AuthLN Mobile App

AuthLN Pay Factor Authentication (PFA) is a FIDO2 passkey-based login system enhanced with an economic safeguard.

AuthLN — Passkey Authentication with a Cost to Attackers

AuthLN is a passkey authenticator that makes identity spoofing economically irrational. Real users sign in seamlessly with a device‑bound passkey. Anyone trying to impersonate them must commit real economic value through a Lightning‑backed invoice — turning identity attacks into a financial risk.

What you can do in the app

• Sign in and approve logins with a device‑bound passkey — no passwords, no MFA fatigue
• Use AuthLN as your system‑wide passkey provider — autofill passkeys across your other apps and browsers
• Approve a login on the same device straight from a push notification
• Add and manage multiple devices, and enroll a new phone from one you already trust
• Keep multiple accounts on a shared device
• Recover access with passkey sign‑in or a backup code if you lose your device
• Available in English, Spanish, French, and German

Why AuthLN is different

1. Make attackers think twice. Credential stuffing, brute force, and phishing rely on volume. AuthLN removes the volume advantage — every attempt carries a cost.
2. Fewer alerts, better signals. When an attacker is willing to pay to try, that signal matters. You cut noise and surface high‑confidence events instead of endless false positives.
3. Stronger Zero Trust. AuthLN adds an economic factor to identity — not just "who are you?" but "are you willing to risk value?"
4. Seamless for real users. Authorized users authenticate with a device‑bound passkey. No extra friction. No endless push prompts.
5. Works with what you already have. AuthLN layers onto your existing identity stack — including Microsoft Entra, Okta, Ping, and Google. No rip‑and‑replace.
