Welcome
This guide walks you through setting up your Trezor device from scratch using the official onboarding flow. Every step is designed to keep your funds safe and your setup secure. Follow carefully, and don’t skip any parts.
Why Use Trezor.io/Start?
Trezor.io/Start is the **official launchpoint** for Trezor device initialization. Using this ensures you are:
- Downloading the correct and latest software (Trezor Suite)
- Updating and verifying firmware via trusted channels
- Preventing phishing or spoofed setups
- Guided through seed generation, PIN, and security best practices
Always double‑check the URL in your browser: it should read https://trezor.io/start. Bookmark it, and avoid clicking unfamiliar links or ads.
Before You Begin
What You’ll Need
- One Trezor device (Model One or Model T) — new or factory reset
- The USB cable included in the box (avoid untrusted or faulty cables)
- A computer (desktop or laptop) with up‑to‑date system and browser
- Pen and the recovery seed sheet (or metal backup option)
- A private, distraction‑free environment (no cameras, no prying eyes)
Security Reminders
- Never photograph or screenshot your recovery seed.
- Never type your seed into a website, phone, or computer.
- Always verify prompts on the device screen before accepting actions.
Step‑by‑Step Setup
1. Inspect the Package
Before opening, check that the packaging is intact and the seal or hologram is untampered. If anything feels off, contact support. The device should not display any seed or wallet information when first powered on.
2. Connect & Open the Official Portal
Plug the Trezor into your computer using the included cable. In your browser, navigate to:
https://trezor.io/start
This portal will detect your device and guide the appropriate setup flow. Keep it open while you work.
3. Download and Install Trezor Suite
The portal will prompt you to download the official Trezor Suite desktop application (or use the web version if supported). We recommend the desktop version for best compatibility, security, and full features.
Install the software for your OS (Windows, macOS, or Linux). Launch it and allow it to connect to your Trezor.
4. Firmware Installation & Genuine Check
If your device has no firmware or an update is needed, Suite will prompt you to install it. Follow instructions, confirm prompts on the hardware device, and wait until the process completes.
After firmware is installed, a **genuineness check** is performed. The device and software verify each other to confirm integrity.
5. Create a New Wallet
In Suite, choose “Create New Wallet”. The device will generate a new recovery seed (commonly 12 or 24 words). Write down each word on the recovery card, in the exact order displayed.
Confirm a few words back on the device when prompted. This ensures your physical backup matches the seed.
6. Set a Strong PIN
You’ll next choose a PIN (typically 4–9 digits). Use the on‑device interface to enter it. Confirm it correctly. This PIN protects your device locally—do not use easy sequences like “1234” or birthdays.
7. (Optional) Enable Passphrase Protection
For added security or privacy, you can enable a passphrase (sometimes called a “25th word”). This is optional but provides a hidden wallet if used correctly. Memorize it—losing the passphrase means losing access to that wallet.
8. Add Accounts & Send a Test Transaction
In Suite, you can now add accounts for your supported coins (Bitcoin, Ethereum, etc.). To validate everything is working, send a small test amount to your own receive address.
Always verify the receive address on the **device screen** before sharing it.
Security Best Practices
Do’s
- Store the written seed offline, securely, and in a safe place (fireproof safe, safe deposit box, etc.).
- Use multiple backups, stored in separate locations.
- Always verify addresses and transactions on the device screen.
- Keep Suite and firmware updated via official channels only.
- Bookmark the official portal (trezor.io/start) and never follow suspicious links.
Don’ts
- Never share your seed or passphrase with anyone — not even support.
- Never store your recovery words electronically (photo, notes, cloud, etc.).
- Never use untrusted software or browser extensions claiming to support Trezor.
- Don’t skip verification on-device — attackers can spoof browser displays.
Troubleshooting & FAQs
Device Not Detected?
Try another USB port or cable. Reboot the computer or Suite. On Linux, ensure correct udev rules. Make sure no firewall or antivirus is blocking the connection.
Forgot PIN?
The device will wipe itself after multiple incorrect attempts. Use your recovery seed to restore the wallet on a fresh device.
Lost Device?
If the hardware is lost or damaged, you can restore your wallet (and funds) using your recovery seed (and passphrase, if used) on a new Trezor.
Mismatch Address Warning?
If the address shown on your computer differs from the one on your device, cancel, disconnect, and troubleshoot. Do not proceed until they match.
Is Passphrase Mandatory?
No — passphrase is optional. It adds a layer of security but comes with greater responsibility. Use it only if you understand the implications.
