Trézor Bridge is the secure communication layer that allows your hardware wallet to interact with your desktop environment. Essential for Trezor Suite & advanced crypto operations.
Trézor Bridge is a lightweight background service that securely links your **Trezor hardware wallet** with applications such as **Trezor Suite** on Windows, macOS, and Linux. Without this, your computer cannot properly recognize or communicate with the wallet device.
The role of the Bridge is similar to a translator: it ensures that your wallet and your crypto management software can exchange commands safely. It prevents unauthorized software or websites from interfering with device operations, ensuring **maximum security** during crypto transactions.  
It uses cryptographic validation, WebUSB or HID interfaces, device session authorization prompts, and handshake protocols that protect your private keys. Since **Keys never leave the wallet**, the Bridge acts purely as a communication relay — never storing or exposing sensitive data.
