Trezor Secure Access — Advanced Protection for Every Login®

Understanding the verification and encryption layers that guard device interactions.

Security model

Access is gated by physical device confirmation and cryptographic signatures. The device generates signatures that prove intent without exposing keys to the host computer.

Key protections

  • On-device display for transaction details
  • Ephemeral session tokens and origin scoping
  • Signed messages with clear intent and metadata

Operational guidance

  1. Always verify the address on-device before approving.
  2. Use hardware-backed U2F or WebAuthn where possible for account access.
  3. Keep companion apps and firmware up to date from official resources.
