Trézor.io/Start® — Starting Up Your Device

Before you begin

Unbox your Trézor® and find the essentials: the device, a USB cable, recovery seed card(s), and any stickers or documentation. Use a clean, private space and avoid public Wi‑Fi when initializing. Keep your phone or computer nearby — you will need to connect the device to start.trezor.io (or trezor.io/start), follow the on-screen instructions, and install official firmware.

What you will do (at a glance)

1. Plug the device into your computer or phone using the supplied cable.
2. Open your browser and navigate to trezor.io/start.
3. Install the recommended Trezor Suite app or use the web setup flow.
4. Follow the on-device instructions to install firmware and create a new wallet or recover an existing one.
5. Write down your recovery seed exactly on the provided card(s) and store it offline in a safe place.
6. Set a PIN to protect the device from unauthorized access.

Step-by-step: First power-up and initialization

1. Connect and verify

Use the official USB cable to connect your Trézor® to the computer or phone. The device screen will light up and display a welcome message plus a device model number. Confirm the model matches the packaging.

2. Open the official start page

Open your web browser and type trezor.io/start manually — avoid clicking random links. The site will guide you to download Trezor Suite or continue with the web interface. Choose the option that fits your preference.

3. Install firmware

If the device requires firmware, the official site will prompt a secure firmware installation. Let the process complete — do not unplug the device mid-update. The device screen shows verification phrases; compare them with the browser to ensure the connection is genuine.

4. Create or recover a wallet

Choose Create new to initialize a fresh wallet. The device will generate a recovery seed — usually 12, 18, or 24 words depending on your chosen settings. Write each word clearly, in order, on the recovery card supplied. Double-check spelling and order; this is the only way to recover assets if your device is lost or damaged.

5. Set up a PIN

Create a PIN code on the device. The PIN adds an extra layer of security: it encrypts access to the device and prevents unauthorized withdrawals even if someone has your hardware wallet physically.

Best practices for your recovery seed

• Never store the seed digitally (screenshots, cloud notes, email).
• Keep multiple physical copies in separate secure locations if possible.
• Consider fireproof, waterproof storage solutions for long-term protection.
• Do not tell anyone your seed. No legitimate support will ever ask for it.

Troubleshooting & common questions

My device won't power on. What do I do?

Try a different USB cable and port. Use a direct computer USB port rather than a hub. If it still fails, consult official support.

Should I update firmware immediately?

Yes. Firmware updates include security fixes and should be applied as prompted by the official start flow.

Can I recover my wallet on another device?

Yes. With your recovery seed you can restore funds onto another compatible hardware wallet. Keep that seed secure.

I found my recovery words written incorrectly — what now?

Do not attempt to guess. Safely wipe the device and re-initialize to generate a new, correct seed.

After setup: small steps that matter

Once your wallet is ready, send a small test transaction to confirm everything works before transferring larger amounts. Explore Trezor Suite to check addresses, manage multiple cryptocurrencies, and enable advanced features like passphrase protection if you need additional secrecy.
