This guide explains why the standalone Trezor Bridge has been deprecated and removed, what that means for your Trezor hardware (Model One and Model T), and the recommended migration path to the integrated connection methods provided by Trezor Suite. It also covers how Trezor Connect, WebUSB, backups, and device protection are affected and what you should do next to secure your wallets and keep your onboarding friction-free. :contentReference[oaicite:1]{index=1}
Trezor deprecated the standalone Trezor Bridge to streamline the user experience and reduce the complexity of multiple connection layers. The standalone Bridge—previously used as a local conduit between browser apps and Trezor devices—has been phased out in favor of modern connection approaches integrated directly into Trezor Suite and browser-native APIs like WebUSB. If you still run a standalone Bridge installation, Trezor recommends uninstalling it and migrating to the supported solutions. :contentReference[oaicite:2]{index=2}
Both the Model One and Model T remain fully supported, but connection mechanics differ based on firmware and host software:
Older Model One devices using legacy HID transport may not be automatically detected by newer Trezor Suite versions unless firmware is updated. If you run an older firmware (pre-1.7.0 for some legacy devices), you may need to update the device firmware using a supported flow in Trezor Suite to re-enable discovery and device management. Always back up your recovery seed before any firmware operations. :contentReference[oaicite:5]{index=5}
Model T users should experience a smoother transition because newer devices and firmware are fully compatible with the Suite’s transport stacks and with WebUSB in supported browsers (Chrome family). Model T benefits from a richer UI in Trezor Suite for wallet onboarding, device protection settings, passphrase options, and secure backup prompts. :contentReference[oaicite:6]{index=6}
The recommended migration path is to install Trezor Suite (desktop or web). Trezor Suite bundles the necessary transport layer (previously provided by Bridge) and offers in-app firmware updates, clearer wallet onboarding, and advanced features such as Trezor Safe 3 and Trezor Safe 5 flows (multisig and enhanced safe-management patterns). If you prefer web integrations, Trezor Connect and WebUSB provide modern browser APIs for dApps and web wallets to interact with your Trezor device. :contentReference[oaicite:7]{index=7}
Nothing about the deprecation changes the fundamentals of secure key custody: always maintain a secure recovery Backup of your seed phrase and use the device protection options offered by Trezor. The hardware’s open-source design continues to provide transparency into the device firmware and hardware, while the integrated Suite and Connect stack improve usability without changing the underlying cryptographic trust model.
During wallet onboarding in Trezor Suite, you’ll be guided through secure recovery seed creation and backup. Use physical, offline storage for your recovery seed; avoid digital copies or screenshots. The onboarding flow in Suite is designed to encourage secure device protection and backup best practices. :contentReference[oaicite:9]{index=9}
Mentions of Trezor Safe 3 and Trezor Safe 5 refer to evolving wallet-management paradigms (for example, different multisig or safe-protection patterns) that benefit directly from Suite’s integrated environment. With the standalone Bridge removed, these safe-management features are easier to discover and use in the Suite’s UI, and dApp integrations can leverage Trezor Connect for consistent behavior. The shift to Suite helps ensure these advanced flows are battle-tested and user-friendly. :contentReference[oaicite:10]{index=10}
If Trezor Suite does not detect your device after migrating away from the standalone Bridge, consult the official troubleshooting guides. Common fixes include updating device firmware, ensuring your OS and browser meet the required OS requirements, checking USB permissions, and removing any legacy Bridge remnants. Specific notes indicate that older Model One devices with legacy HID transport may require firmware updates for detection. :contentReference[oaicite:11]{index=11}
For developers and dApp builders, the deprecation means fewer compatibility hurdles. Trezor Connect remains the recommended method to interface web apps with Trezor devices, providing a stable, documented API for signing and transaction flows. WebUSB support continues to allow direct browser device connections where supported (notably in Chromium-based browsers). dApp integrators should prefer Trezor Connect or Suite-ready approaches over relying on end users to install a standalone Bridge app. :contentReference[oaicite:12]{index=12}
The deprecation of the standalone Trezor Bridge is a maintenance-driven, usability-first decision that tightens the update and security model by moving functionality into the Suite and modern browser APIs. Your private keys and backup responsibilities remain unchanged — the recommended actions are to migrate to Trezor Suite, follow wallet onboarding best practices, and verify backups and device protection options to keep your assets safe.
