Introduction — what is TTrezor® Bridge? 🤔
TTrezor® Bridge is a small background application that enables secure communication between your Trezor hardware wallet and web applications (like Trezor Suite or supported web wallets). It acts as a secure "translator" over the USB connection so your browser and device can talk safely. This guide walks you through downloading, installing, verifying, and troubleshooting TTrezor® Bridge, plus practical security tips to keep your crypto safe. 🚀
Why Bridge matters — security & compatibility 🔗
Browsers limit raw USB access for security reasons. TTrezor® Bridge provides a controlled, auditable channel between your computer and device. It ensures the data sent to the device is minimal and signed where necessary, and that only authorized web pages can initiate a connection. In short: it reduces attack surface while preserving usability. ✅
Quick install — step by step 🛠️
- Download: Get the latest TTrezor® Bridge installer from the official source. Always use the vendor's official site. 🔎
- Run installer: Open the downloaded file and follow on-screen instructions. On macOS, allow the system prompt if it asks for permission. On Windows, you may need admin rights. 💻
- Restart browser: After installation, close all browser windows and reopen them so the browser recognizes the Bridge service. 🔁
- Connect device: Plug in your Trezor device with a good USB cable. When prompted, authorize the connection on the device display. 🖱️
- Open web wallet: Visit the supported web app and connect. The page should detect TTrezor® Bridge automatically. If it doesn't, check the service is running in system tray / background. 🧭
Tip: Use the cable that came with your device — some charge-only cables don't allow data transfer. ⚠️
Verifying the install — simple checks ✔️
- Is the Bridge process running? Look for
ttrezor-bridge(or similarly named) in your system processes. - Does the device show a connection prompt on-screen? If the device requests confirmation, that's good — it means the hardware and Bridge communicated.
- Open the official suite or supported web app and verify it lists your device model and firmware version.
Troubleshooting — common problems & fixes 🩺
Problems are usually simple to fix. Here are common scenarios:
- Browser won't detect device: Close the browser, ensure Bridge is running, reopen browser. Try a different browser if needed.
- Device not powering: Try another USB port or cable. Avoid USB hubs for initial tests.
- Permissions error (macOS): System Security may block installation. Open System Preferences → Security & Privacy and allow the app if you see a blocked prompt.
- Firewall/antivirus blocked: Temporarily allow Bridge through firewall rules — check only official app and processes are permitted.
Security best practices — protect your keys 🛡️
Your Trezor stores cryptographic keys offline — treat the device and its recovery phrase like cash. A few golden rules:
- Never share your 12/24-word recovery phrase. No legitimate support will ask for it. 🚫
- Keep firmware up to date; only install firmware from the official source and verify checksums if provided. 🔄
- Use a trusted machine and avoid public or shared computers when accessing funds. 🖥️
- When using TTrezor® Bridge, confirm the website's URL and use HTTPS. Prefer bookmarks for important wallet sites. 🔐

Q: Is Bridge required? A: For many browsers and web wallets, yes — it enables USB communication safely.
