Features

Passkeys / WebAuthn

Biometrics and device-based sign-in. No passwords to remember or leak.

Drop-in SDK

npm install, 5 lines of code. Integrate in minutes, not days.

Multi-tenant

B2B ready with tenant isolation. One dashboard, many apps.

Email Fallback

OTP when WebAuthn isn't available. Seamless fallback for all users.

Event System

Hooks for spinners, analytics, and custom UX on every step.

Type-safe

Full TypeScript, Result pattern. No surprise runtime errors.

See it in code

Drop-in SDK. Same pattern for registration and sign-in.

const result = await client.register({ /* options */ });
if (result.isOk()) { 
  const { session_token } = result.value;
  // Send to your backend to set cookie
