What You’ll Need Before You Begin

Step‑by‑Step Setup Process

1. Inspect and Verify

Before powering on, check that your Trezor package is sealed and untampered. Look for holographic seals, stickers, or tamper-evident elements. If anything seems off, stop and contact support.

2. Visit Official Start Page

In your browser, go to https://trezor.io/start. Do not follow links in emails or popups. This official page ensures your setup remains safe and genuine.

3. Download Trezor Suite or Use Web Flow

The start page will present the option to use Trezor Suite (desktop app) or a web-based flow (browser). We recommend using the Suite for a more secure and stable experience.

4. Connect Your Device

Plug your Trezor into your computer via USB. The site or Suite app should detect it. Always confirm that your device screen matches what the app shows.

5. Install or Update Firmware

If your device lacks firmware or an update is available, follow on-screen prompts to install the official firmware. Confirm the prompt directly on the device before proceeding—never skip this verification.

6. Create or Recover Wallet

You can either:

  1. Create new wallet: The device will display a recovery seed (12, 18, or 24 words depending on model). Write these words in the exact order.
  2. Recover existing wallet: Enter your seed phrase to restore access to existing accounts.

After writing your seed, you may be prompted to confirm a few words on the device to ensure accuracy.

7. Set a PIN

Choose a PIN (4–50 digits depending on model). You enter the PIN directly on the device screen (not your computer). This ensures additional security if your device is lost or stolen.

8. (Optional) Enable Passphrase

For advanced users, you may activate a passphrase (think of it as “word 25”) to create a hidden wallet. If used, it must be typed each session and is critical—losing it means losing funds stored in that hidden space.

9. Add Accounts & Select Coins

In Trezor Suite (or the supported wallet you use), add the cryptocurrency accounts you intend to use. Trezor supports many assets—Bitcoin, Ethereum, Cardano, and more.

10. Perform a Test Transaction

Send a small amount of crypto to or from your wallet to verify it's working properly. Always confirm the address and amount displayed on the device before approving.

Security Best Practices

Important: Your **recovery seed** is the master key to your crypto. Anyone with it can access your funds.

Troubleshooting Common Issues

Device Not Detected

Try a different USB port or cable. Restart the app or browser. On Linux, ensure correct udev rules are set so the OS recognizes the device.

Firmware Installation Errors

Make sure your computer is online, disable antivirus/firewall temporarily, and retry. If errors persist, consult official support.

Forgot PIN

After too many failed attempts the device may wipe itself for safety. Use your recovery seed to restore your wallet on a new device.

Lost Device

Your crypto is secure as long as you have your seed phrase (and passphrase if used). Acquire another compatible device and restore using recovery.

Address Mismatch Warning

If the address shown on your computer doesn't match what the device displays, cancel immediately. This indicates potential tampering or malware interference.

What’s Next After Setup?

Frequently Asked Questions (FAQ)

Is Trezor.io/Start the only safe setup option?

Yes. This is the official, secure starting portal. Using third‑party sites puts you at risk of phishing, malware, or cloned setups.

Do I have to use Trezor Suite?

It’s recommended for the full experience. You can also use compatible web or third‑party wallets, but always ensure they support Trezor and never ask for your seed.

What if my device already has firmware or configuration?

You can perform a factory reset or wipe via Suite and follow this setup flow anew. If you suspect tampering, contact official support.

Can I set up using a mobile phone?

Trezor Suite is mainly desktop‑based. Some mobile browsers support WebUSB or OTG flow (especially Model T). Still, desktop is safer and recommended.

What is a passphrase and should I use it?

A passphrase is an extra word or sentence appended to your seed, creating a hidden wallet. If used, you must enter it every time. It increases security but must be managed carefully.

Which coins are supported?

Trezor supports hundreds of cryptocurrencies including Bitcoin, Ethereum, Cardano, Litecoin, many ERC‑20 tokens, and more. Always check current support in Trezor Suite or on the official site.

Is it okay to use public Wi-Fi during setup?

It’s better to use a trusted, private connection. While the protocol is encrypted, avoiding public networks reduces potential interference or attack risks.

Final Thoughts

By following this guide from Trezor.io/Start®, you're ensuring the safest possible onboarding for your crypto device. From firmware verification to seed security, each step matters in protecting your digital assets.
