Where Passwordless Becomes Enforceable

Smart contracts introduce consequence to authentication — and redefine what identity security can do.

AuthLN combines device-bound FIDO2 passkeys with smart contract–enforced authentication to transform login attempts into contract-governed events.

Device-Paired Authentication (FIDO2 Passkey)

AuthLN leverages FIDO2 passkey architecture to bind authentication to a specific physical device. Each credential is generated and stored inside the device’s secure hardware enclave, preventing credential reuse, phishing replay, or remote impersonation.

How It Secures Access

  • Device-bound cryptographic keys

    Private keys are generated and stored inside the device TPM / Secure Enclave and never leave the hardware boundary.

  • No passwords to steal or replay

    There is no shared secret transmitted over the network. Authentication requires possession of the registered device.

  • Origin-bound assertions

    FIDO2 ensures credentials are cryptographically scoped to the legitimate relying party, eliminating phishing reuse.

  • Hardware-backed protection

    Works natively with Microsoft, Apple, and Android TPM / Secure Enclave implementations.

Smart Contract–Enforced Authentication

AuthLN places a programmable Cryptographic-based smart contract in front of protected resources. Every login attempt must satisfy that contract before access is evaluated.

AuthLN treats access attempts as contract-governed events:

  • Authorized users satisfy the contract with cryptographic proof.

  • Unauthorized actors must satisfy it with capital.

How Works:

  • Device-bound FIDO2 passkeys act as payment

    A valid hardware-backed passkey assertion satisfies the smart contract requirement without monetary transfer.

  • No shared secrets, no reusable credentials

    The passkey proves possession of the paired device and clears the contract condition instantly.

  • Unauthorized attempts require economic commitment

    If a valid passkey is not presented, the contract requires a Lightning Network micropayment to proceed.

  • Automation becomes economically bounded

    Credential stuffing, brute force, and AI-driven probing can continue — but each attempt now carries enforceable cost.

  • Policy-controlled enforcement

    Organizations can define when cryptographic proof is sufficient and when economic commitment is required.

Your IdP remains the authority. AuthLN becomes the enforcement layer.

AuthLN integrates directly with your existing identity provider, adding device-paired authentication and economic enforcement without disrupting current workflows.

  • Full OAuth 2.0 support

  • SAML 2.0 integration

  • Works with Okta, Microsoft Entra ID, Google, and Ping

  • Guided setup wizards for rapid onboarding

  • No directory migration or credential duplication

  • Overlay deterrence on existing MFA and Conditional Access

Every Event Becomes Signal

AuthLN captures every contract-governed authentication attempt — whether satisfied by cryptographic proof or economic commitment.

When access attempts carry consequence, security teams gain clarity.

  • Traditional systems generate logs.

  • AuthLN generates signal.

There are no silent probes. No anonymous retries. No discarded noise.

  • Every login attempt is recorded as an attributable event

  • Failed smart contract conditions generate high-confidence signal

  • Economic commitment amplifies intent detection

  • Eliminates background authentication noise

  • Transforms attack traffic into measurable telemetry

Pre-Breach Intrusion Alerts

AuthLN monitors every contract-governed authentication attempt. When a login attempt fails to satisfy the required cryptographic or economic commitment, your security team is alerted — before access is evaluated, before a session is created, and before your system is touched.

This is signal before breach — not incident response after damage.

  • Alerts triggered when required smart contract conditions are not met

  • Detects probing, automation, and incomplete payment attempts

  • No need to wait for account lockouts or MFA fatigue signals

  • Actionable telemetry tied to economically bounded events

A New Identity Factor

Authentication is no longer just what you know or what you have. It is what you commit.

AuthLN introduces an enforceable identity factor based on commitment.

  • Authorized users satisfy the contract with a FIDO2 passkey

  • Unauthorized actors must satisfy it with capital

  • Every attempt becomes attributable and economically bounded

  • Risk signals are amplified when attackers are forced to commit value
