THE CONNECTION, SIMPLIFIEDSCROLL TO EXPLORE ↓
01 / THE BASICS
What is Trezor Bridge?
Trezor Bridge is a small background application that enables supported web browsers to communicate with a Trezor hardware wallet connected to your computer. Think of it as a translator: it carries requests between the wallet interface in your browser and your physical device.
The Bridge runs on your computer rather than inside the browser tab. When a compatible wallet service needs to check the device or request an action, Bridge helps pass that communication along. The wallet itself remains the place where you review and confirm sensitive operations.
It is not a wallet, an account, or a place where you store recovery information. You do not need to enter your recovery seed into Bridge or a website to make a connection.
02 / CONNECTION FLOW
A small bridge.
A clear connection.
Your browser, Bridge, and hardware wallet each have a distinct role. Together, they let a compatible interface recognize your connected device and send requests for your review.

Hardware wallet
Your device displays prompts for you to verify.
✓ A detected device is not the same as an approved action. Always verify details on the wallet screen.
03 / MADE TO WORK TOGETHER
Good communication
makes things simple.
Bridge supports the handoff—not the decisions. Here are the practical benefits of having the right connection layer in place.
Browser compatibility
Works as part of the supported software setup for your operating system and wallet interface.
Check compatibility ↗Security-minded flow
Important actions still require attention on the physical wallet. Bridge does not replace device verification.
Security practices ↗Steady communication
Keeping software current and avoiding conflicting wallet tools can reduce connection interruptions.
Update guidance ↗04 / GET STARTED
Set up the connection
in a few steps.
Exact screens can vary by computer and software version. Use official Trezor resources for current downloads and compatibility details.
Visit Trezor Suite Opens the official Trezor website in a new tab.- 01✓
Check your starting point
Use a supported operating system and browser. Close other wallet applications that may be trying to access the device.
- 02↓
Get Bridge from an official source
Visit Trezor’s official website and follow its current Bridge installation instructions. Avoid download links from ads or unsolicited messages.
- 03⟳
Install and restart if needed
Run the installer for your operating system. Follow on-screen prompts; a browser restart or computer restart may help the browser find the new service.
- 04✓
Connect and check your device
Connect the wallet directly with a data-capable USB cable, unlock it, then open a compatible wallet interface and choose the device when prompted.
05 / DEVICE DETECTION
Is your device
showing up?
A successful connection usually begins with a direct USB connection and an unlocked device. Your browser may ask for permission to access it; select the intended wallet and follow the prompt on the physical screen.
Recognition can depend on the cable, USB port, browser permissions, operating system, and whether another application already has access. If the interface does not see the device, work through these checks before reinstalling software.
01
Use a known data cableSome USB cables provide power only.
✓02
Try another portConnect directly rather than through a hub.
✓03
Unlock the walletKeep the device awake during connection.
✓04
Review browser accessAllow access only for a service you trust.
✓06 / SECURITY NOTICE
Keep the final check
in your hands.
Bridge is a communication utility, not a security guarantee. Only install software from a source you have independently verified. Never share your recovery seed, and never type it into a browser, support chat, or Bridge installer. Confirm addresses and transaction details on your hardware wallet before approving anything.

07 / QUICK TROUBLESHOOTING
When the connection
needs a nudge.
Try one change at a time. This makes it easier to spot what helped.
Nothing appears
Check that the cable supports data, unlock the device, then test a different USB port. Refresh the wallet interface after reconnecting.
Bridge seems unavailable
Confirm Bridge is installed and running, then restart the browser. If needed, use the official installation instructions to repair or update it.
Another app has control
Close other wallet tabs or applications, disconnect the device, and reconnect it. A single app may need exclusive access to the USB device.
08 / KEEP IT CURRENT
Updates are part
of a healthy setup.
Software updates can improve compatibility and resolve known issues. Check Trezor’s official site periodically for current Bridge releases and supported browser or operating-system versions. Download updates directly from trusted official pages, and be cautious of unsolicited “urgent update” messages.
After updating, reconnect your device and verify that the wallet interface detects it before continuing. If you are troubleshooting, note your operating system and software version so you can find relevant official guidance.
09 / SMALL THINGS THAT HELP
Make every
connection count.
- ↗ Bookmark official support and download pages instead of following search ads.
- ⌑ Keep your hardware wallet firmware and companion software current using official guidance.
- ◉ Do not connect your wallet to unfamiliar sites just to “test” Bridge.
- ✓ If anything looks unexpected, cancel on the device and verify the service before retrying.
