Overview

Trezor is a hardware wallet that stores your crypto private keys offline. This guide gives a clear, practical setup process for a new Trezor device, whether you're using Trezor Model T or Model One. Follow every step carefully — hardware wallets are only as secure as the setup.

Before you begin

  • Make sure you bought your device from an official retailer or trezor.io to avoid tampered units.
  • Use a clean computer and a secure network — avoid public Wi‑Fi.
  • Have a pen and the included recovery card ready (or paper) — you will write down the recovery phrase.
  • Never share your recovery phrase with anyone — Trezor staff will never ask for it.

Quick setup steps

1

Unbox & inspect

Check tamper-evident seals and packaging. Verify the hologram and packaging integrity. If anything looks suspicious, contact the vendor or trezor.io support.

2

Go to trezor.io/start

Open the official site on your computer to download Trezor Suite or follow web-based onboarding. Always verify the URL and certificate. We strongly recommend downloading the official Trezor Suite app for desktop for the smoothest experience.

3

Connect your device

Use the supplied cable to connect the Trezor to your computer. If prompted, allow the browser to access the device. Don't install unofficial drivers — use the prompts from trezor.io.

4

Install Trezor Suite

Download and run the official Trezor Suite, which will guide firmware updates (if needed) and wallet setup. Follow on-screen instructions and approve actions on the device display when asked.

5

Create a new wallet & backup

When prompted, choose to create a new wallet. The device will generate a recovery seed phrase (typically 12, 18 or 24 words). Write it down exactly in the order shown. Store copies in separate secure locations.

6

Set a PIN

Choose a PIN on the device. The PIN prevents unauthorized physical use. Make it memorable to you but hard to guess. The device will never show the PIN on your computer screen.

7

Verify your setup

Trezor will ask you to confirm parts of the recovery phrase and may perform a device verification. Confirm everything matches your written backup.

8

Receive a small test transfer

Before moving large amounts, receive a small test transaction to verify the addresses and flow are correct.

Best security practices

  • Never enter your recovery phrase into a computer or phone. Write it down on paper or metal backup plates.
  • Keep at least two secure backups of the recovery phrase in different physical locations (e.g. safe deposit box, home safe).
  • Consider passphrase protection (hidden wallet) only if you understand its implications — losing the passphrase means losing access permanently.
  • Keep firmware updated — but only through official tools. Beware of phishing and fake updates.

Troubleshooting & tips

  1. If the device is not recognized, try different USB ports and cables. Reboot computer if necessary.
  2. If firmware update fails, don’t power cycle mid‑update. Follow trezor.io support steps.
  3. If you lost your seed, and you have remaining access, move funds to a new wallet immediately and create a new backup.
  4. For advanced users: consider multisig setups for additional security.

Developer note: verifying addresses

For maximum security, always verify receiving addresses on the device screen before sending funds. This prevents man-in-the-middle attacks where a compromised computer shows a different address than the hardware device.

FAQ

Can I set up Trezor without Internet?

You can generate the seed offline by using an air-gapped installation, but connecting to Trezor Suite or trezor.io might be necessary for firmware updates and coin support. Advanced users use offline setups for additional security.

What to do if I lose my Trezor?

If you have your recovery phrase, you can restore your wallet on a new device or compatible wallet. If you also lost your recovery phrase, the funds are likely unrecoverable.

Are there alternatives?

Yes: Ledger, Coldcard, and other hardware wallets exist. But follow vendor-specific setup instructions and purchase from official channels.
