Why a secure startup matters
Hardware wallets like Trézor provide an air-gapped, tamper-resistant environment to store your private keys. The startup process is the first and most important defense against theft, tampering, or accidental loss. Skipping steps or rushing increases risk. Follow these steps carefully and keep your recovery seed safe — offline and private.

Unboxing & initial inspection
1. What to expect in the box
A standard Trézor package typically includes the device, a USB cable, recovery seed cards, stickers, and a quick-start leaflet. Examine the packaging for signs of tampering: broken seals, torn shrink wrap, or unusual markings.
Visual checks (quick)
- Verify the serial number on the box matches the device label.
- Ensure packaging seal is intact and not resealed.
- Look for scratches or signs of prior use on the device.
Red flags
If anything looks suspicious, don’t connect the device. Contact the vendor or Trézor support and request a replacement. Never initialize a device that may have been compromised.
Prepare your workstation & safety checklist
2. Choose a clean environment
Use a private, well-lit space free of cameras, screens that can be recorded, or curious onlookers. If you plan to record the setup for personal reference, ensure it is stored offline and encrypted.
Essential checklist
- Have pen and the provided recovery seed cards ready.
- Use a personal computer that you trust and that is free of malware.
- Ensure your OS and browser are up to date.
- Do not use public Wi‑Fi for initial setup if possible.
Firmware & official software
3. Always use official sources
Download firmware and the official Trézor Suite or use the browser-based web wallet only from Trézor’s official domains. Avoid third-party downloads. The official start page (linked above in the Office Links) will guide you to the correct downloads.
Verify firmware integrity
During the first connection, the device will either prompt to install the latest firmware or confirm an up-to-date status. Follow on-screen prompts and verify the fingerprint shown in your Trézor Suite matches the one displayed on the device screen.
// Example: high-level flow
1. Connect device via USB
2. Open official app at https://trezor.io/start
3. Follow on-screen instructions to install or update firmware
4. Confirm fingerprint displayed on device matches app
Initializing your Trézor device
4. Start the setup
Power on the device, connect it to your computer and open the official interface. Choose the option to create a new wallet. NEVER import a seed from an unknown source.
Set a device PIN
You will be prompted to set a PIN. Choose a memorable but not guessable PIN. The device will show the PIN entry matrix at random — this mitigates keyloggers.
PIN tips
- Don’t write your PIN on the recovery card.
- Choose at least 6 digits if allowed; avoid repeated patterns.
Create and secure your recovery seed
5. What is a recovery seed?
The recovery seed is a human-readable mnemonic (usually 12–24 words) that encodes your private key. Anyone with this seed can recover your funds, so it must stay secret and offline.
Writing down the seed
Write the seed clearly on the provided card (or on a metal backup for long-term durability). Double-check each word and its order. Consider making multiple physical copies stored in secure locations (safe deposit box, home safe), but avoid multiple easily accessible copies.
Advanced seed storage options
- Use metal seed plates to protect from fire/water.
- Split seed using Shamir’s Secret Sharing (if supported) for distributed backups.
- Consider a safety deposit box for off-site storage.
Using your device: receiving & sending
6. Receive crypto
To receive funds, generate a receiving address in the official app while your device is connected. Always verify the address on the device screen — the software can be compromised, but the device display is the single source of truth.
Send transactions safely
When sending, confirm the recipient address and amount on the device before approving. Review transaction fees carefully.
Multi-account & coin management
Trézor supports multiple coin accounts. Use clear naming conventions in your wallet and segregate funds according to use (savings, trading, spending).
Backup, passphrase & advanced options
7. Passphrase (optional but powerful)
An additional passphrase provides an extra layer by acting as a 25th word. It’s powerful but if forgotten, your funds are irretrievable. Use it only if you understand the trade-offs and have secure, tested backups.
When to use a passphrase
- If you need plausible deniability (hidden wallets).
- To create separate wallets without sharing the same seed.
Passphrase best practices
- Store the passphrase offline (do not take photos).
- Test recovery in a safe environment before committing large funds.
Troubleshooting & support
8. Common setup issues
Connection problems: try a different cable, USB port, or computer. Firmware update fails: retry with the official app; if it persists, contact support. Lost seed: if you still have the device and it’s unlocked, create a new wallet and transfer funds immediately.
When to contact support
- Suspected tampering or pre-used device.
- Firmware flashing errors that you cannot resolve.
- Questions about recovery procedures.
FAQ & best practices
9. Quick FAQ
Q: Can I set up the device without connecting to the internet?
A: You can initialize the device offline for the seed, but firmware updates and the wallet app require a connection. Always use official, secured sources.
Q: Is the recovery seed stored on the device?
A: No. The recovery seed is generated and shown on the device but never stored in plaintext. It must be recorded by you.
Best practices summary
- Buy only from official channels or trusted retailers.
- Keep the recovery seed offline and duplicated in secure locations.
- Use a passphrase only if you have tested recovery procedures.
- Update firmware promptly but verify authenticity each time.
Closing & additional resources
Setting up your Trézor device correctly takes time and attention, but the payoff is control and peace of mind over your crypto holdings. Use the official start link above for guided, up-to-date instructions and reach out to support if anything seems off.
Tip: Practice a recovery on a test device or with a small amount of funds before migrating large balances.
