Why Trezor Bridge matters (H4)
Trezor Bridge provides a secure, standardized channel between browser environments and the hardware. Because modern browsers restrict direct USB access for security reasons, the Bridge acts as an authorized intermediary that only runs locally. It prevents sensitive flows from traversing remote servers and reduces friction when updating, signing, or onboarding multiple devices.
Security best practices (H5)
- Always download Bridge from the official Trezor domain and verify checksums where available.
- Never enter your recovery seed on a computer or online form β it belongs only on paper or steel backup in cold storage.
- Use a strong PIN and enable passphrase features for additional account-level separation.
- Keep firmware updated via Trezor Suite; updates often close attack windows and add compatibility.
