Authsignal

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.
