Trezor Login

Guidance for signing in securely using a Trezor hardware wallet and web services.

How Trezor login typically works

Many web services offer login flows that use a hardware wallet for authentication or transaction confirmation. The general flow is:

  1. User visits a service and initiates a sign-in or authorize action.
  2. The service prompts the browser to request a cryptographic signature from the Trezor device via Trezor Bridge or WebUSB.
  3. The user confirms the action on the physical device screen (always verify details shown).
  4. The signed payload is returned to the website, which verifies it and completes the login or authorization.

Safety first: avoid phishing

Before you sign anything, verify:

  • The page URL is correct — check the domain carefully.
  • The full text of the message or transaction is what you expect.
  • Your device screen shows matching details and asks for confirmation.

Common protections

  • Confirm every signature on the Trezor screen; do not rely only on the browser text.
  • Use unique accounts per service where practical.
  • Log out from services after use and avoid auto-login on shared machines.

What to do if something looks wrong

  1. Cancel the signature request on the device.
  2. Disconnect the device and close the browser tab.
  3. Verify the service's URL and contact their support if needed.

Note: This page describes general patterns for "Trezor login" flows. Exact behavior depends on the service and how it integrates hardware wallet authentication.

Developer note

If you're implementing a Trezor-based login, use standard challenge-response signatures, include nonce/timestamp to avoid replay attacks, and present clear messages for users to confirm on-device.

Example (conceptual)

// PSEUDOCODE (conceptual only)
// server: create challenge = random();
// server: send challenge to client
// client: request device to sign challenge
// device: user confirms, returns signature
// server: verify(signature, userPubKey)

Final notes

Always prefer official integrations and validate any third-party service before granting access. This page is informational and not an official Trezor product page.
