01 / THE BASICS
A small bridge.
A direct connection.
Trezor Bridge is a background application that allows a compatible browser to communicate with a Trezor hardware wallet over USB. It acts as a messenger between the wallet and supported web interfaces, so the browser can request an action and the device can display it for you to review.
Your private keys remain on the hardware wallet. Bridge does not replace the device or authorize transactions on its own; you verify and approve sensitive actions on the wallet itself.

Review transaction details on the hardware wallet and confirm them there—not in a pop-up.
02Browser compatibility
Bridge is used by supported browser-based wallet experiences. Requirements can vary by operating system and browser.
03Easy device access
Once installed and running, Bridge can help a supported interface detect your USB-connected Trezor.
0402 / GET CONNECTED
Setup, without
the guesswork.
Use the official Trezor site to get the right software for your device. Never install wallet utilities from ads, unsolicited messages, or unfamiliar download sites.
01
Start at the official source
Open trezor.io/trezor-suite directly. Check the address carefully before downloading anything.
02
Install or update
Follow Trezor’s current instructions for your operating system. Install Bridge only if the official setup flow requests it; restart your browser if prompted.
03
Connect and unlock
Use a data-capable USB cable, connect your device, and unlock it using its on-device process. Open a compatible wallet interface.
04
Review on the device
When asked, inspect each address and transaction on the hardware wallet screen. Approve only details you recognize and intend.
Connection established on your terms.Your device remains the place to verify and approve sensitive actions.
Official help ↗03 / STAY IN CONTROL
Security is a
shared practice.
Bridge supports communication; it is not a substitute for careful verification. Treat your recovery information as the keys to your wallet.

04 / WHEN THINGS GO WRONG
Not connecting?
A few simple checks can resolve common connection issues.
Check the cable and port
Some USB cables only charge. Try a known data cable and another port, connecting directly rather than through a hub.
Restart the connection
Unlock the device, close and reopen the browser, then reconnect. Confirm Bridge is installed and running if your interface needs it.
Check for updates
Use official Trezor guidance to check your browser, Trezor Suite, firmware, and Bridge version. Avoid unofficial update links.

Good questions.
Clear answers.
Bridge requirements may change as browsers and Trezor software evolve. Check official documentation for the latest compatibility details.
Do I always need Trezor Bridge?+
Not necessarily. Trezor Suite and supported browser experiences may use different communication methods depending on platform and current software. Follow the official setup instructions shown for your device.
Does Bridge store my private keys?+
Bridge is a communication layer, not a place to store your wallet keys. Private keys are designed to remain on the hardware wallet. Confirm sensitive actions on the device screen.
Is Trezor Bridge the same as Trezor Suite?+
No. Trezor Suite is a wallet application; Bridge is a background communication component that may help supported browser interfaces connect to a device.
How do I update Bridge safely?+
Use Trezor’s official website or the update path provided by official Trezor software. Do not follow download links from unsolicited emails, search ads, or direct messages.
What if my browser still cannot find the wallet?+
Try a data-capable USB cable, reconnect the device, restart the browser, and verify any required Bridge service is running. If it persists, consult official support for your operating system.
