Quick Overview
This guide covers the essentials you need to securely set up a Trézor device using Trézor.io/Start®. Topics include unboxing checks, initializing or recovering a seed, setting a PIN and optional passphrase, applying firmware updates, and practical safety tips for long-term custody.
Safety First
Before you begin: use a trusted computer, confirm the official URL in your browser, and prepare a durable method to record your recovery seed. Never store seed words digitally or share them with anyone.
Unboxing & Connection
- Inspect packaging for tamper evidence. If anything looks altered, contact official support.
- Connect the device to your computer with a data-capable USB cable.
- Open
https://trezor.io/start
and follow the on-screen onboarding prompts.
Initialize or Recover
Initialize New Device
The device will generate a recovery seed — typically 12, 18, or 24 words. Write them down in order on paper or a metal backup device. Verify each word exactly as shown on the device.
Recover Existing Wallet
Choose recovery, confirm word count, and enter the seed words directly on the device. Never enter your seed into the host computer or upload it to a website.
PIN & Passphrase
- PIN: Set a PIN on the device to prevent unauthorized access if it’s lost.
- Passphrase (optional): Adds an extra secret to derive hidden wallets. Only use this if you can securely store or remember the passphrase.
Firmware Updates
Firmware improves security and functionality. Install updates only through the official Trézor.io/Start process or the verified desktop app. Verify update prompts on the device and avoid third‑party firmware sources.
Test Transaction
After setup, add an account in the official app and send a small test amount to verify receiving and signing workflows. Confirm all transaction details on the device screen before approving.
Seed Backup & Storage
Store your recovery seed offline on a durable medium. Recommended practices include splitting backups across secure locations and using fire- or water-resistant materials. Avoid digital copies or cloud storage.
Ongoing Maintenance
- Keep host software up to date.
- Periodically verify device firmware and check for security advisories.
- For very large holdings, consider multisig or multiple seeds on separate devices.
Troubleshooting
Common Issues
If the device is not recognized, try another cable, port, or the official desktop app. If firmware update fails, follow the recovery instructions on the official support page.
FAQ
Can I set up Trézor completely offline?
Core seed generation happens on-device, but some verification and updates use an internet-connected host. Advanced air-gapped setups exist for experienced users.
What if I lose both device and seed?
Without the recovery seed, funds are unrecoverable. Always make secure backups and consider redundancy strategies.
