Trezor Login is not a username/password system. It's the process by which your physical Trezor® hardware device establishes a secure session with the Trezor Suite application so you can sign transactions and manage assets.

• Authentication factors: device possession + PIN (+ optional passphrase).
• Private keys remain on-device; Suite only receives signed data.
• Device attestation and session fingerprinting mitigate MITM risks.

1. Confirm official Suite app downloaded from trezor.io/start.
2. Inspect device packaging for tamper-evidence.
3. Have Recovery Seed card(s) available for demonstration (never use live funds with exposed seed).
4. Use an isolated demo environment or testnet funds for live demos.
5. Ensure firmware and Suite versions are up to date.

1. Launch Trezor Suite and choose "Connect device".
2. Connect the Trezor via USB — confirm device powers on.
3. Enter your PIN on the device screen when prompted — PIN entry is performed on-device.
4. Verify session fingerprint on both device and Suite, then approve connection.
5. Access accounts and balances through the Suite UI.

Speaker tip: highlight the importance of verifying the fingerprint and never entering the seed into the host machine.

• PIN: Device access control — prevents casual physical misuse. Should be memorized and not obvious.
• Passphrase: Optional secret that creates hidden wallets — suitable for deniability and advanced security.
• Use-case examples: family shared custody, enterprise separation of duties, hidden high-value accounts.
• Operational note: losing a passphrase is equivalent to losing the wallet. Only recoverable with correct seed + passphrase.

The Suite and device exchange a session public key and a fingerprint. The device displays a short fingerprint which you must compare with the Suite. Approving this fingerprint ensures you are connecting to the legitimate app instance and not an impersonator.

• Do: Compare fingerprints visually each session.
• Do: Re-check after updates or if connecting from a new host.
• Don't: Blindly approve connection prompts.

• Keep Recovery Seed offline in a secure physical location (safe, vault, or split-storage).
• Never share your seed or passphrase with anyone — support will never ask for it.
• Use passphrases for sensitive accounts and segregate funds across multiple hidden wallets.
• Verify transaction details on-device before approval.
• Minimize software installed on hosts used for managing funds.

1. Switch USB cable and USB port; try a different host computer.
2. Confirm device powers on — if not, verify cable and safe power supply.
3. Restart Suite and the host machine; check for OS driver prompts (on Windows/macOS).
4. Confirm browser permissions for web Suite (if using web version).
5. Reinstall Suite if the app is corrupted; keep metadata backups if necessary.

• If you forget PIN: recover wallet on a new device using the Recovery Seed (PIN cannot be recovered).
• If balances missing: check passphrase variations, including empty passphrase if one wasn't set.
• If device locked from failed attempts: wait out the exponential backoff or recover via seed on a fresh device.
• Test recovery regularly on a disposable device to ensure seed integrity (use testnet or small amounts).

PSBT (Partially Signed Bitcoin Transaction) workflows enable an offline signer to sign transactions prepared by an online broadcaster. This allows the signing device to remain air-gapped.

• Prepare unsigned PSBT on an online machine.
• Transfer PSBT to offline signer via USB or QR.
• Sign on the offline device; export the signed PSBT back to the online broadcaster.
• Broadcast the signed transaction to the network.

• Use multisig schemes to reduce single-point-of-failure risk.
• Keep hardware distributed across geographic locations with strict access controls.
• Rotate custodians and implement quorum controls and audits.
• Maintain tamper-evident logs and device custody chains.

Trezor devices use signed firmware and attestation data to allow Suite to verify device authenticity. Always apply firmware updates from official sources and verify attestation when prompted.

• Do: Accept firmware updates only from trezor.io.
• Do: Verify attestation prompts on a first-use or replaced device.
• Don't: Install untrusted or community-modified firmware in production environments.

• Q: Can I log in without my device?
  A: No — signing requires the physical device or recovery seed for full restoration.
• Q: Support asks for my seed — should I share?
  A: Never share your seed. Legitimate support will never request it.
• Q: Suite shows no balance?
  A: Check network selection, passphrase, and account discovery settings.

1. Trezor Login is secure when you follow best practices: verify fingerprints, protect seed & passphrase, and verify transactions on-device.
2. Use air-gapped signing and multisig for high-value custody.
3. Practice recovery and keep operational procedures documented and tested.
