How can I ensure my Ledger device is using the latest security patches?

Verifying Firmware Authenticity and Integrity

1. Always download firmware updates directly from the official Ledger website to prevent tampering or counterfeit versions.

2. Use the Ledger Live application to check for available firmware updates, as it automatically verifies digital signatures before installation.
3. Confirm the integrity of the firmware by comparing checksums provided on Ledger’s security page with those displayed during the update process.
4. Ensure your device screen displays a verification message when installing new firmware, indicating that the code has been authenticated.
5. Avoid using third-party tools or modified firmware, as these can bypass built-in security checks and expose private keys.

Updating Through Ledger Live Safely

1. Connect your Ledger device to a trusted computer with Ledger Live installed and ensure no malware is present.

2. Open Ledger Live and navigate to the Manager tab where pending firmware updates are clearly indicated.
3. Follow on-screen prompts to initiate the update; the app will verify the firmware before sending it to the device.
4. During installation, confirm the “Install this firmware?” prompt on your Ledger’s physical buttons to authorize the update.
5. After completion, reboot the device and verify the updated version number both in Ledger Live and on the device’s settings menu.

Maintaining Device Security Post-Update

1. Reset your device after a major firmware upgrade only if explicitly instructed—most updates do not require this step.

2. Reinstall apps through Ledger Live post-update, ensuring each application is compatible with the current firmware version.
3. Regularly review connected services and revoke access from unused dApps or wallets via the Settings menu.
4. Enable passphrase protection if used, confirming it functions correctly after the update by accessing hidden wallets.
5. Store recovery phrases offline and never input them into any digital device or software.

Always authenticate firmware updates through Ledger Live and verify on-device prompts to protect against supply chain attacks.

Frequently Asked Questions

How do I know if my Ledger firmware update was successful?Check the firmware version in the device’s settings under “Device information.” It should match the latest release noted on Ledger’s official site. Ledger Live will also display the updated version in the Manager section.
