Before you start — what you'll need

• Your Trezor device (Model T or One) fresh from the original packaging.
• A computer (Windows, macOS, or Linux) or supported mobile device and a USB cable.
• Time and a quiet, private place to write down your recovery seed — do not rush.
• A pen and the provided recovery card (or a secure offline method to store your seed).

Security reminder: Never share your recovery seed, enter it into websites, or store it digitally (photographs, cloud storage, text notes). The recovery seed is the single key to all funds controlled by the device.

Step-by-step setup (first-time)

1. Unbox & inspect. Verify the packaging seals and device integrity. Trezor devices ship with tamper-evident packaging — if something looks off, contact official support.
2. Connect your Trezor. Use the supplied USB cable to connect the device to your computer. For mobile setups, use an OTG adapter if needed.
3. Open Trezor Suite or go to the official Start page. In your browser, follow the official prompts (do not install random third-party apps). The device screen will guide you — confirm that the website address is correct and secure.
4. Create a new wallet. Choose Create new when prompted. The device will generate a random recovery seed (typically 12, 18 or 24 words depending on model/options).
5. Write down your recovery seed. Carefully write each word on the recovery card in order. Double-check spelling and order. Keep the card offline and stored securely.
6. Set a PIN on the device. Choose a PIN that you can remember but that isn't easily guessable. The PIN protects your device if it is lost or stolen. Trezor will not store this PIN anywhere.
7. Confirm seed backup on the device. The device will ask you to confirm several words from the seed. This ensures you recorded it correctly.
8. Finish setup and install apps if needed. Once complete, you can install companion apps and add cryptocurrency accounts inside Trezor Suite to view and manage assets.

If at any time you're unsure, pause. It's better to re-check than to move forward with uncertainty.

Restoring an existing wallet

If you already have a recovery seed from a previous device, choose Recover wallet during setup. You will be prompted to enter the exact words of your recovery seed in order. After restoration, the device will regenerate your accounts and balances — the funds are not stored on Trezor itself but on the blockchain.

Only restore your seed on a trusted, official device. Never type your seed into a website or app.

Daily use — receiving, sending, and managing assets

1. Receive funds: Generate a receiving address using Trezor Suite and verify it on the device screen before sharing it. Always confirm the address on the physical device display.
2. Send funds: Create a transaction in your wallet interface. When prompted, confirm amounts and destination addresses on your Trezor device. Physically approve the transaction — the device verifies the transaction details independently of your computer.
3. Install coin-specific apps: Some cryptocurrencies require additional apps or integrations. Follow official instructions and only use trusted integrations endorsed by Trezor.

Never approve transactions you do not recognize. If details differ between your screen and the device display, reject the transaction immediately.

Advanced security tips

• Passphrase (optional): For extra security you can enable a passphrase (a 25th word). Treat it like an additional password — if you forget it, funds protected by that passphrase are unrecoverable.
• Geographic redundancy: Store copies of your recovery seed in multiple secure physical locations (e.g., safety deposit box and a trusted relative) to guard against loss or disaster.
• Test your backup: Before transferring large amounts, test restoring a small balance or restoring the seed on a separate device to verify the backup is accurate.
• Keep software updated: Regularly update Trezor firmware and Trezor Suite — official updates fix bugs and improve security.

FAQ — Common questions

Q: Can Trezor be hacked?
A: While no device is 100% immune, hardware wallets like Trezor isolate private keys offline, greatly reducing online attack vectors. Follow best practices: never expose your seed and keep firmware up to date.

Q: What if I lose my Trezor?
A: You can restore your wallet using your recovery seed on a new Trezor or compatible device. If you lose the recovery seed as well, funds cannot be recovered.

Q: Can I use Trezor with multiple computers?
A: Yes. Your device and seed are independent of the computer. Use Trezor Suite or supported wallet interfaces on any trusted machine and connect your device when needed.

Need help or suspect an issue?

If anything seems wrong with your device, packaging, or setup process, stop and contact official support. For guidance, always use official Trezor resources and authorized channels. Keep proof of purchase and serial numbers handy when contacting support.

Never follow instructions from unknown sources that ask for your recovery seed or PIN.
