Step-by-step setup (detailed)
Open a browser and go to trezor.io/start. Verify the URL and the TLS padlock. The page will show links to download Trezor Suite and provide web-based setup instructions.
Download and install Trezor Suite if prompted. Trezor Suite is the official management interface for firmware updates, account setup, and operations. Install the version matching your operating system.
Connect your Trezor to your computer using the included USB cable. The device screen will light up with a welcome message. Confirm the model and serial number if prompted by the Suite.
Verify firmware — the Suite will check if a firmware update is needed. If so, follow the instructions. Firmware is cryptographically signed by Trezor; the Suite verifies signatures to protect you from tampered firmware.
Create a new wallet — choose to create a new wallet when instructed. The Trezor device will generate a recovery seed (12, 18, or 24 words) and display it on the device screen only. IMPORTANT: write every word down in order on paper or the included recovery card. Do not take photos, screenshots, or store the seed digitally.
Confirm your seed by entering a few words when prompted. This step ensures your backup is accurate and recoverable.
Set a PIN code to protect access to the device. The Trezor shows a randomized keypad layout on the device, making PIN entry resilient to screen logging or keyloggers on the connected computer.
Optional: enable passphrase (hidden wallet) for additional layering of security. A passphrase creates a separate hidden wallet linked to your seed; losing the passphrase means losing access to that hidden wallet.
Add cryptocurrency accounts inside Trezor Suite to manage Bitcoin, Ethereum, and supported altcoins. For each account, always verify addresses on the physical device screen before sending funds.
Recovery strategy
The recovery seed is the ultimate backup of your private keys. Store it offline in a safe location — preferably in multiple copies stored separately (e.g., a safe deposit box, a home safe, or a metal backup). For long-term storage, consider durable metal backups that resist fire, water, and degradation. Plan for inheritance or emergency access: document in a secure way who should gain access if something happens to you, without revealing the seed itself.
Security best practices
Never enter your seed into a computer or online service. Avoid storing backups in cloud storage, photos, or notes apps. Always confirm transaction details on the Trezor device screen rather than relying solely on your computer display; this prevents malware from altering addresses or amounts. Keep your firmware updated via Trezor Suite and only download updates from official channels.
Using passphrases and hidden wallets
Passphrases let you create additional, concealed wallets from the same seed. They offer strong privacy and security benefits but add complexity: if you forget a passphrase, funds in that hidden wallet are unrecoverable. Use passphrases only if you understand the risks and have secure methods to remember or store them.
Integrations & advanced use
Trezor can be used with third-party wallets and services that support hardware wallets. When using integrations, always validate addresses on your Trezor screen. Advanced users may set up multisignature configurations or use Trezor in combination with other custody tools for institutional-grade security.
Troubleshooting common issues
If your Trezor isn't detected, try a different USB port or cable (some cables are power-only and will not transmit data). Restart Trezor Suite and the computer. If firmware update fails, reattempt using the official instructions on trezor.io/start. For hardware failure or suspicious behavior, contact official Trezor support — do not publish your seed or PIN in support requests.
Final notes & responsibilities
Hardware wallets like Trezor put you in full control of your crypto. That control brings personal responsibility: protect your recovery seed, follow security guidance, and treat your device as a high-value asset. If you plan to hold significant funds long-term, consider a documented custody plan and periodic checks to ensure your recovery method remains intact as your life circumstances change.
