How Trezor.io/Start Works with Trezor Bridge

When you visit . to set up your Trezor hardware wallet, one of the key tools that powers the connection between your device and your computer—especially in browser environments—is Trezor Bridge.

Here’s how they work together:

What Is Trezor.io/Start?

Trezor.io/Start is the official setup portal where users are guided to:

• Choose their Trezor model (Model One or Model T)
• Download Trezor Suite (the desktop app)
• Learn how to install firmware, back up the recovery seed, and start using their wallet securely

However, in some cases—especially when users interact with browser-based tools or third-party web apps—Trezor Bridge is required.

What Is Trezor Bridge?

Trezor Bridge is a background software that allows your browser to communicate securely with your Trezor hardware wallet. It runs quietly on your computer and acts as a communication channel between the web interface and the physical device.

You’ll often need Bridge if you’re:

• Using the Trezor Web Suite (web version of Trezor Suite)
• Interfacing with third-party apps or wallets that connect via browser
• Not using the Trezor Suite desktop app

How They Work Together

Here’s a step-by-step outline of how Trezor.io/Start and Bridge interact during setup:

1. User Goes to Trezor.io/Start

• The user opens a browser and visits.
• The page detects the device and browser environment.

2. Site Checks for Bridge

• If the browser does not have a native connection to the Trezor device, the website will prompt the user to install Trezor Bridge.
• This is typically required for browsers like Chrome or Firefox to securely interact with USB-connected hardware wallets.

3. User Installs Bridge (If Needed)

• The user is redirected to download Trezor Bridge from the official source.
• Once installed, the service runs in the background and allows communication between the Trezor device and browser.

4. Secure Communication Begins

• With Bridge running, the browser can detect the Trezor device.
• The user can proceed with setting up the device, installing firmware, and generating a recovery seed—all with confirmations displayed on the physical Trezor.

5. Option to Use Trezor Suite

• Trezor.io/Start recommends installing Trezor Suite Desktop, which does not require Bridge, as it handles device communication natively.
• However, for users who prefer or need to use the web version (suite.trezor.io/web), Bridge is essential.

Do You Always Need Trezor Bridge?

• No, if you use the Trezor Suite desktop app, Bridge is not required.
• Yes, if you are using the web interface or connecting your Trezor to third-party wallets via browser.

Security Note

• Always download Trezor Bridge from the official website only: https://trezor.io/bridge
• Never install extensions or apps that claim to be “Trezor connectors” unless directly linked from Trezor.io

Conclusion

Trezor.io/Start provides the onboarding and setup experience for your Trezor device. When using a browser, it works in tandem with Trezor Bridge, which acts as the secure link between your Trezor and the web interface. While Trezor Suite desktop is the recommended method (which doesn’t require Bridge), Bridge remains an essential tool for browser-based crypto management.
