Guidance: Installing and Using Trezor Bridge
Trezor Bridge enables secure communication between your Trezor device and supported software. Start by using the official download link or the distribution recommended by the vendor. After downloading the installer, run it with administrator privileges if required, and follow the on-screen prompts. When installation completes, your system will register a local service that listens for the device. If you prefer, you can consult the official documentation before installing — see the installation notes.
Once installed, connect your Trezor hardware to a USB port. Modern Trezor devices use standard USB interfaces and should power up automatically. Open your wallet application or a supported web interface that integrates with Trezor. The first connection often triggers a browser prompt asking for permission to access the device; grant permission only when you initiated the session. If a browser fails to detect the device, confirm the bridge service is running and check any prompt or permission dialog in the system tray or notification area. If necessary, restart the browser or the bridge service, and try the connection again. See the troubleshooting guide for common fixes.
Security considerations are paramount. Never install software or updates from untrusted sources. Always confirm the digital signatures or checksums published by the vendor where available. When connecting your Trezor, verify the device's screens and prompts match expected text; do not proceed if unexpected messages appear. If a webpage asks for your recovery seed or private key details, close the page immediately and report the incident. Legitimate software will never request your seed. For additional details, consult the vendor's security notes and the community support forums.
Browser compatibility: Most modern browsers work with Trezor Bridge, but behavior differs slightly across Chromium-based browsers, Firefox and others. Some browsers may require extra configuration or an extension. If the wallet web app prompts you to switch transport methods, follow the recommended approach for your browser and operating system. If you encounter persistent detection issues, try an alternative browser or update the browser to the latest stable release. You can find browser-specific tips in the compatibility section of the docs.
Firmware and software updates: Keep your Trezor firmware and Bridge software up to date. Updates often include security enhancements and improved compatibility. Back up your recovery seed securely before performing firmware upgrades. If you need step-by-step instructions for updating firmware, check the official update walkthrough linked from the vendor site or the app's update panel.
Troubleshooting: If the bridge app fails to start, check system logs for errors, ensure no other USB management tools are blocking access, and temporarily disable strict antivirus or sandboxing tools while testing. Reinstalling the bridge or rebooting the host system often resolves transient connectivity problems. For persistent hardware faults, test the Trezor device on another machine to isolate the issue.
Best practices summary: install only from trusted sources, keep software and firmware updated, verify on-device prompts, never share your seed, and consult official help resources when in doubt. Use hardware wallets in combination with secure host practices for the strongest protection.
