Welcome to the official guide: Trezor Bridge® | Starting Up Your Device®. In this detailed walkthrough, you will learn how to download, install, and configure the Trezor Bridge software for your hardware wallet device. The Bridge acts as a secure communication layer between your computer’s browser and your Trezor device, enabling safe transactions, firmware updates, and wallet management.
This content covers brand‑new explanations, step‑by‑step instructions, and fresh terminology suited for beginners and experienced users alike. Throughout, we’ll incorporate key phrases such as “Trezor Bridge installation,” “device connection,” and “secure firmware update.” Let’s begin your journey toward a safer cryptocurrency experience.
First, go to the official Trezor website and locate the Bridge download page. Choose the correct version for your operating system: Windows (64‑bit), macOS, or Linux. The downloaded file is typically named something like trezor‑bridge‑installer.exe or trezor‑bridge‑dmg. Always verify the digital signature or checksum to ensure authenticity.
Launch the installer. On Windows, you may see a User Account Control prompt—click “Yes” to allow. On macOS, you might need to drag the app into your Applications folder. On Linux, extract the tarball or install via package manager if available.
During installation, the Bridge may request permission to open firewall ports or allow local loopback communication. Grant the necessary permissions so that your browser can communicate with the Trezor hardware device. This is a one‑time setup and does not expose your system to external threats.
After installation, open a terminal or command prompt and run a command like trezor‑bridge --version. You should see a version number displayed. This confirms the Bridge is ready to run in the background. You may also notice a small system‑tray icon indicating the Bridge is active.
Plug in your Trezor via USB to your computer. Modern models support USB‑C or micro‑USB. Use a direct, high‑quality cable (do not use a power‑only cable without data lines). Your browser should detect the device via Bridge.
If it’s a new device, you will be guided through setting a PIN, writing down your recovery seed, and confirming random words. If you already have a recovery phrase, you can choose “Recover wallet” and input your seed (usually 12, 18 or 24 words) to restore your accounts.
Your PIN is the first line of defense. Use a non‑obvious combination and avoid reuse of frequently used digits. The PIN is never stored on Trezor; it’s only checked internally at runtime.
Always write your recovery seed on the official backup card or sheet. Never take a photo or store it digitally. If you lose both your device and seed, your funds are irrecoverable.
After initialization, your Trezor should show a welcome screen. In the browser, open Trezor Suite or connect via the web interface. You should see your accounts, balances, and ability to send/receive cryptocurrency. This confirms the Bridge is functioning.
Always use the latest version of Trezor Bridge, as updates may patch vulnerabilities, improve compatibility, or support new models. The software periodically checks for updates and will notify you when a newer version is available.
Only download Bridge from the official Trezor domain or GitHub repository, never from third‑party mirrors. Malicious or altered versions may compromise security.
Trezor Bridge runs entirely on your computer—not in the cloud—ensuring your private keys and communication stay local and encrypted. This is fundamental to maintaining a secure hardware wallet environment.
Bridge is compatible with Chrome, Firefox, Edge, and other modern browsers. If the browser does not detect the device, check that Bridge is running and not blocked by an extension or firewall.
If your device is not recognized, try the following: reconnect USB, reboot your computer, disable conflicting extensions, restart Bridge service, or reinstall the latest version. For persistent errors, consult the Trezor support pages.
Trezor Bridge is a background application that creates a secure connection between your Trezor hardware wallet and your web browser. Without Bridge, the browser cannot reliably detect or communicate with the Trezor device.
Yes. Bridge operates locally on your machine and does not send your private keys over the internet. It only relays encrypted commands between your browser and device. Always download it from the official Trezor site to ensure integrity.
Yes. You can connect multiple Trezor units (e.g. Trezor One, Trezor Model T) to the same computer. Bridge will manage communication as long as each device is recognized and not blocked by USB conflicts.
First check that Trezor Bridge is running. If not, restart the service or reinstall it. Also verify that firewall or antivirus software is not blocking the local bridge port (usually localhost). Try using a different USB port or cable.
Update Bridge whenever a new version is released or when you see a prompt in Trezor Suite or web UI. Keeping Bridge up to date ensures compatibility with browser updates and device firmware changes.
