Trezor.io/Start — Official Setup Guide

1. Inspect the packaging. A genuine Trezor arrives in tamper-evident packaging. Look for broken seals, tears, or strange glue spots.
2. Confirm the holographic label and product markings. If anything looks off, stop and contact the seller.
3. Find the quick-start leaflet and the device. Keep the box — it contains your serial number and support QR codes.

1. Go to trezor.io/start using a browser you trust. Bookmark it.
2. Follow the on-screen steps to download the official Trezor web/desktop app if needed (Trezor Suite).
3. Connect your Trezor to your computer using the supplied USB cable. The device screen should light up with a welcome message.
4. Do not accept random browser pop-ups asking for your recovery seed or to install unknown plugins.

Official firmware is signed and verified. If your device requires a firmware update, Trezor Suite will guide you through the process.

1. When prompted, confirm the firmware update on the device screen by physically pressing the buttons when asked.
2. Never install firmware from third-party sources. The device verifies signatures internally.

1. Choose "Create new" in Trezor Suite when asked. Your Trezor will generate a recovery seed — a human-readable list of words (usually 12, 18, or 24 words).
2. Write the words down in order on the provided recovery card. Use a single pen stroke per word; ensure legibility.
3. Never take photos of your seed, store it digitaly, or type it into a computer. Offline, air-gapped, or metal backups are best practice for high-value holdings.
4. Confirm the seed words on the device when prompted. This ensures the words were recorded correctly.

1. Set a strong numeric PIN on the Trezor device. The PIN prevents the device from being used even if it is physically stolen.
2. Optionally add a passphrase (advanced users): a passphrase acts as an additional 25th word — it is not stored on the device and must be memorized. Use a passphrase only if you understand the tradeoffs.
3. Give your device a label (e.g., "Home Trezor") in Trezor Suite to keep track of multiple devices.

After setup, you can receive funds using Trezor Suite or compatible wallets. Always verify addresses on the device screen before sending funds.

1. To receive: In the app, select the account, click "Receive" and verify the full address on your device screen. The receiving address displayed in the app must match the device display exactly.
2. To send: Create a transaction in the app, then confirm transaction details (amount and destination) on the device before approving. Trezor shows transaction details to avoid phishing.
3. Use the built-in exchange integrations or connect to trusted services if you need swaps. Confirm all on-device prompts.

1. Store your written seed in at least two geographically separated secure locations.
2. Use a metal backup for extreme safety. Test restoring from a backup on a spare device to ensure readability and accuracy.
3. Do not store your recovery seed in cloud storage, photos, email drafts, or on your phone.
4. If your device is lost or stolen, use the seed to restore funds to a new Trezor. If you used a passphrase, you must remember or have stored that passphrase securely.

Passphrases unlock hidden wallets derived from the same seed. They offer plausible deniability but come with responsibility:

• Every passphrase creates a different wallet — losing the passphrase means losing access to that wallet.
• Do not rely on passphrases alone for security; use them as part of a layered defense.
• Document and store any passphrase safely, preferably offline or in a secure vault.

1. Device not detected: Try a different USB cable or port. Use the original cable if possible. Restart your browser and computer.
2. Firmware update failed: Disconnect and reconnect the device, then retry. If issues persist, follow the official recovery instructions on trezor.io/support.
3. Forgot PIN: If you forget your PIN, you must reset the device and restore from your seed. This erases the device — make sure you have the seed available.
4. Seed words don't match during restore: Ensure correct wordlist language and spelling. If necessary, restore with fewer words and incrementally test until you pinpoint the mismatch.
