Quick checklist (before you begin)
- Use a clean, offline surface and a private space for setup.
- Have a pen and the included recovery card or paper ready — never type the seed into a computer or phone.
- Only download official software from trezor.io/start.
- Do not share the recovery seed, PIN, or passphrase with anyone.
1. Unboxing & Hardware inspection
Inspect packaging for tamper evidence. Confirm device model (Trezor One / Trezor Model T) and look for the holographic seal or tamper indicators as described in the official documentation.
2. Software: Trezor Suite or Web
- Visit trezor.io/start and download Trezor Suite for your OS, or use the recommended web flow.
- Verify the download when possible (checksums/signature) — this prevents counterfeit installers.
- Install and open Trezor Suite; keep your system's antivirus on but be wary of false positives during device communication prompts.
3. Connect device & Initialize
- Connect the Trezor to your computer using the supplied USB cable.
- Follow on‑screen instructions in Suite: choose Create new wallet or Recover wallet if migrating.
- When creating, the device will generate a recovery seed — write every word in order, on the physical card. Do not store the seed digitally.
Important: Trezor never asks for your recovery seed online. Any request to enter the seed into a website or to share it is a scam.
4. Set a PIN
Choose a PIN you can remember but that others cannot guess. The PIN prevents unauthorized local access and is required every time the device is used.
5. Optional: Passphrase (Advanced)
A passphrase creates a hidden wallet. It strengthens security but adds responsibility — losing the passphrase means losing access. Use only if you understand the implications.
6. Firmware & Device Updates
- After initialization, check for firmware updates in Trezor Suite and apply them when prompted. Firmware keeps the device secure and compatible.
- Only update firmware via Trezor Suite or official instructions — never from third‑party links.
7. Install coin apps & Add accounts
Within Suite, install coin apps (e.g., Bitcoin, Ethereum) and add accounts. Trezor supports many coins and tokens; you can add multiple accounts per coin.
8. First transaction (recommended test)
- Send a small test amount to your new address to verify setup.
- Confirm the address on your Trezor screen — always verify addresses on‑device before receiving funds.
Troubleshooting & Support
- If Suite doesn't detect your device: reconnect, try another USB port/cable, or restart Suite.
- On Linux, ensure udev rules are set (follow the official guide).
- For persistent issues, visit trezor.io/support and collect Suite logs for support staff.
Safety reminders
- Never enter your recovery seed into a website, app, or chat — it must remain offline.
- Beware phishing — always check the domain and use bookmarks for trezor.io.
- Use hardware PIN and consider a passphrase for high‑value storage.
