Using Trezor Bridge is simple and intuitive. Here's everything you need to know.
Simply plug your Trezor device into your computer via USB. The Bridge will automatically detect it within seconds. You'll see a notification confirming the connection. Make sure to use the official Trezor USB cable for best results.
If you're connecting for the first time, your operating system may take a moment to install the necessary USB drivers. This is normal and only happens once. The green light on your Trezor will indicate it's ready to use.
Open your preferred web browser and navigate to Trezor Suite or any compatible web wallet. The Bridge establishes a secure connection automatically, allowing the web application to communicate with your device without any additional steps.
You can use multiple browser tabs simultaneously, and the Bridge will manage all connections efficiently. Each application will need to be authorized on your Trezor device's screen before it can access your wallet data.
When you initiate a transaction, the Bridge securely transmits the transaction details to your Trezor device. Review all information carefully on your device's screen - including the recipient address, amount, and fees.
Press the physical button on your Trezor to confirm. The Bridge then sends the signed transaction back to the web application for broadcasting. Your private keys never leave the device, ensuring maximum security.
When you're done, simply close your browser tabs and unplug your Trezor device. The Bridge will automatically close the secure connection. There's no need to manually stop or exit the Bridge application - it continues running in the background.
The Bridge uses minimal resources when idle and will be ready for your next session. You can check its status at any time through the system tray icon (Windows/Linux) or menu bar (macOS).

Maximize your security by following these essential guidelines
Only download Trezor Bridge from the official Trezor website (trezor.io) or verified GitHub repository. Never download from third-party sites, as they may contain malware or compromised versions. Verify the digital signature of the installer before running it.
Always verify transaction details on your Trezor's physical screen before confirming. Never trust what you see on your computer screen alone. If the addresses or amounts don't match, reject the transaction immediately and investigate for potential malware.
Regularly update Trezor Bridge to ensure you have the latest security patches and bug fixes. Enable automatic updates if available. Also keep your Trezor firmware, operating system, and browsers up to date to maintain comprehensive security across your entire setup.
Avoid using public Wi-Fi networks when accessing your cryptocurrency wallets. If you must use public networks, use a reputable VPN service. Your home or office network with a properly configured firewall is the safest option for managing your crypto assets.
Keep your computer secure with updated antivirus software, regular security scans, and strong passwords. Enable full disk encryption, use a firewall, and be cautious about installing software from unknown sources. A compromised computer can lead to security risks even with a hardware wallet.
Store your recovery seed securely offline in multiple locations. Never enter your seed into any computer or phone, and never take photos of it. Consider using metal backup solutions for fire and water resistance. Your seed is the ultimate backup - protect it like your life depends on it.
Get answers to the most common questions about Trezor Bridge
Yes, Trezor Bridge is essential for using your Trezor with web-based applications like Trezor Suite. It replaced the older browser extension method and provides a more secure, reliable connection. Without the Bridge, modern web browsers cannot communicate with your Trezor device. However, you can use Trezor Suite as a desktop application without the Bridge, though the web version is recommended for its ease of use and automatic updates.
Trezor Bridge is completely safe and cannot access your private keys. It only facilitates communication between your web browser and Trezor device. Your private keys always remain securely stored in your Trezor's isolated environment and never leave the device. The Bridge simply passes encrypted messages back and forth. All transaction signing happens inside the Trezor hardware, which is mathematically impossible to hack. The Bridge's source code is open-source and regularly audited by security experts.
Trezor Bridge works with all major modern browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, Brave, Opera, and Vivaldi. It also works with Chromium-based browsers like the new Edge. The Bridge operates at the system level, so browser compatibility is generally not an issue. However, you'll need a relatively recent browser version (released within the last 2-3 years) for optimal compatibility with Trezor Suite and other web wallets.
No, Trezor Bridge is extremely lightweight and uses minimal system resources. It typically consumes less than 10MB of RAM and negligible CPU when idle. Even during active use, the resource usage remains very low. The Bridge is designed to run silently in the background without impacting system performance. You won't notice any slowdown even on older computers. It starts quickly and doesn't interfere with other applications or services running on your system.
Yes, absolutely! Trezor Bridge can manage multiple Trezor devices simultaneously. You can have multiple devices connected at the same time, and web applications will detect all of them. This is useful if you manage multiple wallets or use different Trezor models. The Bridge handles all connections efficiently without requiring separate installations or configurations. Just plug in your devices and they'll all be accessible through your web browser.
The easiest way is to visit Trezor Suite - if your Bridge is outdated, you'll see a notification prompting you to update. You can also check the Bridge version by visiting localhost:21325 in your web browser, which will display version information and status. Trezor Bridge typically checks for updates automatically and may prompt you to install new versions. You can also manually download the latest version from the official Trezor website at any time. Keeping your Bridge updated ensures compatibility with the latest Trezor firmware and web applications.
Some antivirus programs may flag Trezor Bridge as suspicious because it opens a local network port (21325) for communication. This is a false positive. Trezor Bridge is digitally signed by SatoshiLabs and is completely safe. You can verify the digital signature before installation. To resolve this, add Trezor Bridge to your antivirus's whitelist or exclusion list. Make sure you downloaded the Bridge from the official Trezor website. If you're still concerned, you can review the open-source code on GitHub or contact your antivirus vendor to report the false positive.
Yes, but with some considerations. You'll need to ensure that USB passthrough is properly configured in your virtualization software (VMware, VirtualBox, Parallels, etc.) so the Trezor device is accessible to the virtual machine. Install the Bridge inside the VM as you would on a physical machine. Performance should be identical to a native installation. However, for maximum security, it's generally recommended to use Trezor on a physical machine rather than a VM, especially if you're storing significant amounts of cryptocurrency. VMs can introduce additional attack vectors depending on your configuration.
