What are the best security practices for Ledger Nano X?

Secure Setup of Your Ledger Nano X

1. Always purchase your Ledger Nano X directly from the official Ledger website or an authorized reseller to avoid tampered devices.

2. Upon receiving the device, verify the packaging integrity and confirm the authenticity code on the Ledger website before setup.
3. During initial setup, generate a new 24-word recovery phrase and never store it digitally—write it down on paper or use a metal backup solution.
4. Never let anyone else view or record your recovery phrase during setup.
5. Confirm that the recovery phrase displayed on the device matches exactly what you’ve written down before proceeding.

Protecting Your Recovery Phrase

1. Store your recovery phrase in a secure physical location such as a safe or safety deposit box, away from moisture and fire hazards.

2. Never take a photo, screenshot, or save your recovery phrase on any connected device, including phones or computers.
3. Avoid using third-party apps or cloud services to back up your seed phrase—these are common attack vectors.
4. Consider using a passphrase (25th word) for additional protection, which adds a layer of stealth mode if compromised.
5. Test your recovery process in a secure environment by restoring a test wallet to ensure your backup works correctly.

Safeguarding Transactions and Device Usage

1. Always verify transaction details directly on the Ledger Nano X’s screen before approving with button presses.

2. Be vigilant against phishing attempts—only download the Ledger Live app from the official website.
3. Regularly update the firmware through Ledger Live, ensuring you're running the latest security patches.
4. Enable the PIN lock feature and choose a PIN that isn’t easily guessable or reused across other accounts.
5. If someone forces you to reveal access, entering an incorrect PIN three times will wipe the device, protecting your assets.

Maintaining Long-Term Security

1. Disconnect your Ledger Nano X after each session to prevent unauthorized access via connected cables.

2. Avoid using public or untrusted computers to interact with your device.
3. Use strong, unique passwords for your Ledger Live account and enable two-factor authentication.
4. Monitor your wallet addresses regularly for unexpected transactions or changes.
5. Periodically review connected apps in Ledger Live and remove unused or suspicious ones.

Frequently Asked Questions

What should I do if I lose my Ledger Nano X?If you lose your device, your funds are still secure as long as your recovery phrase is protected. Purchase a new hardware wallet, preferably another Ledger, and restore your accounts using the 24-word phrase. Ensure no one else has accessed the phrase.

Can malware on my computer steal my crypto even with a Ledger Nano X?While the private keys remain secure on the device, malware can manipulate transaction details during signing.
