  Authsignal is a passwordless, step-up, and risk-based authentication
  platform. The product wraps passkeys, authenticator apps (TOTP), SMS and
  WhatsApp OTP, email OTP and magic links, push notifications, biometrics
  (face / palm), and ID verification behind a unified Server API, Client API,
  and Management API. A no-code rules engine routes high-risk events through
  step-up challenges, and audit / observability surfaces every authentication
  attempt. Authsignal slots in front of existing identity providers
  (Cognito, Auth0, Azure AD B2C, Keycloak, IdentityServer, NextAuth.js) or
  works standalone.
