Secure Crypto Management Made Simple
Trezor Bridge is an essential component for Trezor hardware wallet users who need to connect their devices to web browsers. Modern browsers don't allow web pages to communicate directly with USB-connected hardware for security reasons, which is where Trezor Bridge comes in—it runs in the background on your computer and securely passes data between your browser, Trezor device, and Trezor's web services :cite[2].
The software is developed and maintained by SatoshiLabs, the creators of Trezor, and is open-source and regularly audited for security. It's important to always download Trezor Bridge only from the official website to avoid potential security risks :cite[2].
While Trezor Suite desktop app users typically don't need Trezor Bridge as the Suite handles communication directly, it remains essential for those using browser-based wallet interfaces like wallet.trezor.io or decentralized applications (DApps) that connect to Trezor devices :cite[2].
Trezor Bridge supports a secure cryptocurrency experience by enabling you to manage assets, send and receive coins, and interact with Web3 applications while keeping your private keys protected within your hardware wallet at all times :cite[1]:cite[6]. This approach maintains the fundamental security principle of hardware wallets: keeping private keys offline and away from potentially vulnerable internet-connected devices :cite[6].
Installation is straightforward: visit the official Trezor Bridge download page, choose your operating system (Windows, macOS, or Linux), download and install the software, then restart your browser. Once installed, Trezor Bridge runs quietly in the background, enabling secure communication between your browser and Trezor device :cite[2].
