Why interface software (like Trezor Bridge) matters
Hardware wallets (Trezor®, Ledger® and others) keep your private keys offline. But to sign transactions, the device needs a secure, trusted channel to your computer or mobile. That’s where interface layers such as Trezor Bridge or companion apps like Ledger Live come in — they act as the connector between browser/web apps and the physical device, handling USB or WebUSB traffic and ensuring commands are routed safely.
What changed: Trezor Suite and Bridge deprecation
Trezor historically provided a standalone service called Trezor Bridge to connect devices and browsers. Over time, Trezor has moved much functionality into Trezor Suite, deprecating the standalone Bridge to simplify updates and reduce attack surface. If you still rely on the old standalone Bridge, follow the official removal/uninstall guidance before switching to the suite to avoid conflicts.
Quick security checklist
- Always download Trezor or Ledger software from the official domains listed below.
- Never enter your recovery seed into a desktop app or web page — hardware wallets never ask for it during normal use.
- Keep firmware and companion apps up to date via official channels.
- Be suspicious of unsolicited support links or apps — phishing is common.
Step-by-step: Connecting a Trezor® device safely (modern flow)
1. Verify official source
Download Trezor Suite from the official site or use the official web app. Avoid third-party download mirrors.
2. Uninstall old/standalone Bridge (if present)
If you have a legacy installation of Trezor Bridge, uninstall it using the official instructions before installing the latest Trezor Suite to prevent conflicts.
3. Connect, confirm firmware, and verify device
Once Trezor Suite (or a trusted web interface) detects your device, confirm the device display and fingerprint — always verify the device’s screen prompt and the first words of its randomized origin text. Never trust only what shows in your browser.
Optional: Using Ledger® with its official app
Ledger users should rely on Ledger Live (desktop or mobile) and only update firmware via the app. Ledger also publishes detailed support and security guidance on their official site.

Common pitfalls and how to avoid them
Phishing & fake apps
Attackers sometimes imitate Ledger Live or Trezor Suite installers. Always confirm domain names and checksums when published. Ledger publicly documents phishing campaigns and recommends downloading only from ledger.com. If an interface ever asks for your seed words, it's malicious — disconnect immediately and report it.
Mixing old & new connectors
Legacy bridge services can conflict with modern suite apps. If you see connection failures after upgrading, check for running background bridge/daemon processes and follow official uninstall steps before reinstalling the modern suite.
