Trezor® Bridge: Your Secure Link Between Hardware & Web

Trezor® hardware wallets store private keys offline, providing unmatched security. But interacting with web-based tools requires a safe communication channel. Trezor® Bridge is the essential, lightweight software that enables this critical connection between your Trezor® device and your web browser, without compromising security.

What Trezor® Bridge Does (And Doesn't Do)

• Core Function: Acts as a secure translator, allowing your browser (Chrome, Firefox, Edge, etc.) to communicate with your physically connected Trezor® Model T or Safe 3. Browsers can't directly access USB devices securely; Bridge solves this.
• Maintains Security: Bridge only passes messages. It cannot access your private keys, recovery seed, or PIN. All sensitive operations happen solely on your Trezor® device.
• Silent Operator: Runs in the background after installation. No user interface or constant interaction needed.
• It is NOT:
  • A wallet (holds no keys or crypto).
  • Trezor® Suite (the main management interface).
  • A login portal ("Trezor Bridge Login" is a misnomer - explained below).

When Trezor® Bridge is Essential

You need Bridge only when using your Trezor® with web browser-based interfaces:

1. Trezor® Suite Web App: Accessing your wallet at suite.trezor.io.
2. Third-Party Web Wallets: Connecting your Trezor® to services like MetaMask (for hardware wallet linking), MyEtherWallet (MEW), or other DeFi/web3 platforms that support Trezor® hardware.
3. Initial Web Setup (Sometimes): The setup wizard at trezor.io/start may utilize Bridge if performing setup via browser.

When Trezor® Bridge is NOT Needed

• Using Trezor® Suite Desktop App: Downloaded from trezor.io/suite (Windows, macOS, Linux). The desktop app communicates directly via USB.
• Using Trezor® Suite Mobile App: Connects directly to your Android/iOS device via USB cable/adapter. No browser, no Bridge.

Installing Trezor® Bridge: Quick & Secure

1. Official Source ONLY: Always download from: https://trezor.io/bridge. Never use third-party sites.
2. Download & Install: Select your OS (Windows, macOS, Linux), run the installer, and follow simple prompts.
3. Runs Automatically: Bridge typically starts with your computer and runs in the background (check system tray/menu bar).
4. Restart Browser: Close and reopen your web browser after installation.

Debunking "Trezor Bridge Login"

• No Login Page Exists: Trezor® Bridge does not have a login interface, username, or password. Searching for "Trezor Bridge Login" often stems from confusion.
• The Real Login Happens on Device: When using Bridge (e.g., with Suite Web App):
  1. You connect your Trezor®.
  2. The web app detects it (via Bridge).
  3. You are prompted to enter your PIN.
  4. You enter your PIN DIRECTLY ON YOUR TREZOR® DEVICE'S SCREEN/BUTTONS.
  5. Bridge securely relays the confirmation that the correct PIN was entered on the device to the web app.
• Phishing Warning: Any website claiming to be a "Trezor Bridge Login" page is a scam. Never enter your PIN, seed, or any credentials on such a site. Legitimate PIN entry only occurs on your Trezor® hardware.

Troubleshooting Common Bridge Issues

If your Trezor® isn't detected in a web interface:

1. ✅ Confirm Bridge Installed/Running: Check via system tray/menu bar or trezor.io/bridge.
2. 🔄 Restart: Restart Bridge (if possible via its menu), restart your browser, reconnect Trezor®.
3. 🔌 Check Connections: Try a different USB port and cable.
4. 🌐 Browser Permissions: Ensure your browser has permission to access USB devices (check settings or prompts during first connect).
5. 🚫 Close Conflicting Software: Ensure Trezor® Suite Desktop or other wallet apps aren't using the device.
6. 🆕 Reinstall Bridge: Download the latest version from the official site and reinstall.

Trezor® Bridge FAQs

Q1: Is Trezor® Bridge safe? Could it be spyware? A: The official Bridge from trezor.io/bridge is safe and open-source. It cannot access your keys or seed. Never download it from anywhere else, as malicious versions could exist.

Q2: Do I need Bridge if I only use the Trezor® Suite Desktop App? A: No, you can safely uninstall Bridge. The Suite Desktop App communicates directly via USB and doesn't require it. Bridge is only needed for browser-based access.

Q3: Why does the Suite Web App say "Connect Trezor" even with Bridge installed? A: This is common. Force restart your browser completely. Also check Bridge is running, try a different USB port/cable, and ensure no other software has control of the device.

Q4: Does Bridge work on phones or tablets? A: No. Bridge is for desktops/laptops only. Use the Trezor® Suite app for mobile (iOS/Android), connecting your Trezor® physically via USB. No Bridge involved.

Q5: Is "login.trezor-bridge.io" a real site? A: NO! This is a dangerous phishing site. Trezor® Bridge has no login page. Legitimate interaction requires entering your PIN only on your Trezor® device after connecting via official sites like suite.trezor.io.

Q6: Can I use Bridge to log into exchanges? A: No. Bridge only enables communication between your Trezor® and specific web applications designed for hardware wallet interaction (like Suite Web or MEW). Log into exchanges using their standard methods.
