Before you begin — quick safety checklist
Confirm these before starting: device seal intact, official download source, offline seed backup method, and a clean computer. If anything looks off, stop and contact support.
1) Unboxing & initial checks
When your Trezor arrives, inspect the anti‑tamper seal and packaging. The box should contain the device, a USB cable, recovery seed card, and quick start materials. If the seal is broken or contents are missing, contact the vendor immediately.
2) Download Trezor Suite
Always download Trezor Suite from trezor.io/start. Avoid search results that look suspicious. Suite is available for Windows, macOS and Linux and includes the latest security updates and the integrated Bridge required to talk to your device.
Step A — Install
Run the installer and follow the on‑screen prompts. Grant necessary permissions for USB access.
Step B — Connect
Use the supplied USB cable. Connect your Trezor and unlock it when prompted.
3) Initialize device & firmware verification
Trezor will prompt to install firmware if required. Firmware validation is crucial — Suite will verify signatures and you must confirm the hash on the device display. Never approve a firmware update without verifying the prompt on the device itself.
Why firmware matters
Firmware is the code running on your device. Signed firmware prevents tampered updates. The verification step is your last line of defence against malicious modifications.
4) Create PIN & enable passphrase (optional)
Set a PIN to protect local device access. Choose a PIN you can remember but that isn't easily guessable. For an extra privacy/security layer, enable a passphrase — this creates hidden wallets derived from your seed. Treat passphrases as separate secrets: they are NOT stored on the device and cannot be recovered from the seed alone.
5) Write down your recovery seed
The device will generate a 12/24‑word recovery seed. Write it down on the provided card or preferably use a metal backup plate for long‑term durability. Store it offline in a secure location — this seed is the ultimate backup: whoever has it can restore your wallets.
6) Add accounts & manage metadata
Open Trezor Suite and add accounts for the coins you use — Bitcoin, Ethereum, and supported altcoins. Use Suite's labeling/metadata feature to attach human‑readable names to accounts and addresses. Labels are encrypted and can be synced via Google Drive or Dropbox, or stored locally. If you plan to use Suite on multiple devices, enable encrypted cloud sync to keep labels consistent.
7) Sending & receiving funds
To receive, generate an address in Suite and verify it on the device screen before sharing. When sending, always confirm the destination address and amount on the Trezor display: the device is the only trusted UI for transaction confirmation. For Bitcoin users, consider coin control to reduce address linkability.
Pro tip — Verify addresses
Never copy/paste addresses from untrusted sources. Always verify the address on your device's screen before approving the transaction in Suite.
8) Backup, recovery & testing
After setup, practise a full recovery on a spare device (or virtual machine) to ensure your seed is correct and readable. This test prevents surprises if your primary device is lost or damaged. Treat recovery testing as an essential part of your backup plan.
9) Advanced features & privacy
Trezor supports passphrase‑derived hidden wallets, UTXO coin control, Tor routing in Suite, and watch‑only exports of XPUBs for monitoring. Combine these tools for high‑privacy workflows: e.g. use hidden wallets for sensitive funds and a watch‑only machine for bookkeeping.
10) Security hygiene & common pitfalls
- Only download Suite from the official site.
- Never type your recovery seed into a computer or phone.
- Use a hardware PIN manager rather than reusing passwords.
- Be cautious of phishing sites and cloned domains.
11) Troubleshooting
- Device not detected: check cable, USB port, and permissions; restart Suite.
- Firmware update failed: retry on a stable connection; consult Trezor support.
- Missing labels: confirm whether metadata was stored locally or synced to cloud.
When to contact support
Contact official Trezor support if you suspect tampering, firmware anomalies, or if you lose your seed and need recovery assistance. Do not share seed words or passphrases with anyone claiming to be support.
12) Best practices summary
- Verify package integrity and download Suite from trezor.io/start.
- Install firmware only after verifying the device prompt.
- Write your recovery seed offline and test recovery.
- Use PIN + passphrase where appropriate and enable encrypted metadata sync if using multiple devices.
- Confirm every transaction on the device display.
Final thoughts
Starting your Trezor device is straightforward when you follow clear, security‑first steps. The combination of Trezor Suite and a hardware wallet gives you a powerful setup for long‑term custody, day‑to‑day transactions, and privacy‑conscious workflows. Regular maintenance — firmware updates, secure backups, and education about phishing — will keep your crypto safe for years to come.
