The Ledger Live mobile app brings the full functionality of the desktop version to your smartphone, allowing for complete **on-the-go management** of your crypto assets. The key difference lies in the way the application communicates with your physical Ledger device.
## Connection Methods: Bluetooth vs. USB-C
The **Ledger Nano X** utilizes a secure, low-energy **Bluetooth** connection for wireless communication with the Ledger Live mobile app. This allows you to check balances and sign transactions without needing a cable.
Key Steps for Pairing:
- Turn on your Nano X and enter your PIN.
- Enable Bluetooth on both your Ledger and your phone.
- In the Ledger Live app, initiate the pairing process.
- **Verification is Critical:** Confirm the unique pairing code displayed on your phone matches the code shown on the Nano X screen. This protects against connecting to a malicious third-party device.
For the **Ledger Nano S Plus** (and as an option for the Nano X), you must connect the device directly to your smartphone using the appropriate **USB-C cable** or an adapter (e.g., USB-C to Lightning).
Cable Connection Requirements:
- Ensure your phone supports **OTG (On-The-Go)** functionality if you are on Android.
- Use a reliable, high-quality cable, preferably the official one provided by Ledger.
- The connection is mandatory for signing transactions, managing apps, and updating firmware on the S Plus.
- Keep the phone charged, as the Ledger device draws power from the connected phone when active.
## Mobile-Optimized User Flow
The mobile interface is streamlined for efficiency, prioritizing quick checks and easy navigation across the core sections.
Portfolio View & Discreet Mode
The primary view is your total portfolio value. The mobile app features a **Discreet Mode** (often activated by shaking or tapping the balance) that temporarily hides your balances, displaying them as asterisks (`***`). This is essential for privacy when checking your portfolio in public or around others.
Simplified Send/Receive
The central **Action button** (often a large plus or arrow icon) provides instant access to the Send, Receive, Buy, and Swap features. For receiving, the mobile app allows you to easily share the verified receiving address via standard mobile share options (QR code, messaging apps).
PIN Lock & Biometrics
The Ledger Live mobile app is protected by a separate application PIN, which can be secured using your phone's native **biometric authentication** (Face ID or fingerprint). This secondary PIN protects the app from unauthorized viewing if your phone is lost or compromised, though it's important to remember this PIN is *separate* from your device PIN.
## Management and Firmware on Mobile
While the desktop app is often preferred for major updates, the mobile app can handle most device maintenance functions, especially with the Nano X via Bluetooth.
-
•
App Installation & Removal: You can use the **Manager** section on the mobile app to install, update, and remove crypto applications on your Ledger device. This is often faster via **Bluetooth** (Nano X) than tethering to a computer.
-
•
Firmware Updates: **Firmware updates** (the Ledger device's operating system) can be initiated via the mobile app, but they often require a **wired connection (USB-C)** and a stable power source due to the critical nature of the process. Always ensure your device is fully charged before attempting a firmware update.
-
•
Clear Cache: Just like the desktop version, the mobile app may need a **cache clear** if balances or transaction histories appear incorrect or incomplete. This is found in the Settings menu and forces a full re-synchronization with the blockchain.
Mobile Security Precaution
Be highly cautious of **phishing attempts** via SMS or mobile notifications that claim to be Ledger. Ledger will never send unsolicited messages asking you to confirm your Recovery Phrase, update your device immediately with a link, or send funds to a verification address.
