The journey into true digital asset ownership begins with a commitment to **self-custody**. Your Trezor device is the ultimate tool for this mission, providing an isolated environment to secure your private cryptographic keys. This guide walks you through the official and safest initialization process via the $\text{Trezor.io/start}$ portal, ensuring your digital wealth is protected from the very first moment.
Before connecting your new device, a brief period of preparation is essential to guarantee a secure environment.
Open your preferred, up-to-date web browser and navigate directly to Trezor.io/start. This site serves as the official, secure starting point for all Trezor users and will guide you to download the necessary companion application, **Trezor Suite**.
Connect your Trezor device to your computer using the original cable. On the $\text{Trezor.io/start}$ page, you will be prompted to download and install the **Trezor Suite** desktop application. We highly recommend the desktop application for the best security and user experience, though a web version is also available. Follow the instructions to complete the installation of the software.
The Trezor Suite application will now guide you through the initial firmware installation. This essential software is what makes your device operate. The Suite will also perform a critical authentication check to verify that your device is genuine and unaltered. Follow the on-screen prompts and confirm all actions on your physical Trezor screen. This step should only take a few moments.
This is the most crucial part of the entire process. The creation of your wallet and the secure recording of your unique recovery phrase (also known as the wallet backup) are the ultimate safeguards for your digital assets.
Within Trezor Suite, select the option to **Create New Wallet**. Your Trezor will now internally generate a unique, cryptographically secure sequence of random numbers that represents your ownership. This sequence is **never** visible to the computer—it stays locked inside the device.
You will be prompted to begin the backup process. Your Trezor device will display a series of words (12, 18, or 24 words, depending on the model and settings) one at a time. This sequence is your **Recovery Phrase** or **Wallet Backup**. It is the only way to recover access to your assets if your physical device is lost, stolen, or damaged.
Write down each word, in the exact order, on the recovery card(s) provided. Do not use your computer, a picture, a cloud service, or any other digital medium. This phrase must be kept **physically offline** and secured in a private, protected location.
Trezor Suite will guide you through a confirmation step to ensure you have correctly recorded the phrase. The device may ask you to confirm specific words from your recorded list. This is a vital practice run for a potential recovery. If the verification is successful, your wallet backup is complete and confirmed.
To protect your device from unauthorized physical access, you must set a **PIN** (Personal Identification Number). This code is entered on the Trezor screen itself (the order on the Suite interface changes with each use for security). Choose a memorable but complex PIN—four to six digits is standard, but the maximum is often higher for enhanced security. This PIN is required every time you connect your device to authorize management of your assets.
With your wallet initialized and your backup safely secured, you can now explore the advanced features and prepare for transaction security.
The Trezor Suite application is your secure interface for managing your digital assets. You can now:
A core tenet of hardware wallet security is on-device verification. When you prepare to receive or send assets:
Receiving Assets: Generate a recipient address in Trezor Suite. The **exact same address** will be displayed on your Trezor device screen. You must visually compare and confirm that the address on the computer screen precisely matches the one on the physical Trezor device before sharing it or proceeding. This guards against malware that could attempt to substitute the address on your computer.
Sending Assets: Similarly, when you initiate a transfer, the final recipient address and the transaction amount will be displayed on your Trezor device. You must review and confirm these details on the physical device using its buttons before the transaction is signed and broadcast to the network.
For advanced users, Trezor offers the option of adding a **Passphrase**. This is a user-defined word or sentence that acts as an extra layer of protection, creating a separate, hidden wallet. The passphrase is never stored on the device or the recovery phrase. Caution: If you use a passphrase and forget it, the assets secured by it are permanently inaccessible, even with your original recovery phrase. Store it with the same level of care as your recovery phrase, but ideally, in a separate, secure location.
By completing the setup through the official $\text{Trezor.io/start}$ portal and following these steps, you have successfully taken control of your cryptographic keys and your digital future. Your Trezor is now a cold-storage vault, ensuring that your private keys are isolated from the vulnerabilities of the connected world. Embrace the principles of self-custody and remember that the security of your assets ultimately rests on the physical, offline safety of your unique wallet backup phrase.
Congratulations on securing your digital assets!
