SECURITY FIRST
Trezor devices ship without firmware for security reasons. Never use a device that arrives with firmware pre-installed or a pre-written recovery seed. A genuine device will always prompt you to install firmware during setup.
Preparation Checklist
Device
Trezor Safe 3, Model T, or Model One (legacy models remain supported).
Cable
USB-C (Safe 3 / Model T) or Micro-USB (Model One) for secure connection.
Backup Tools
Provided card and pen for writing down your wallet recovery seed words.
Computer
Windows, macOS, or Linux with Trezor Suite installed for initialization.
Setup Process
1
Download Trezor Suite
Visit trezor.io/start and click 'Download for desktop'. This is the official gateway for Trezor Suite, the secure desktop application for managing your device.
2
Connect and Initialize
Plug your Trezor device into your computer using the appropriate cable. Open Trezor Suite and click 'Set up my Trezor' when the device is detected.
3
Install Firmware
Trezor Suite will prompt you to install the latest firmware. Choose between Standard or Bitcoin-only firmware. The device will restart automatically after installation.
4
Secure Authentication
A Secure Element authenticity check confirms the device was genuinely manufactured by Trezor and has not been altered. Follow the on-device confirmation steps.
5
Create or Recover Wallet
Select 'Create a new wallet' for a fresh setup, or 'Recover' if you are restoring from an existing backup. New wallets require agreeing to the Terms of Use on the device itself.
6
Write Down Your Backup
The device displays your recovery seed words one by one. Write them in exact order on the provided card. Never photograph, type into a computer, or store digitally.
7
Verify and Secure PIN
The device will ask you to confirm specific words from your backup to prove you wrote them down correctly. Choose a PIN of at least 4 digits (up to 50).
Wallet Creation & Backup
Create
Initiate the setup flow by selecting 'Create a new wallet' in Trezor Suite. This step requires you to agree to the Terms of Use on the device itself to establish your primary security anchor.
Backup
The device displays your recovery seed words one by one. Write them in exact order on the provided card. Never photograph, type into a computer, or store digitally. Newer Safe 3 devices may default to a 20-word backup; older cards use 12 or 24 words.
Verify
The device will ask you to confirm specific words from your backup to prove you wrote them down correctly. This verification step is critical to ensure your recovery path remains intact.
