Ledger Live App® — Official Ledger Mobile & Desktop Application

Overview — what Ledger Live is

Ledger Live is the official application produced by Ledger that serves as the primary interface for managing crypto assets with Ledger hardware wallets (Nano S, Nano S Plus, Nano X and others). Available for desktop and mobile, Ledger Live combines portfolio visibility, account management, secure transaction signing, staking, buying and swapping, and device management — all while the private keys remain inside the secure element of the Ledger hardware device. Ledger Live is designed to be both approachable for newcomers and extensible for advanced workflows.

Architecture in one line

Ledger Live = UI & network layer; Ledger device = secure element and signing authority. Transactions are built in the app, reviewed and approved on-device, and broadcast by the app once signed.

Who should use Ledger Live?

• Beginners who want a guided, safe setup experience with hardware-backed security.
• Regular users who want a polished dashboard and integrated services (swap, buy, stake).
• Power users who need PSBT, multisig, or advanced signing workflows in combination with Ledger hardware.
• Enterprises and custodians evaluating device management combined with best practices and governance — Ledger Live forms part of the operational tooling for many institutions.

Download & platform support

Ledger Live is available for Windows, macOS, and Linux (desktop) and for iOS and Android (mobile). Always download Ledger Live directly from Ledger’s official website or the recognized app stores. Ledger provides verified installers and checksums for desktop releases to help verify authenticity.

Platform checklist

• Windows: Windows 10 or later recommended. Use official installers.
• macOS: Recent macOS versions recommended; follow Gatekeeper prompts and verify publisher.
• Linux: AppImage or distribution packages are available — follow Ledger’s Linux instructions for udev rules and dependencies.
• Mobile: Ledger Live on iOS / Android — Bluetooth support required for Nano X; OTG or desktop complement for other devices.

Step-by-step setup (desktop and mobile)

This section walks through a careful setup flow designed to minimize risk and make sure you retain complete control of your recovery seed and device.

Initial preparation

• Choose a trusted machine for the initial setup. Prefer a personal computer with up-to-date OS and security patches.
• Keep the Ledger packaging sealed until you are ready to verify authenticity.
• Have pen & paper or a metal backup kit ready for recording the recovery phrase — never capture it digitally.

Desktop setup

1. Download official Ledger Live from Ledger’s site and install.
2. Open Ledger Live and follow the onboarding wizard: choose "Set up new device" or "Restore device."
3. When creating a new wallet, the Ledger device generates the recovery phrase on-device. Write it down in the exact order shown (24 words by default for new devices).
4. Set a PIN directly on the device (not typed into the host). The PIN prevents casual physical access.
5. Install required blockchain apps using Ledger Live’s Manager.
6. Add accounts in Ledger Live for the chains you’ll use; verify receive addresses on the device each time.

Mobile setup

1. Install Ledger Live from the App Store or Google Play and confirm the publisher is Ledger SAS.
2. Pair a Nano X via Bluetooth following the in-app pairing flow; for wired devices, use OTG or pair via desktop as necessary.
3. Complete the same seed creation and PIN process; ensure the seed is written down and verified via the in-app steps.

Security model & core guarantees

Ledger Live's security model rests on the hardware device being the root of trust. The device contains a secure element (SE) which stores private keys and performs cryptographic operations. The host application (Ledger Live) does not have access to private keys. Crucial operations that change the state of funds — signing transactions — require explicit, physical confirmation on the device screen.

Key guarantees

• Key isolation: Private keys never leave the secure element.
• On-device verification: Transaction details are shown on-device for user confirmation.
• Verified firmware: Ledger devices enforce firmware integrity checks and signed updates.
• Local attestation: Ledger Live can perform checks to verify device authenticity.

Operational advice

• Keep your recovery phrase offline; consider using metal plates for fire/water resilience.
• Use passphrase (BIP39 passphrase) only if you understand the tradeoffs — it creates additional hidden wallets that are not recoverable without the passphrase.
• Use separate devices/accounts for different purposes to compartmentalize risk.

