What Is Trezor Bridge?
Trezor Bridge is a lightweight desktop background service that securely connects your Trezor hardware wallet to your web browser. Acting as a middleware, it ensures encrypted communication between your device and your crypto interface—so your private keys never touch your computer.
Why It Matters
-
Browser compatibility: It replaces deprecated browser extensions, working seamlessly across Chrome, Firefox, Brave, and others.
-
Security-first design: All operations—such as signing transactions—are confirmed on the Trezor device itself to fend off MITM attacks.
Installing & Using
-
Download the latest Bridge installer for your OS (Windows/macOS/Linux).
-
Run it; the service launches quietly in the background.
-
Connect your Trezor via USB. Open Trezor Suite or a browser wallet—Bridge auto‑detects the device.
How to Log In
-
Open your wallet interface.
-
Click Connect Trezor or similar.
-
Authenticate by entering your PIN directly on your device.
-
If prompted, approve address or transaction details—always verify on the hardware screen.
How to Log Out / Disconnect
-
In Trezor Suite or browser wallet, select Disconnect or close the session.
-
Optionally, unplug your device.
-
To fully stop Bridge, quit Trezor Suite or use your OS’s system tray to exit the Bridge process.
Pro Tips & Troubleshooting
-
If your browser won’t detect the device, try reinstalling Bridge or restarting the browser.
-
Download only from the official Trezor site to avoid imposters.
-
On browsers like Firefox, Bridge is often required even if Trezor Suite is running.
