Golden Security Rule: Never Share Your 24-Word Recovery Phrase

Your 24 secret recovery words represent full access to all your crypto funds. Ledger employees, support staff, or legitimate applications will NEVER ask for your seed phrase. Never enter recovery words into any computer keyboard, website, screenshot, or mobile app.

Complete 4-Step Initialization Walkthrough

Follow standard security protocols to unpack, verify authenticity, generate your keys, and configure client software safely.

PHASE 01

Unbox & Inspect Hardware Authenticity

Verify the original sealed package contents: the device, USB cable, recovery sheets, and instruction leaflets. Crucially, the 24-word recovery sheet must always arrive blank. If pre-filled words are present in the box, never power on the device; contact support immediately.

PHASE 02

Download Client Application via Ledger.com/start

Navigate to the official starting address directly by typing it into your browser. Install the verified desktop or mobile client. During pairing, the application runs a cryptographic genuine check to guarantee your hardware device has not been tampered with in transit.

PHASE 03

Configure 4-8 Digit PIN & Generate 24 Words

Select 'Set up as new device' directly on the physical hardware screen. Choose a robust numeric PIN code. The embedded True Random Number Generator (TRNG) will then produce your unique 24-word recovery phrase. Write each word down on paper in precise sequential order.

PHASE 04

Install Asset Apps & Perform Test Transfers

Use the App Catalog to install individual coin applications (Bitcoin, Ethereum, Solana, etc.). Always perform an initial small test transaction when sending crypto into cold storage. Physically cross-check destination addresses on your device's trusted OLED screen.

Why Secure Elements & Clear Signing Matter

Software wallets on everyday computers and smartphones are constantly exposed to operating system vulnerabilities, malware, clipboard hijacking, and phishing traps. A dedicated hardware wallet isolates private cryptographic credentials inside a certified Secure Element (ST33 chip family) running a proprietary operating system (BOLOS).

In cryptography, security is binary: either your private keys are completely isolated from online compute environments, or they are vulnerable to remote extraction. Cold storage with on-device screen verification eliminates blind signing risks.
Hardware Architecture & Cryptographic Best Practice

Tamper-proof Secure Element withstands sophisticated physical and laser attacks.

Clear Signing transparency shows actual destination smart contracts on-screen.

Secure firmware updates signed only with manufacturer master cryptographic keys.

HARDWARE ISOLATION

BOLOS Modular Security Architecture

Unlike generic microcontrollers, the proprietary OS ensures individual cryptocurrency apps run in complete isolation from one another. Even if a third-party token app contains an anomaly, it cannot access the core cryptographic seed or other accounts.

DEFENSE AGAINST EXTORTION

Secondary PIN & 25th Word Passphrase

Advanced users can configure an optional 25th passphrase word tied to an alternative secondary PIN code. This enables a plausible deniability setup where a decoy wallet opens with the primary PIN while high-value vaults remain concealed behind the second PIN.

Frequently Asked Setup Guidance & Troubleshooting

Quick answers to common device pairing, battery, network connection, and recovery questions.

What happens if I enter the PIN code incorrectly 3 times?

As an integrated brute-force defense mechanism, the Secure Element will automatically wipe all internal data and reset to factory condition. You can immediately restore your accounts by choosing 'Restore from Recovery Phrase' and entering your original 24 words.

Can I store multiple cryptocurrencies on one device?

Yes. Your 24-word seed generates deterministic derivation paths for all blockchains simultaneously. You can install and uninstall individual coin apps as needed without affecting your underlying balance or transaction records.

How do I perform a safe firmware upgrade?

Only trigger firmware upgrades inside the officially installed desktop manager. Make sure you have your physical 24-word recovery sheet with you before initiating any update as a standard safeguard, then verify the update hash displayed on the device screen.

Where is the safest place to store recovery sheets?

Store recovery sheets in a fireproof, waterproof safe or consider engraving words onto an indestructible stainless steel/titanium capsule. Never store seeds digitally, in cloud drives, note-taking apps, or password managers.
