Trezor Setup Guide

Start Setup

Mastering Self-Custody. Your Step-by-Step Trezor Suite Guide.

The Trezor Suite is your secure command center. This guide provides the official, step-by-step instructions needed to initialize your device, install the necessary software, and secure the two most critical defenses of your crypto wealth: the Recovery Seed Phrase and your device PIN.

Begin Setup Process
1

Verify Package & Download Trezor Suite

The first step is a physical security check. Before connecting your Trezor to your computer, **carefully inspect the packaging**. Ensure the seals or holographic stickers are completely intact, with no signs of tampering, tears, or prior opening. A genuine Trezor device comes in tamper-evident packaging to assure you are the first person to interact with it. If anything looks suspicious, **stop and contact Trezor support immediately.**

Once verified, you need the official software. **Trezor Suite** is the dedicated, all-in-one application (available for desktop and web) that you'll use to manage your device. **Crucially, only download the software from the official Trezor website.** Searching for it elsewhere risks downloading malicious phishing software. The desktop application is recommended for maximum security isolation.

Action Checklist:

  • **Inspect:** Confirm all physical seals on the Trezor box are unbroken.
  • **Download:** Go to the official Trezor download page and install the Trezor Suite desktop app.
  • **Prepare:** Have your Trezor device, the provided USB cable, and the physical recovery seed cards ready.

Connect Device & Install Official Firmware

Now, connect your Trezor device to your computer using the supplied **USB cable**. Launch the **Trezor Suite** application. The Suite will detect your device, which, if it's new, will not yet have any operating software (firmware) installed. This is a deliberate security featureā€”no pre-installed firmware means no tampering.

The Suite will automatically prompt you to install the latest official firmware. This software allows the device to function. During this process, you will be required to **confirm the installation directly on the Trezor device's physical screen**. This step ensures that only genuine, verified software is installed, controlled by your physical interaction with the device. Never install firmware if your computer or the Trezor Suite asks for confirmation *without* the corresponding prompt appearing on the Trezor device screen.

Firmware Key Check:

**CRITICAL:** Always verify the **fingerprint** (a long security code) displayed on the Trezor device screen matches the one displayed on the Trezor Suite application before confirming the installation. This is your final verification that the software is official.

Create and Secure Your Recovery Seed Phrase

This is the **most important security step**. The Recovery Seed Phrase (usually 12, 18, or 24 words) is the master key to your funds. If your Trezor is lost, destroyed, or stolen, this phrase is the *only* way to restore access to your crypto on a new device.

The Trezor Suite will now guide you to generate the seed. The words will be generated **offline, inside the Trezor device**, and displayed **only on the device screen**. You must manually write these words down on the provided physical recovery cards.

šŸšØ Strict Security Protocol:

  • **NEVER Digitalize:** Do not take photos, type, screenshot, or store your seed phrase on any internet-connected device (computer, phone, cloud).
  • **Write Down and Verify:** Write the words clearly and verify the spelling immediately.
  • **Secure Storage:** Store the physical copy in a safe, hidden, and fire/waterproof location. This backup should only be accessible by you.

After writing down the seed, the Suite will guide you through a **verification process** to ensure you copied it correctly. Take your time. Once the setup is complete, the seed will not be displayed again.

Define Your PIN and Passphrase Layers

Your Trezor uses a **PIN** (Personal Identification Number) to protect the device from unauthorized physical access. The Trezor Suite will prompt you to set a PIN (4 to 9 digits). **Pay close attention:** the PIN layout is displayed randomly on the Trezor screen, but you enter the corresponding digits using the static number pad layout on your computer screen. This trick prevents keyloggers from capturing your PIN.

The Optional Passphrase (25th Word)

The **Passphrase** is an **advanced, optional, but highly recommended** security feature. It acts as a 25th word that creates a **"hidden" wallet** tied to your existing seed phrase. Without the passphrase, your crypto remains invisible, providing an extra layer of defense against sophisticated physical attacks.

The passphrase is **never stored on the Trezor device itself**. If you use it, you must **memorize it perfectly** or securely back it up separately from your main seed phrase. Losing the passphrase means permanent loss of access to the funds stored in the hidden wallet. Choose a complex passphrase and use this feature only if you are confident in your ability to manage this extra layer of complexity.

Final Action:

Once the PIN is set, your Trezor is fully configured! Trezor Suite will load your dashboard. You can now use the receive function to get your addresses and securely transfer funds from exchanges or other wallets into the safety of your hardware wallet.

Post-Setup FAQs

A secure connection is confirmed when Trezor Suite displays the status as "Connected" and requests you to enter your PIN or confirm a transaction *on the physical Trezor screen*. Crucially, your Trezor device will display the transaction details (address and amount) for you to manually verify before you physically press the confirmation button.

No. When you set up your Trezor, it generates a brand-new, unique **Recovery Seed Phrase** and, consequently, new public addresses. You must use the **new receive addresses** generated by the Trezor Suite. If you want to move funds, you must perform an external transaction from your old wallet to your new Trezor address.

You have a limited number of attempts before the device wipes itself (a security measure). If you have forgotten the PIN, the recommended procedure is to let the device wipe itself after too many failed attempts, and then **restore it immediately** using your **Recovery Seed Phrase** on the Trezor Suite interface. The wiping action is a security feature that protects your crypto from physical thieves, but your funds are safe as long as you have your seed phrase.
