Ledger Login

Safe, Private Authentication for Wallets

Safe, private authentication for your crypto wallets and Web3 accounts

Ledger Login lets you sign in to wallets, dApps, marketplaces, and DeFi services using hardware-backed credentials. Your private keys stay on your Ledger device; services receive cryptographic proof of ownership. That means fewer passwords, less phishing risk, and stronger privacy for every user.

Hardware-backed

Private keys are generated and stored inside the secure element of your Ledger device. Signing happens locally — the key never leaves the device.

Per-site credentials

Each service receives a unique key pair so sites cannot correlate your identity across platforms. Privacy is built-in.

Phishing resistance

Every signature requires a physical confirmation on your device, preventing remote or automated sign-ins even on compromised computers.

How Ledger Login works

When you register a service, your Ledger generates an origin-bound public/private key pair. The public key is shared with the service; the private key remains sealed. To sign in, the service issues a challenge. You approve the challenge on your device; the device signs it locally. The service verifies the signature with the stored public key and grants access. No passwords, no secrets transmitted.

Quick user flow

  • Set up Ledger and record your recovery phrase in a secure offline location.
  • Choose "Sign in with Ledger" on a supported site and connect your device via USB or Bluetooth.
  • Confirm the sign-in prompt on your Ledger device. Access is granted instantly.

Why this is safer than passwords

Traditional passwords and centralized identity systems are attractive targets for attackers. Ledger Login eliminates the need to transmit or store passwords on servers, reducing the risk of credential stuffing and data breaches. Because signing is performed inside a hardware secure element and requires physical confirmation, attackers cannot sign on your behalf even if they control your browser or server.

Technical protections

  • Secure element stores private keys and enforces PIN-protected access.
  • Cryptographic challenges prevent replay attacks.
  • Per-origin keys ensure service-specific credentials and prevent tracking.

Privacy-first approach

Ledger Login is designed so services cannot build cross-site profiles. By issuing unique keys per origin and minimizing data exchange during authentication, users keep control over their identity. Services verify ownership, not personal attributes.

For developers

Integrate Ledger Login using WebAuthn-compatible flows or our SDKs. Create origin-bound credentials, request signed challenges from clients, and validate signatures server-side. Offer users a simple flow that is resistant to phishing and account takeover attacks.

// Request a challenge from the server fetch('/auth/challenge', {method:'POST'}).then(r=>r.json()).then(ch=>navigator.credentials.get({publicKey:ch}))

Developer tips

  • Bind keys to your site origin to prevent key reuse.
  • Require explicit user confirmation for every signing operation.
  • Provide clear recovery instructions and allow secondary sign-in methods.

FAQ

Do I still need my recovery phrase?

Yes. The recovery phrase is the ultimate backup for your keys and must be stored carefully offline. Ledger Login reduces exposure during everyday use but does not replace the need for a secure backup.

Can sites track me across services?

No. Ledger Login issues unique keys per site/origin, preventing cross-site tracking based on authentication keys.

What if I lose my device?

Use your recovery phrase to restore keys on a new Ledger device. Services may also let you add secondary sign-in methods for recovery convenience.
