Trezor Bridge® is the official desktop/HTTPS connection service developed by SatoshiLabs that allows your Trezor hardware wallet (e.g., Model T, One) to communicate securely with supported applications, including web browsers, desktop wallets, and other interfaces. :contentReference[oaicite:2]{index=2}
This tool replaces older browser plugins or legacy USB drivers by running locally on your computer as a trusted background service. :contentReference[oaicite:3]{index=3}
Without Bridge, many browsers and web apps will not detect your Trezor device, especially when advanced USB support isn’t available. :contentReference[oaicite:4]{index=4}
Modern browsers often limit direct USB access for security reasons. Trezor Bridge acts as a local mediator that bridges the connection in a controlled and secure way. :contentReference[oaicite:5]{index=5}
Bridge works on major operating systems — Windows, macOS, and Linux — and ensures that your hardware wallet functions the same across all platforms. :contentReference[oaicite:6]{index=6}
Bridge only exposes a local endpoint (e.g., localhost) — it does not transmit private keys or sensitive data to external servers. :contentReference[oaicite:7]{index=7}
Visit the official Trezor Bridge download page to get the installer for your operating system. :contentReference[oaicite:14]{index=14}
Run the downloaded setup file and follow on-screen instructions. After installation, Bridge runs as a background service. :contentReference[oaicite:15]{index=15}
Close and reopen your browser to ensure Bridge is recognized. Plug in your Trezor afterward to test connectivity. :contentReference[oaicite:16]{index=16}
If installation fails, try running the installer as Administrator or check your OS firewall settings. :contentReference[oaicite:17]{index=17}
Bridge listens on a localhost address by default and waits for compatible apps (like Trezor Suite or browser apps) to send requests. :contentReference[oaicite:18]{index=18}
The tool forwards commands from the app to the USB device securely and reliably, ensuring that private keys never leave the hardware wallet. :contentReference[oaicite:19]{index=19}
All transactions and sensitive actions must be manually confirmed on your Trezor device’s screen before they execute. :contentReference[oaicite:20]{index=20}
Never use unofficial or third-party installers — always use the official Trezor site. :contentReference[oaicite:21]{index=21}
When provided, check digital signatures or checksums to ensure integrity. :contentReference[oaicite:22]{index=22}
Regular updates fix bugs and improve security. Check for updates at the official resource pages. :contentReference[oaicite:23]{index=23}
Restart your browser or system. Ensure Bridge is running in the background. :contentReference[oaicite:24]{index=24}
Try another USB port/cable and confirm support in your OS USB settings. :contentReference[oaicite:25]{index=25}
Clear cache, disable conflicting extensions, or uninstall older Bridge versions before reinstalling. :contentReference[oaicite:26]{index=26}
If your browser doesn’t support required USB APIs, switch to a browser like Chrome/Edge during setup. :contentReference[oaicite:27]{index=27}
Sometimes desktop apps like Trezor Suite bundle Bridge, but for many web apps a standalone install is still necessary. :contentReference[oaicite:28]{index=28}
Yes — when downloaded from the official site, Bridge is secure and trusted. :contentReference[oaicite:29]{index=29}
