Introduction
Welcome! If you've landed on this guide, you likely have a brand new Trezor hardware wallet (Model T or One) and want a safe, no-nonsense walk-through to get it working. This guide is written to be friendly for beginners while preserving security best practices that every crypto holder should follow.
Who this guide is for
- First-time Trezor users who want a secure setup.
- People who prefer step-by-step instructions and clear headings (H1–H5 included).
- Readers who want a compact FAQ and quick troubleshooting tips.
Quick safety note
What you will need (Before you begin)
Hardware & accessories
- Your Trezor device (unopened if possible — check packaging seals).
- A USB cable (or USB-C as appropriate for your model) and a computer with a browser.
- Pen and the provided recovery card (or a metal backup if you have one).
Software
- A modern web browser: Chrome, Edge, Brave, or Firefox (latest versions recommended).
- Optionally: Trezor Suite desktop app (download from the official site) — this guide covers the web-based start at trezor.io/start.
Step-by-step setup
Step 1 — Inspect the device
Check the box and device for tamper evidence. If packaging is damaged or seals look tampered, contact support (use the colorful links above).
Step 2 — Connect the device
- Plug the Trezor into your computer using the supplied cable.
- Open your browser and go to trezor.io/start (or launch Trezor Suite if you prefer a desktop app).
Step 3 — Install firmware (if required)
New devices may require a firmware update before first use. The Start page will detect and guide you through any firmware installation steps. Always only install firmware provided/signed by Trezor.
Tip
Step 4 — Create a new wallet
- Choose Create new when prompted.
- Pick a PIN code directly on the device. PINs are entered via the on-screen layout on your computer but confirmed on the device—this prevents keyloggers from learning the PIN digits’ positions.
- Write down your recovery seed exactly as shown on the device. The length is typically 12 or 24 words depending on your model/choice. Use the recovery card and write clearly — double-check spelling.
Why the seed matters
The recovery seed is the master key to all your accounts on the device. If your Trezor is lost or damaged, the seed lets you restore funds on a new device. If someone gets your seed, they can steal your funds — protect it accordingly.
Step 5 — Verify & finish
- The device will ask you to re-confirm some seed words or otherwise verify the seed is written correctly — follow on-screen prompts.
- When setup completes, your wallet will display an address; you can use this for receiving funds or exploring balances in Trezor Suite.
Intermediate: Hidden wallets, passphrases and best practices
Using a passphrase (optional advanced feature)
Trezor supports an optional passphrase which acts like an extra word in addition to your seed. This creates a hidden wallet. Use passphrases only if you understand their implications: if you forget the passphrase, the funds in that hidden wallet are lost permanently.
Pros and cons
- Pros: Adds plausible deniability and extra security.
- Cons: Increased complexity, easy to lock yourself out if you forget the passphrase.
Recommendation
If you're new, skip the passphrase until you understand how it works and have secure, tested backups.
Security checklist (short)
- Always buy hardware directly from the official shop or authorized reseller.
- Never enter your seed into a computer or phone.
- Use a PIN and enable passphrase only if you fully understand it.
- Keep at least one offline, fireproof backup of your seed (metal if possible).
- Check firmware authenticity and only use official software.
Common troubleshooting
Device not detected
- Try a different USB cable or port (avoid USB hubs).
- Reboot the computer and retry.
- Visit Support: support.trezor.io.
Seed words missing / damaged
If part of your seed is unreadable, stop using that seed immediately and recover to a new device using whatever words you still have — only do this if you understand the risk. Ideally, keep multiple secure backups.
Lost device
Use your recovery seed on a new Trezor (or compatible wallet) to restore funds. Revoke any third-party session authorizations and change passwords where you stored wallet metadata.
Advanced: Using Trezor with external wallets & services
Trezor can integrate with many third-party wallets and services (e.g., Electrum, MyEtherWallet); always follow the official documentation for compatibility steps and only connect to trusted services.
Example: Viewing an address (read-only)
- Open Trezor Suite or a connected external wallet.
- Go to the receive tab and verify the address shown on your Trezor's physical screen matches the one in the app before sharing it.
FAQ — Frequently Asked Questions
Top questions answered
- Q: What happens if I lose my Trezor?
- A: Your funds are safe as long as you have your recovery seed. Restore the seed on another Trezor or compatible wallet to regain access.
- Q: Can I enter my seed into a computer to save it?
- A: Never type your seed into a computer, phone, or website. Only write it down on paper or store it in an offline, physical medium (metal backup recommended).
- Q: Is Trezor open source?
- A: Trezor firmware and much of the software is open source — check the official repo links on the Trezor website for code and audits.
- Q: How often should I update firmware?
- A: Update when official firmware releases are announced and when the device prompts you. Updates often include security improvements — verify authenticity on-device.
- Q: What is a passphrase and should I use one?
- A: A passphrase is an optional extra secret that augments your seed; it creates a separate hidden wallet. Use it only if you understand the risk of permanent loss.
- Q: Can I use my Trezor with mobile?
- A: Yes — Trezor Suite offers mobile support and some third-party mobile wallets integrate with Trezor via USB-OTG or Bluetooth accessories (Model T typically supports USB-OTG). Check official docs for compatibility.
- Q: Is it safe to buy a used Trezor?
- A: Buying used devices is risky. If you do, perform a full factory reset and reinstall firmware before use, and treat the device as compromised until you can confirm integrity. Buying new from the official shop is recommended.
- Q: Where can I get official help?
- A: Use the official Support and Docs links above: support.trezor.io and trezor.io/guide.
- Q: What if I see a different address on my computer than on my device?
- A: Trust the device screen. If the addresses don't match, do not proceed with the transaction, and investigate (possible malware or compromised host).
- Q: Can someone access my funds if they get my PIN?
- A: They can access the device but only if they also have the recovery seed or know the passphrase. Use a strong PIN and keep your seed secure.

Final tips and closing thoughts
The strongest protections are simple: keep your seed offline, update firmware from official sources, and verify everything on the device screen. Hardware wallets like Trezor are powerful tools — treat them with the respect you'd give a physical safe.