Daily workflows — receive, send, stake, and swap

Receiving crypto

1. Open Ledger Live and choose the receiving account.
2. Click Receive and have the Ledger device display the address.
3. Verify the address on the device screen before sharing it with the sender.

Sending crypto

1. Compose the transaction in Ledger Live (amount, destination, fee).
2. Ledger Live sends the unsigned transaction to the device for signing.
3. Carefully verify amount, destination, and fee on-device and then approve.
4. Ledger Live broadcasts the signed transaction to the network.

Staking & earning

Ledger Live supports staking flows for multiple blockchains. When staking, sign the delegation or staking transaction on-device. Rewards and undelegation rules depend on chain specifics; Ledger Live will present chain-specific guidance where supported.

Swapping & buying

Ledger Live integrates partner services for buying and swapping. These services are third-party providers; Ledger orchestrates the transaction but the final signing happens on your device. Compare rates and fees before confirming.

Advanced topics — PSBT, multisig, air-gapped signing

PSBT (Partially Signed Bitcoin Transactions)

PSBT is a format that enables multi-step signing workflows. Ledger Live supports PSBT workflows that allow air-gapped setups: the host constructs the PSBT, it is transferred to the offline signer (Ledger) for signing, and the signed PSBT is then returned and broadcast by the host. PSBT is invaluable for cold storage, multisig, and highly secure signing arrangements.

Multisignature setups

Multisig reduces single-point compromise by requiring multiple independent signers for a transaction (e.g., 2-of-3). Ledger devices can be used as signers in multisig setups using PSBTs and compatible coordinators. For institutions or families sharing custody, multisig provides governance and disaster recovery benefits but adds operational complexity.

Air-gapped workflows

For the highest security, use an air-gapped host to prepare unsigned transactions and a disconnected Ledger device (or a specialized signer) to sign via PSBT transport (QR, microSD, or removable media depending on tooling). Ledger Live can interact with PSBT files exported/imported by third-party tools to support air-gapped signing.

Developer integrations & ecosystem

Ledger provides APIs and connectors that enable developers to integrate Ledger signing into dApps, wallets, and services. Common integration patterns include: WebHID/WebUSB connectors for browser dApps, native transport on desktop apps, and mobile SDKs for Bluetooth pairing with Nano X. Developers should follow Ledger’s official guides, avoid exposing sensitive material client-side, and always require on-device confirmations for signing.

Security in integrations

• Never assume the host is trustworthy — design for the device to verify and display transaction details.
• Avoid sending extraneous metadata that could leak privacy-sensitive information.
• Respect origin-checking and prompt users clearly before connecting a hardware device.

Troubleshooting — common issues and fixes

Device not detected

• Try a different USB cable or direct USB port; avoid unpowered hubs.
• Restart Ledger Live and the host machine.
• Reinstall or update device drivers (Windows) or add required udev rules (Linux).

Firmware update failures

• Ensure a stable connection and power during the update; never disconnect mid-update.
• Use the desktop Ledger Live installer rather than alternative methods if you encounter problems.

Transaction problems

• Confirm you have the correct blockchain app open on the device (e.g., open Bitcoin app for BTC).
• Check network status and fee settings; retry if necessary.

FAQ — short answers

Can Ledger Live be used without a Ledger device?

Ledger Live requires a Ledger device for signing private-key operations. Some read-only features may be accessible without a connected device, but private keys and signing always require the hardware.

What happens if I lose my Ledger device?

If you have your recovery phrase, you can restore your accounts on a new Ledger or compatible wallet. If you lose both device and recovery phrase, funds may be unrecoverable.

Is Ledger Live open-source?

Ledger maintains portions of its stack as open-source; check Ledger’s repositories and documentation for details on which components are public and how to verify builds.

Operational best practices

• Use dedicated backup solutions (paper + metal) and store backups in separate secure locations.
• Maintain an updated host OS and limit exposure to risky software on machines used for transactions.
• Use small test transactions with new counterparties or smart contracts before moving large sums.
• Consider multisig for high-value holdings and institutional custody to reduce single-point-of-failure.
• Periodically test recovery procedures with a low-value restore to ensure you can recover when needed.
