Auth0 Identity Platform

Auth0 is a cloud-based identity and access management (IAM) platform providing authentication, authorization, and user management as a service. Founded in 2013 by Eugenio Pace (CEO, former Microsoft patterns and practices team) and Matias Woloski (CTO) in Bellevue, Washington, the company was acquired by Okta in May 2021 for $6.5 billion. The platform serves over 10,000 customers including Atlassian, Siemens, AMD, and Twitch, processing billions of logins monthly. Key features: universal login: a centralized, customizable login page handling all authentication flows. Support for username and password, social login (Google, Facebook, Apple, Microsoft, GitHub), enterprise login (SAML, LDAP, Active Directory), passwordless (email, SMS, biometric), and multi-factor authentication (TOTP, push notifications, SMS). Single Sign-On (SSO): once authenticated, users access all connected applications without re-entering credentials. Supports SAML 2.0, OIDC (OpenID Connect), and CAS protocols. Social connections: pre-built integrations with over 30 social identity providers. Enterprise connections: integrate with Azure AD, Google Workspace, Active Directory, LDAP, and SAML providers. API authorization: OAuth 2.0 compliant token issuance. Role-Based Access Control with permissions, roles, and groups. Actions: Node.js-based custom logic functions that execute during the authentication pipeline, with npm package support for external API calls, custom claims, and security checks. User management: profiles, metadata, password policies, account linking, and anomaly detection. Branding: customizable login pages, emails, and domains. Security: breach password detection, brute-force protection, suspicious IP throttling, and bot detection. SDKs for over 20 platforms. Node.js/.NET. Proprietary.
