your seed or shares are correct without risking funds.
Avoid Unofficial Websites: Only use trezor.io/start or official app stores for downloads. Sites like connect.trezor.io may be legitimate but should be verified with Trezor support.
Use a Passphrase: A passphrase adds an extra layer of security, creating a hidden wallet even if someone obtains your seed.
Check for Misspellings: When recovering, ensure seed words match the BIP39 wordlist (available at github.com/bitcoin/bips/blob/master/bip-0039/english.txt). Common misspellings can prevent recovery.

Advanced Features and Tips

Using Trezor with Third-Party Wallets: Trezor supports integration with wallets like Electrum, Rabby, and BlueWallet. Be cautious with third-party software, as it may not support SLIP39 or all Trezor features.
Generating a 24-Word Seed on Model T: For advanced users, use the trezorctl command-line tool to initialize a 24-word seed. This requires technical knowledge and is not supported in Trezor Suite’s GUI.
Shamir Backup Configuration: On Model T, create up to 16 shares with a custom threshold (e.g., 3-of-5). Test each share to ensure recoverability.
Crypto Management: Use Trezor Suite to track prices, send/receive crypto, and trade directly within the app for a seamless experience.

Troubleshooting Common Issues

Invalid Seed: If your seed is rejected, check for misspellings or incorrect order. Use the BIP39 wordlist to verify words.
Firmware Issues: If Trezor Suite prompts for a firmware update but fails, restart the app, reconnect the device, or try a different USB port.
20-Word Seed Compatibility: SLIP39 seeds are less widely supported. If you lose your Trezor, ensure you have a compatible wallet (e.g., Rabby or another Trezor) to recover funds.
Tampered Device Concerns: If your device generates an unexpected seed length (e.g., 18 words), verify the setup process and contact Trezor support to rule out tampering.
