Step 1: The Secure Handshake and Software Acquisition
Your first action is connecting your new Trezor device to your computer. Once the device screen illuminates, a direct, manual navigation to the official resource is required. To manage your assets, you will need the primary companion application.
- Manual Navigation: Ensure you have typed the correct address into your browser. This bypasses any risk from compromised links.
- Acquire Trezor Suite: Download the dedicated desktop application directly from the official link provided on the setup page. This application is your safe, authenticated window to your digital vault.
- Hardware Integrity Check: Before proceeding in the software, visually inspect your device packaging and seals. Any sign of tampering warrants immediate action: do not proceed and contact official support.
Step 2: Securing the Core — Firmware and New Identity
Your device will next require a firmware installation, the cryptographic operating system that guarantees its security. This is followed by the creation of your unique digital identity.
- Firmware Installation: The Suite will prompt you to install the latest, officially signed firmware. Confirm this update on your physical device. Never interrupt this process.
- New Identity Generation: Select the "Create New Wallet" option. This critical step generates your private keys—the secret numbers that control your funds—entirely within the protected chip of your Trezor.
Step 3: The Irreplaceable Wallet Backup (Your Ultimate Recovery Key)
This is your single chance to secure your access for life. The wallet backup (a sequence of 12, 18, or 24 words) is the only way to recover your funds if your physical device is lost or destroyed.
- Physical Transcription: Your Trezor screen will display the sequence word by word. You must write this down *only* on the provided physical backup cards.
- Absolute Offline Storage: Do not ever take a photograph, scan, or type this sequence into any device connected to the internet. Store the cards in a safe, secure, fire-resistant location.
- Crucial Verification: The Suite will initiate a process to verify key words from your transcription. Follow the instructions precisely to confirm accuracy before finalizing.
Step 4: Access Protection and Final Configuration
The final steps involve establishing the physical access barriers to your hardware device.
- Establish the Device PIN: Set a strong PIN. You will enter this on a scrambled virtual keypad displayed in Trezor Suite, referencing the pattern on your physical device. This makes the PIN resistant to common keylogging attacks.
- Device Naming: Assign a recognizable name to your Trezor. This is a small, but useful organizational step.
- The Advanced Passphrase: Consider enabling the optional Passphrase. This acts as a powerful 25th word, creating a separate, hidden vault. If enabled, remember: forgetting this word means permanent loss of access, as it is not stored anywhere.
