What is Trezor Bridge?
Trezor Bridge is a lightweight communication application that runs on your computer and provides a secure channel between your Trezor® Hardware Wallet and browser-based services like trezor.io/start or the Trezor® Suite App. It replaces older browser plugins and enables device discovery, firmware updates, and transaction signing while keeping private keys on the hardware device.
Why you need it
When you use the Trezor® Wallet or the Trezor® Suite (desktop/web), Trezor Bridge handles USB communications so the browser or app can safely talk to your device without exposing sensitive data. It’s essential for tasks like Trezor login, account recovery, and firmware installation.
How to download & install
To install, visit the official trezor.io/start page and follow the prompts to download Trezor Bridge Download for Windows, macOS, or Linux. After installation, reconnect your Trezor® device and open Trezor® Suite or trezor.io to complete setup.
Tip: Only use official links to download Bridge—this prevents malicious software from intercepting your device communications.
Troubleshooting common issues
Problems like Trezor login not working, Unable to login Trezor, or Error Connecting Trezor Account often stem from an outdated Bridge, a blocked USB port, or antivirus software blocking connections. Steps to fix:
- Restart computer and reconnect the Trezor® device.
- Re-install the latest Trezor Bridge.
- Try a different USB cable or port (avoid USB hubs).
- Temporarily disable antivirus or allow the Bridge app in firewall settings.
- Open Trezor® Suite and check for firmware updates.
Account recovery & 2FA
If you see issues with account access, such as Trezor Account Recovery or a needed Trezor 2fa reset, follow the official recovery procedure using your recovery seed—never share it. For 2FA reset or web-account issues, consult the Trezor Help Center for account-specific instructions and secure verification steps.
When Trezor® Suite App not Working or Can't verify wallet
If the Trezor® Suite App fails to detect your device or you “Can't verify Trezor Wallet,” verify Bridge is running, confirm browser permissions, and ensure your device is unlocked with PIN. If problems persist, backup the recovery seed and seek help from official Trezor support channels.
