What Auth0 does
Auth0 is a cloud Customer Identity and Access Management (CIAM) platform that provides authentication, authorization, and user management for web, mobile, IoT, and internal applications. Founded in 2013 and headquartered in Bellevue, Washington, Auth0 has been a wholly-owned subsidiary of Okta, Inc. since Okta's approximately $6.5 billion stock acquisition in 2021. The platform is built on a developer-first architecture with 30+ SDKs and quickstarts spanning React, Angular, Next.js, iOS, Android, Java, .NET, Python and others, supporting OpenID Connect, OAuth 2.0/2.1, SAML 2.0, and WebAuthn/FIDO2 standards. Core capabilities include Universal Login (hosted authentication), Embedded Login (in-app authentication), Single Sign-On, Multi-Factor Authentication (including adaptive MFA), Machine-to-Machine authentication, Passwordless options, Breached Password Detection, Fine-Grained Authorization built on the OpenFGA CNCF project, and a serverless Actions extensibility layer.
Auth0 operates a hybrid go-to-market combining a free self-serve tier and a Startup Program (offering free B2B Professional plans to eligible startups for one year) with a field sales team that closes enterprise deployments. Revenue is generated primarily through subscription pricing based on Monthly Active Users, with enterprise contracts reportedly ranging from $15,000 to $30,000 per month and add-ons of $1,500 to $6,000 per enterprise SSO connection per month. The platform processes over 10 billion authentications and blocks more than 3 billion attacks per month with a 99.99% uptime SLA, and serves a diverse named customer base including Siemens, Signify (Philips Hue), McLaren Racing, PGA of America, Zapier, Jersey Mike's, Cribl, City of Los Angeles, Wyndham Hotels & Resorts, Snyk, and Arduino.
In 2026 Auth0 executed a strategic pivot toward AI agent identity with the general availability of Auth0 for AI Agents, Auth for MCP, Fine-Grained Authorization for RAG, and Token Vault. The platform has secured major infrastructure partnerships for this initiative with AWS (Amazon Bedrock AgentCore), IBM (watsonx.ai), Yubico, Akamai, Cloudflare, Visa, and several AI agent frameworks including LangChain, LlamaIndex, Vercel AI SDK, and Firebase Genkit. Auth0 maintains SOC 2 Type II, ISO 27001, GDPR, CCPA, HIPAA, PCI DSS, and WCAG AA compliance.

Auth0 competitors and assessment
Company assessmentBroad incumbents
- AWS Cognito: AWS Cognito is the hyperscaler-bundled CIAM service integrated with the broader AWS stack. It competes with Auth0 on price and cloud-consolidation, particularly for B2C and AWS-native deployments.
- Microsoft Entra External ID: Microsoft's customer identity offering (formerly Azure AD B2C) provides SSO, MFA, and identity for consumer apps inside the Microsoft cloud ecosystem. It is a frequent substitute for Auth0 in Microsoft-centric enterprises.
- Google Cloud Identity / Firebase Authentication: Firebase Authentication and Google Cloud Identity provide identity services to Google Cloud and Firebase ecosystems. They overlap with Auth0 on social login, MFA, and B2C authentication, often preferred for Google-centric stacks.
Direct peers
- WorkOS: WorkOS provides enterprise-ready authentication (SSO, SCIM, directory sync) and is the most direct B2B SaaS-focused competitor to Auth0, targeting the same developer-first, enterprise-up motion with a modern API.
- Ping Identity: Ping Identity is a longstanding IAM platform covering both workforce and customer identity. Auth0 was cited as a direct partner alongside Ping in Akamai's agentic security framework, confirming category overlap.
- Stytch: Stytch offers authentication and identity APIs (passwordless, MFA, B2B SSO, organizations) targeting developers and AI-era applications. It competes head-on with Auth0 for the next generation of identity stacks.
- Clerk: Clerk provides drop-in authentication, user management, and organizations for modern web and mobile apps. It targets the same developer-first PLG segment as Auth0 with strong framework-native SDKs.
- Descope: Descope focuses on CIAM and AI-agent authentication flows, positioning directly against Auth0 for AI Agents with a developer-first drag-and-drop approach to identity workflows.
Emerging players
- Keycloak: Keycloak is an open-source IAM solution from the CNCF, often deployed by organizations seeking to avoid vendor lock-in to Auth0. It provides SSO, identity brokering, and user federation comparable in feature set.
- Kinde: Kinde is a developer-focused CIAM platform offering auth, organizations, and billing primitives for modern SaaS. It targets the same PLG funnel as Auth0 with a younger, more transparent pricing model.
