What is Trezor Bridge?
Trezor Bridge is a background communication utility developed by SatoshiLabs that enables web browsers to securely interact with Trezor® hardware wallets. It acts as a translator between web applications and your physical Trezor® device, facilitating the Trezor Bridge Login process without compromising security.
Unlike browser extensions that operate within the browser environment, Trezor Bridge runs as a separate system service, providing an additional layer of security by isolating the communication channel between your Trezor® device and web-based applications like the Trezor Suite web interface.
Connection Bridge
Creates a secure communication channel between web browsers and your Trezor® hardware wallet, enabling seamless interaction while maintaining security protocols.
Security Layer
Operates as a system-level service rather than a browser extension, reducing attack surface and preventing browser-based vulnerabilities from affecting device communication.
Automatic Operation
Works silently in the background, automatically activating when needed for Trezor Bridge Login processes without requiring manual intervention.

Frequently Asked Questions
Yes, Trezor Bridge is completely safe when downloaded from the official Trezor website. It's open-source software that has been thoroughly audited for security. The Bridge only facilitates communication between your browser and Trezor® device—it cannot access your private keys, recovery seed, or initiate transactions without your explicit approval on the device itself.
No, if you're using the desktop version of Trezor Suite (installed via Trezor Suite download), you do not need Trezor Bridge. The desktop application communicates directly with your Trezor® device without browser intermediation. Bridge is only required for web browser access to your Trezor Wallet.
Trezor Bridge runs as a background service to maintain a constant, ready state for communication between web browsers and your Trezor® device. This ensures that when you initiate a Trezor Bridge Login or need to confirm a transaction, the connection is immediately available without delays for service startup.
No, the Trezor Suite app for mobile devices does not require Trezor Bridge. Mobile devices connect directly to Trezor® hardware wallets using OTG (Android) or lightning cables (iOS). Bridge is specifically designed for desktop browser communication and serves no purpose on mobile platforms.
First, try restarting the Bridge service from your system tray or applications menu. If that doesn't work, restart your computer and browser. For persistent issues, reinstall Bridge from the official website. As a temporary workaround, you can use the desktop version of Trezor Suite which doesn't require Bridge.
