How to change Trezor auto-lock timer? (Display settings)

Display Timeout Configuration

1. Connect the Trezor device to a computer using the original USB cable and ensure it is powered on.

2. Open Chrome browser version 50 or higher and navigate to https://suite.trezor.io.

3. Log into Trezor Suite with your device connected; the interface will detect the hardware wallet automatically.

4. Click the gear icon in the top-right corner to access Settings.

5. Select Device from the left-hand navigation menu, then locate the Display timeout option.

6. Choose a value from the dropdown: 30 seconds, 1 minute, 2 minutes, 5 minutes, or 10 minutes.

7. Confirm the change by pressing the green checkmark button on the Trezor screen when prompted.

Firmware Dependency

1. Auto-lock timer adjustment requires firmware version 2.5.2 or newer for Trezor Model T.

2. Trezor Model One supports display timeout changes starting from firmware 1.10.4.

3. If the Display timeout option does not appear, update the firmware via Trezor Suite before proceeding.

4. Firmware updates must be initiated from the official Trezor Suite interface — third-party tools are unsupported and may compromise security.

5. During firmware installation, the device screen displays progress bars and confirmation prompts; users must physically verify each step on-device.

Security Implications of Timeout Selection

1. A shorter timeout like 30 seconds reduces exposure risk if the device is left unattended near unauthorized persons.

2. Longer intervals such as 10 minutes increase convenience during multi-step transaction signing but extend the window where an unlocked device could be misused.

3. The auto-lock mechanism does not affect PIN entry attempts — failed PIN entries still trigger progressive delays independent of display timeout settings.

4. Display timeout resets only upon successful PIN entry or passphrase input; screen dimming begins immediately after last interaction.

5. No biometric authentication bypasses this timer — all Trezor models rely solely on physical button confirmation and PIN verification.

Recovery Seed Interaction

1. Changing the display timeout has no effect on recovery seed generation or backup procedures.

2. When entering the recovery seed during setup, the device enforces a fixed 60-second timeout per word, regardless of configured display timeout.

3. Recovery mode disables all user-configurable timers and reverts to hardened defaults for cryptographic safety.

4. Seed verification screens remain visible until manual confirmation, even if the general display timeout has expired.

5. Writing down or storing the recovery seed off-device remains mandatory — no setting alters this requirement.

Common Questions and Answers

Q: Does changing the display timeout affect how long my Trezor stays connected to Trezor Suite?A: No. Connection persistence depends on USB power and host system behavior, not the display timeout setting.

Q: Can I disable auto-lock entirely?A: No. Trezor devices do not support disabling auto-lock. The shortest available option is 30 seconds.

Q: Will adjusting the timeout impact transaction signing speed?A: Not directly. Signing operations proceed at hardware speed, but a timed-out display requires re-entering the PIN before continuing.

Q: Is the display timeout stored on the device or in Trezor Suite?A: It is written directly to the device’s secure memory during configuration and persists across reboots and disconnections.
