Trezor.io/Start — Official Trezor® Setup & Quickstart Guide

Overview

Trezor.io/Start is the verified starting point for every Trezor® hardware wallet. The guide ensures your device is authentic, that only signed firmware is installed, and that your private keys are created and stored offline on the device itself. This quickstart is intentionally direct and security-first: complete each step exactly as shown on your device screen.

Devices configured via Trezor.io/Start provide cold storage protection. Your recovery seed is the single key to wallet recovery — protect it offline and treat it as the highest-value asset.

Quickstart — Core Steps

1. Unbox and inspect. Confirm packaging integrity and that accessories match the included contents.
2. Connect the device. Use the supplied USB cable to connect your Trezor to a trusted computer.
3. Open Trezor Suite. Install and launch the desktop application that manages firmware, accounts, and transactions.
4. Verify firmware. During first use, the device will prompt firmware installation; accept only signed firmware presented by Trezor Suite.
5. Create wallet & seed. Generate a new wallet on the device. Write down the recovery seed words exactly as shown—do not store them digitally.
6. Set a PIN. Choose a unique device PIN; this protects local access and the on-device interface.

Complete these steps in order. The device display is the authoritative source of truth for all actions and confirmations.

Security Principles

Trezor hardware isolates private keys inside a secure element. Key security principles you should rely on:

• Device-level confirmation: Transactions and login requests must be confirmed on the device display.
• Signed firmware only: The device accepts only firmware signed by Trezor cryptographic keys.
• Seed backup: Recovery words are the only reliable way to restore funds—keep them offline and physically protected.
• Optional passphrase: For advanced users, an additional passphrase creates a hidden wallet layer beyond the seed.
• Open auditability: Firmware and tools are publicly auditable, enabling independent security review.

Best Practices

• Always use the original cable and avoid USB hubs during setup.
• Never enter your recovery seed on a computer, photo, or cloud service.
• Create multiple offline backups of the seed and store them in separate secure locations.
• Confirm every transaction’s address and amount on the device before approving.
• Keep device firmware and the Trezor Suite app updated; updates include critical security improvements.

If anything about your device or setup appears unexpected, pause and verify; do not proceed until you are certain the environment and device are correct.

Frequently Asked Questions

Q1: What does Trezor.io/Start do?
A: It guides you through installing Trezor Suite, verifying firmware, generating a private key on the device, and backing up the recovery seed.

Q2: Can I restore an existing wallet?
A: Yes. Use your recovery seed to restore a wallet on your Trezor device during the setup process.

Q3: Is the recovery seed stored anywhere online?
