How to pair your device (step-by-step)
Pairing must be done carefully to avoid accidental connections or man-in-the-middle attempts. Below is a safe, practical workflow for pairing a Ledger Nano X with your mobile device via Ledger Live App:
- Install Ledger Live App from your platform store and open it.
- Enable Bluetooth on your phone and on the Ledger device (follow device manual to enable pairing mode).
- Follow the app prompts — select "Connect device" and choose your Ledger when it appears in the list.
- Confirm the pairing code shown on the phone matches the code displayed on your Ledger device before approving.
- Approve required permissions — only grant what is necessary and deny broad or suspicious permission requests.
- Complete onboarding and test with a small transaction or receive address verification to ensure everything is functioning correctly.
Troubleshooting common pairing issues
If pairing fails, try toggling Bluetooth, restarting both devices, moving closer, or removing old pairings. On some Android devices, OS-level battery or connectivity optimizers can interfere — temporarily disable them during pairing. For persistent issues, check for firmware updates on the Ledger device and update Ledger Live App to the latest version.
Security & privacy considerations
Ledger Live App is an interface — private keys remain inside the hardware device. Mobile workflows add convenience but introduce different threat models than desktop: mobile OSes and apps can have different privacy and permission behaviors. Follow these guidelines:
- Install only from the official store and verify the app publisher.
- Confirm pairing codes and approve all actions on the Ledger device screen — never on the phone alone.
- Keep your phone OS updated and avoid installing untrusted apps that request broad permissions.
- Use device PINs and secure lock screens on both phone and Ledger device.
- Consider enabling passphrases for additional account isolation if you can safely manage them.
Privacy trade-offs and network settings
The app communicates with public nodes and third-party services for balance and transaction data. If you require higher privacy, evaluate network settings, local backends, or routing traffic through trusted networks. The mobile app allows limited telemetry control — review settings to minimize data sharing.
Best practices for mobile-first users
Mobile-first users should maintain a strict separation: use mobile apps for monitoring and transaction preparation, and confirm all signing actions on the hardware device. Regularly back up and secure your recovery phrase offline. Avoid public Wi‑Fi when performing sensitive operations and prefer private, trusted networks for pairing and transfers.
