A concise presentation-style guide explaining Trezor Bridge, installation, troubleshooting, and best security practices for connecting a Trezor hardware wallet to your computer or browser.
Trezor Bridge is a small, secure background application that enables communication between your Trezor hardware device and web-based wallets or Trezor Suite. It replaces direct browser USB access with a trusted local bridge so browsers and web apps can interact with the hardware wallet safely.
Using Bridge ensures stable cross-browser connectivity and isolates USB traffic so that browser sandboxing and security checks remain intact. For most users, installing Bridge is the simplest way to get started with Trezor without changing browser settings or relying on deprecated protocols.
Trezor Bridge is available for Windows, macOS, and Linux. Choose the installer matching your operating system and follow the installer prompts. On some Linux distributions a package or snap may be available.
Always download Bridge from official sources and avoid third-party mirrors. After installation, verify the connection using the wallet’s status indicator before performing sensitive actions.
Use the Bridge log files (found in the OS-specific application data folder) when contacting support. Logs help engineers identify driver, permission, or hardware-level issues faster.
Always use official downloads and check checksums/signatures where available. Keep your Trezor firmware up to date through official channels to benefit from security patches and improvements.
Connect your Trezor only when needed, avoid using unknown public networks for critical transactions, and never enter your recovery seed into any software or web page. Bridge only relays device communication — seed security remains your responsibility.
Trezor Suite is the official desktop application that integrates with Bridge but can also work standalone. It offers a more controlled environment for managing firmware, accounts, and backups.
Third-party web wallets provide convenience and UI features but may require Bridge for secure USB communication. Prefer well-known, audited wallets and enable additional protections like hardware wallet confirmations for critical transactions.
