Trezor.io/Start | Starting Up Your Device

Before you connect a Trezor device, make sure you are using a secure computer and network. Avoid public Wi‑Fi and shared terminals. Prepare a pen and the manufacturer-supplied recovery card or several sheets of paper for your seed. Have a private, offline place to store your seed and backups. These simple preparation steps reduce the chance of mistakes.

1. Download only from: Trezor.io/start. Confirm the address and use an official HTTPS connection. The official site includes firmware images and verification tools.
2. Inspect packaging: Look for tamper-evident seals. If seals or plastic are torn or look suspicious, contact support via official channels before proceeding.
3. Disconnect unnecessary peripherals: Turn off screen-sharing, remove unknown USB devices, and disable automatic backups to cloud services during setup.

A note on terminology: This guide uses the word "seed" and "recovery phrase" interchangeably — both refer to the human-readable words that allow recovery of your wallet. Keep them secret and offline.

You will be asked to create a PIN. The PIN protects the device from casual physical access. Choose a PIN that is not easily guessable — avoid birthdates, repetitive numbers, or short sequences like 1234. Use the device buttons to select digits so the PIN never appears in the host OS input buffer.

Choose a device name that helps you identify it (for example, "Home‑Trezor"), but do not use personally identifying information that you would not want associated with your crypto holdings.

If you use a long PIN, ensure you will remember it. The device will lock after a number of incorrect attempts, and a strong PIN paired with a recovery seed provides layered protection.

A passphrase is an optional secret added to your seed. Think of it as an additional word you never write down. The passphrase can add plausible deniability: two different passphrases used with the same seed unlock entirely different wallets.

However, passphrases are powerful and dangerous if mismanaged. Document your strategy for recovery, ensure you (and only you) can reproduce the passphrase, and consider professional custody for very large holdings.

• If you lose the passphrase, the funds are effectively unrecoverable — treat it like a master key.
• Never store the passphrase with the seed; store them separately if written down at all.

1. Offline backups: Store physical backups in different, secure locations (bank safety deposit box, home safe, or another trusted facility).
2. Redundancy: Consider metal seed backup solutions for fire/water resistance.
3. Regular checks: Periodically verify that your seed is readable and intact, and that you know the access procedure.
4. Beware of phishing: Only use links you trust — prefer typing Trezor.io/start yourself instead of clicking random links in email or forum posts.
5. Share little: You may tell a trusted partner how to find your recovery instructions, but never reveal specific seed words or passphrases.

Security is cumulative: small habits add up. The combination of a secure PIN, a safely stored seed, and cautious online behavior drastically reduces risk.

Trezor devices use a secure element and deterministic seed generation standards (BIP‑39/32/44, depending on coin) to derive keys. The private keys never leave the device; the host computer only sends transaction data that is signed inside the hardware. This architectural separation is the core defense against remote compromise.

Because Trezor signs on-device, even if the host computer is infected with malware, the attacker cannot extract private keys. That said, attackers can still attempt phishing or social engineering to trick you into broadcasting a transaction that transfers funds. Always confirm transaction details on the device's screen.

For larger holdings or organizational use, consider multisignature setups. Multisig spreads control across multiple keys and devices, increasing security and reducing single-point-of-failure risk. Trezor devices can participate as one keyholder in many multisig schemes; consult dedicated multisig guides for step-by-step instructions.

For corporate custody, combine hardware devices with institutional procedures: audits, cold storage policies, and defined recovery leadership for emergencies.

If you suspect tampering, contact the vendor or Trezor support via official channels listed on Trezor.io/start. Keep receipts and order metadata in a secure place in case you need warranty service.

Never rely on third-party sellers who cannot verify origin. If you purchased through an unofficial channel, verify authenticity before initializing.

• Always start with Trezor.io/start for downloads and verification.
• Keep your recovery seed offline and secure — the seed is the single-most-important secret.
• Choose a strong PIN and consider passphrase protection only if you understand the tradeoffs.
• Test your recovery plan on a separate device before trusting a backup.
• Use unique passwords, email hygiene, and 2FA for associated accounts.

Setting up your Trezor correctly at the outset creates a foundation of security that will protect your assets for years. By following the official flow at Trezor.io/start, verifying firmware, writing down your recovery seed carefully, and keeping secrets offline, you greatly reduce the chances of loss.
