A clear, practical step-by-step guide to safely download, install, and perform the first setup of Trezor Suite — the desktop application used to manage your Trezor hardware wallet. This guide covers preparation, download sources, installation steps for major platforms, first-run setup, and security best practices.
Why use Trezor Suite?
Trezor Suite is the official desktop app produced by SatoshiLabs for managing Trezor hardware wallets, viewing balances, sending transactions, and managing crypto accounts and settings. Using the official Suite (instead of third-party interfaces) reduces risk and provides a user-friendly experience with features like transaction history, coin management, and firmware updates.
Before you begin — preparation & safety checklist
Only download Trezor Suite from the official Trezor website or official app stores. Do not use links from unverified sources or social media posts.
Disconnect the device from any computer or network before beginning the installation process.
Have a pen and paper ready for your recovery seed if you’re initializing a new device — never store the seed digitally or share it online.
Make sure your operating system is reasonably up to date and that you have administrative rights to install software.
Close other browser windows / apps that you won't need; this reduces distractions and risk during setup.
Step 1 — Download Trezor Suite
Visit the official Trezor website from a trusted browser and look for the “Get Suite” or “Download Trezor Suite” link. Official installers are available for Windows, macOS, and Linux. If you prefer, Trezor also provides a web-based interface — the desktop app offers a local experience and slightly different feature set.
Tip: verify the web address in your browser carefully to ensure you are on the official site before downloading any installer.
If you see multiple download options: choose the installer that matches your operating system (Windows .exe/.msi, macOS .dmg/Apple Silicon build, or Linux AppImage/DEB/RPM depending on your distribution).
Step 2 — Verify the download (recommended)
Where possible, verify the file integrity. The Trezor team provides checksums and sometimes signatures for their releases. Verifying ensures the installer you downloaded hasn’t been tampered with.
Locate the checksum (SHA256) on the official download page or release notes.
On Windows, use PowerShell: Get-FileHash -Algorithm SHA256 "C:\path\to\file".
On macOS or Linux, use the terminal: shasum -a 256 /path/to/file or sha256sum /path/to/file.
Compare the computed checksum to the one published on the official site; they must match exactly.
Step 3 — Install Trezor Suite
Windows
Double-click the downloaded .exe or .msi file.
Follow the installer prompts. If Windows shows a security warning for unrecognized apps, confirm you downloaded the file from the official source before proceeding.
Grant permissions when prompted; after installation, launch Trezor Suite from the Start menu.
macOS
Open the downloaded .dmg and drag the Trezor Suite app to your Applications folder.
First run: macOS may warn the app is from an unidentified developer. Confirm the app in System Preferences → Security & Privacy if necessary.
Open the app from Applications (right-click → Open if macOS blocks it on first run).
Linux
Linux distributions may offer multiple formats. The AppImage is commonly usable across distributions; DEB/RPM are for Debian/Ubuntu or Fedora/RHEL families respectively.
Make AppImage executable:
chmod +x trezor-suite-*.AppImage
Run it:
./trezor-suite-*.AppImage
Or install DEB/RPM with your distribution package manager per the download instructions.
Step 4 — Initial setup & connecting your Trezor device
Launch Trezor Suite. You will be prompted to connect your Trezor hardware device using the supplied USB cable.
Only connect the device when prompted. Trezor devices show a physical confirmation screen — read it carefully and confirm any prompts on the device itself.
If your device is new: you'll be guided to create a new wallet and a recovery seed. Write down the seed on paper and store it securely offline.
If your device was previously set up: choose the appropriate option to unlock with your PIN or recover using your seed (again: never enter your seed into a computer or a website).
Follow any firmware update prompts shown by Trezor Suite. Firmware updates are signed and should be applied when offered; the Suite will guide you through a safe update process.
Security best practices
Never share your recovery seed. No legitimate support agent or service will ever ask for it.
Keep your recovery seed offline and stored in multiple secure locations if needed (e.g., a physically secure safe). Consider using metal backups for fire/water resistance.
Use a strong PIN on your Trezor device to protect against physical theft attempts.
Always verify addresses on the Trezor device screen before approving transactions — the device's display is the ultimate source of truth.
Be cautious of phishing websites or fake Suite downloads. Only use the official app and official documentation for guidance.
Troubleshooting common issues
If Trezor Suite does not detect your device:
Try a different USB port or a different, power-capable cable.
Ensure no other wallet software or browser extensions are actively accessing the device at the same time.
Restart the Suite and, if necessary, reboot your computer.
Make sure your operating system has the latest updates and drivers. On Linux, check udev rules if the device isn't detected.
After setup — daily use tips
Keep Trezor Suite up to date; updates often include security improvements and bug fixes.
Consider using the Suite for routine checks, but rely on the device screen to verify any critical action you approve.
Back up your recovery seed securely and review your backup plan periodically.
