How Trezor Bridge works — simple architecture, strong security
        Trezor Bridge runs a small, local service on your computer that provides an authenticated channel between applications (like Trezor Suite or browser wallets) and your Trezor hardware wallet. When a wallet or app requests to sign a transaction, Trezor Bridge forwards the request to the device. The device then displays the transaction details on its tamper-resistant screen. You verify and approve on-device; the device produces a signed transaction which is returned through Trezor Bridge to the requesting application. This flow guarantees that private keys never leave the hardware wallet and that the final approval always occurs where the keys reside.
        Connection model
        The connection model is intentionally clear and secure: application ⇄ Trezor Bridge ⇄ Trezor device. Trezor Bridge takes care of local transport, permissions and driver handling, but it does not have access to private keys. The device itself remains the root of trust and the source of signatures.
        Security benefits
        Using Trezor Bridge preserves hardware wallet security benefits while making interactions with web apps convenient. Because all confirmations happen on-device and the Bridge simply relays requests and responses, the combined model offers a strong guarantee: you physically confirm actions on the device, while Trezor Bridge provides the reliable, official connection required by modern apps.
      
      
        Features & benefits — why Trezor Bridge matters
        Trezor Bridge delivers several benefits for everyday and advanced users. It simplifies device pairing, provides consistent behavior for apps across platforms, handles driver issues on desktops, and offers a documented interface for developers. With Trezor Bridge you get:
        
          - Official maintenance: updates and compatibility fixes from the Trezor team.
- Cross-platform support: Windows, macOS, Linux and browser integrations.
- On-device confirmations: all sensitive approvals occur on the hardware screen.
- Developer friendliness: APIs and docs for third-party wallet integrations.
- Simple troubleshooting: clear steps to restart, reinstall or update Bridge when needed.
Daily use tips
        Install Trezor Bridge once and leave the service available while you connect your wallet. Restart browsers after installation. When connecting to a new web app, perform a small test transaction. Always confirm the destination address on the Trezor device screen before approving. Keep both Bridge and device firmware updated for the best security posture.
      
      
        Troubleshooting & best practices
        Common issues with Trezor Bridge are usually simple to resolve: try reconnecting the USB cable, use a different port, restart the Bridge service, or reinstall the official Bridge installer. Disable conflicting browser extensions if browser-based wallets cannot see the Bridge. If problems persist, update your device firmware via Trezor Suite and consult official support resources. Always ensure you downloaded Trezor Bridge from the official site to avoid tampered installers.
        Backup reminder
        Trezor Bridge is a communication layer — not a backup. Your recovery seed is the only reliable backup of your wallet. Secure your recovery seed offline (paper, metal plate, safe deposit box) and never input it into a computer or online form. Trezor Bridge simply enables secure communications; it does not store or manage your seeds.
