Ledger Login simplifies authentication by combining hardware-backed keys, privacy-first design, and one-click user flows. Sign in to wallets, dApps and Web3 services without exposing private keys — Ledger holds the key, you keep control.
Private keys remain on your device — never shared. Authentication uses cryptographic signatures isolated from the browser.
No centralized profile. Ledger Login verifies ownership without creating profiles or storing personal data.
For developers: simple SDKs to add Ledger Login to wallets, marketplaces, and DeFi apps.
Ledger Login is built on proven cryptographic standards and hardware secure elements. Our design assumes adversaries: keys never leave the secure element, and signing requires user intent via a physical confirmation on the device. This reduces attack surface and keeps custodial risk far lower than password-only systems.
Ledger Login uses public-key cryptography: when you register a service, your device creates a unique key pair for that service. The private key remains sealed in the hardware secure element; the public key is stored by the service. To sign in, the service issues a challenge — your Ledger signs locally after you approve it on the device. That cryptographic proof is validated by the service, granting access without transmitting secrets.
Yes. The recovery phrase is the ultimate backup for your private keys. Ledger Login reduces online risk, but the recovery phrase remains critical for device recovery.
Can services track me across sites?No — Ledger Login issues site-specific keys, so a key from one service cannot be used to identify you on another. Privacy is built into the key model.
What happens if I lose my device?Restore with your recovery phrase on a new Ledger device. For extra safety, enable a secondary recovery method on services that support it.
