Introduction and preparation
Before you connect your Trezor device, make sure you are in a secure environment free from distractions. Locate the original box, the USB cable included with your device, and a separate pen and paper for writing your recovery seed. Remember the keyword for this guide: Trezor.io/start. The steps below are designed so anyone new to hardware wallets can complete the setup confidently.
Step 1 — Check the package and device
Verify tamper seals and packaging. Open the box carefully and confirm the device's holographic/tamper evidence (if present) is intact and that the unit matches the model you purchased. Never use a device showing signs of tampering.
Find the card that contains information about recovery seed storage and any included accessories. Do not connect the device to a computer until you are ready to follow the on-screen instructions.
Step 2 — Connect and visit Trezor.io/start
Use the official cable to connect the device to your computer or mobile adapter. Open a browser and navigate to the exact address https://trezor.io/start. Confirm the page's certificate and URL match exactly — this avoids phishing attempts. The official start page will guide you to the Trezor Suite or compatible software for initialization.
Step 3 — Install Trezor Suite or use recommended wallets
Trezor Suite is the official desktop and web interface for managing your device. Choose the Suite download for your operating system from the start page. If you prefer browser-based or third-party wallets, ensure they are officially supported and up-to-date. Do not install software from unverified sources.
Step 4 — Firmware checks and updates
When you first connect, the Suite will check your device's firmware version. If an update is available, the Suite will offer a secure update process. Always follow the update flow in the official Suite or the recommended interface — firmware updates often include security patches and important compatibility fixes.
Step 5 — Creating and securing your recovery seed
The recovery seed is the most critical piece of information for backing up your crypto. Trezor will generate a random recovery seed on the device screen — never on a connected computer. Write the seed clearly on the provided recovery card or another durable medium. Store it physically in a secure location (or multiple secure locations). Never photograph the seed or save it digitally.
Step 6 — PIN setup and passphrase (optional)
Set a PIN code on your Trezor to protect the device if stolen. Choose a PIN that is memorable to you but hard to guess. Optionally, enable a BIP39 passphrase for an additional hidden wallet — treat the passphrase as a second recovery secret. If you use a passphrase, never store it with the recovery seed.
Step 7 — Adding accounts and receiving funds
After initialization, add cryptocurrency accounts via Trezor Suite or supported third-party wallets. Generate receive addresses on the device whenever possible and verify each address on the Trezor screen before sharing it. Always confirm the address on the device display to avoid address substitution attacks.
Troubleshooting and best practices
If the Suite does not detect your device, try a different USB port or cable and confirm your operating system recognizes USB devices. Rebooting the computer can help. If firmware update fails, follow the recovery instructions published on the official start page. Never accept support from unknown third parties who ask for your seed or PIN.
Security reminders
Keep the following security reminders in mind: never share your recovery seed or PIN; always verify the URL trezor.io/start before installing software; use a tamper-evident envelope or safe deposit box for long-term seed storage; consider using metal seed storage for fire and water resistance. Use two-factor authentication where available for related accounts but understand 2FA is not a substitute for hardware backup.
When to contact official support
If you encounter unexpected behavior, suspicious firmware messages, or you suspect tampering, contact official Trezor support through the contact methods listed on the official site. Provide no sensitive information such as seed words or PINs when contacting support; official support will never ask for them.
For authoritative step-by-step guidance, always return to the official starting page at Trezor.io/start and follow the latest instructions provided by the Trezor team. This document is a general guide and not a substitute for the manufacturer’s up-to-date procedures.
