The Trezor Bridge download process provides you with essential communication software that enables web browsers to interact securely with your Trezor® hardware wallet. This background service is crucial for users who prefer web-based interfaces or need to access third-party services that integrate with Trezor Wallet technology.
Unlike the desktop Trezor Suite application which has built-in device communication capabilities, web browsers require Trezor Bridge to facilitate the secure Trezor Bridge login process and enable transaction signing through browser-based applications.

Visit the official Trezor® website and navigate to the Bridge download section. Never download from third-party sources to avoid malware and security compromises.
Choose the correct version for your operating system. The website typically auto-detects your OS but allows manual selection for specific requirements.
Download the installer package and run it with administrator/sudo privileges. Follow the installation wizard through the standard setup process.
Completely close and restart your web browser after installation. This ensures the browser detects and integrates with the newly installed Bridge service.
Connect your Trezor® device and attempt a Trezor Bridge login on a supported web service to verify the installation was successful.
Only download Trezor Bridge from the official trezor.io website. Fake download sites may distribute malware that can compromise your device security. Always verify the digital signature when available.
The Bridge service runs as a localhost application (typically on port 21325) and only facilitates communication - it cannot access your private keys, recovery seed, or transaction data. All sensitive operations still require physical confirmation on your Trezor® device.
If you complete the trezor suite download and install the desktop application, you won't need Trezor Bridge for most operations. The desktop Suite includes built-in device communication capabilities.
Trezor Bridge download is essential for: Web-based wallet interfaces, third-party DeFi applications, NFT marketplaces, and any web service that requires direct Trezor Wallet integration. For new device setup, you'll still need to visit trezor.io/start regardless of Bridge installation.
Yes, when you complete the trezor suite download and install the desktop application, Trezor Bridge is typically installed automatically as part of the package. However, you can download Bridge separately if needed.
No, the trezor suite app for mobile devices uses native communication protocols (Bluetooth for Model T, USB-OTG for all models) and doesn't require or support Trezor Bridge.
Trezor Bridge login refers to the authentication process facilitated by Bridge for web applications, while regular Trezor login occurs in the desktop Suite. The security steps and PIN entry process remain identical.
Yes, once installed, Trezor Bridge works with all supported browsers on your system simultaneously. There's no need for separate installations for different browsers.
Trezor Bridge includes automatic update functionality. When new versions are available, you'll receive a notification and the update process typically requires just a few clicks to complete.
Try downloading again from the official website, ensure you have administrator privileges, temporarily disable antivirus software during installation, and verify your system meets all requirements. If issues persist, use the desktop Trezor Suite as an alternative.
