The **Trezor® Bridge** is legacy software that enables communication between your browser and your **Trezor® Hardware Wallet**, crucial for the old **Trezor® Wallet Login** process.
The **Trezor® Bridge** is a small, background application designed to facilitate communication. When using the legacy web **Trezor® Wallet**, your browser cannot directly "see" your **Trezor® Hardware Wallet**. The Bridge serves as the essential middleman, allowing your computer to recognize the device.
This communication is vital for processes like the initial device setup (often initiated via **trezor.io/start**), the **Trezor® Wallet Login**, and, most importantly, signing transactions. If you are experiencing connection issues when trying to sign a transaction, an outdated or missing **Trezor® Bridge Download** might be the culprit.
**Note:** If you are using the modern, dedicated **Trezor® Suite** (desktop or the **Trezor® Suite App**), you typically do **not** need the Bridge, as the Suite handles connectivity natively.
The Bridge creates a secure communication channel (a local WebSockets server) between the operating system, the USB-connected **Trezor® Hardware Wallet**, and the Trezor web interface. Without a valid **Trezor® Bridge Download** installation, web-based interaction is impossible.
Always ensure you get the **Trezor® Bridge Download** directly from the official Trezor® source, linked from **trezor.io/start**, to avoid compromised versions. Your device keys are still protected by your **Trezor® Login** PIN.
While the **Trezor® Bridge Download** serves a necessary function for the old web interface, Trezor® strongly recommends migrating to the **Trezor® Suite**. The Suite offers a unified platform for your **Trezor® Wallet** and eliminates the dependency on the separate Bridge component.
If you must use the Bridge, access the verified downloads below. Remember, the **Trezor® Suite Download** includes better features and a smoother experience.
