Trezor Bridge®: Secure Web Integration for Your Hardware Wallet
Trezor Bridge® is a lightweight communication tool designed to connect your Trezor® hardware wallet securely with web browser-based interfaces. It acts as a vital translator, enabling your offline device to interact safely with third-party web applications like MetaMask, MyEtherWallet, or DeFi platforms – without ever exposing your private keys.
Understanding When Trezor Bridge® is Essential:
- Not for Trezor Suite®: If you primarily use the official Trezor Suite (desktop/web/mobile), Bridge is not required. Suite communicates directly with your device.
- Essential for Web Wallets: Bridge is mandatory when you need to use your Trezor® device (Model T or Safe 3) with:
- Browser extensions (e.g., MetaMask).
- Web-based wallets (e.g., MyEtherWallet, MyCrypto).
- Decentralized Applications (DeFi, DEXs, NFT platforms) accessed via your browser.
How Trezor Bridge® Works: Security First
- Silent Background Service: Once installed, Bridge runs unobtrusively in the background on your computer.
- Secure Channel Creation: When you connect your Trezor® to a supported web interface, Bridge establishes an encrypted communication channel between your browser and the physical device.
- Relay, Not Access: Bridge relays transaction signing requests to your Trezor® and signed responses back to the browser. Crucially:
- It never sees or accesses your private keys or Recovery Seed.
- It cannot initiate transactions itself.
- Physical Verification Maintained: All critical actions (confirming transactions, revealing public addresses) still require physical verification and approval on your Trezor® device's screen. Bridge doesn't bypass the core security model.
Key Features & Clarifications:
- No "Trezor Bridge Login": Bridge itself does not have a login interface. It facilitates the connection for other web services. Your security relies on your Trezor® device PIN and physical confirmation.
- Cross-Platform: Available for Windows, macOS, and Linux.
- Lightweight: Minimal system resource usage.
- Automatic Updates: Ensures compatibility and security.
Getting & Installing Trezor Bridge®:
- Visit the Official Source: Always download Bridge from the official Trezor site: Download Trezor Bridge.
- Install: Run the installer and follow the simple on-screen instructions.
- Restart Browser: Close and reopen your web browser after installation.
- Connect Trezor®: Plug in your Trezor® device, enter your PIN on the device, and navigate to the supported web wallet (e.g., MetaMask). Bridge should automatically enable the connection.

Trezor Bridge® FAQ: Solving Common Queries
-
Q: Do I need Trezor Bridge if I only use Trezor Suite?
A: No. Trezor Suite communicates directly with your device. Bridge is ONLY required for connecting your Trezor® to third-party web applications like MetaMask or MyEtherWallet. -
Q: How do I "log in" to Trezor Bridge?
A: There is no Trezor Bridge login screen. Bridge runs silently. "Login" means: 1) Install Bridge, 2) Connect Trezor® & enter PIN on device, 3) Access a supported web wallet. Bridge enables the connection; you authenticate via your Trezor® device. -
Q: Is Trezor Bridge safe? Can it steal my keys?
A: Bridge is open-source and developed by SatoshiLabs (Trezor's makers). Its design ensures it never accesses your private keys or Recovery Seed. It only passes encrypted messages between your browser and Trezor® device. Physical device confirmation remains mandatory. -
Q: Why isn't my Trezor® recognized by MetaMask/MyEtherWallet?
A: 1) Ensure Trezor Bridge is installed & running. 2) Restart your browser after installing Bridge. 3) Try a different USB cable/port. 4) Close Trezor Suite if open. 5) Check the specific web wallet's connection guide on Trezor Support. -
Q: Does Trezor Bridge work on mobile?
A: No. Trezor Bridge is for desktop browsers (Windows, macOS, Linux). To use Trezor® with web apps on mobile, you typically need a compatible mobile browser and often a special OTG cable/adapter, but Bridge itself isn't used. The Trezor Suite app (Android) is the primary mobile solution. -
Q: How do I update Trezor Bridge?
A: New versions are included with Trezor Suite updates. You can also download the latest version directly from the official Download Trezor Bridge page. Uninstall the old version first if prompted.
