## About

Auth0 is a developer-focused identity and authentication platform founded in 2013 by Eugenio Pace and Matías Woloski in Bellevue, Washington. The platform provides authentication, authorization, and user management for web and mobile applications through SDKs and APIs, allowing developers to add login (social, passwordless, MFA, SSO) without building it from scratch. Okta acquired Auth0 in 2021 for $6.5B and now markets it as the Okta Customer Identity Cloud (CIAM) — distinct from Okta Workforce Identity. Auth0 remains developer-first with its own SDKs and documentation. The platform is used by over 18,000 organizations including Siemens, Pfizer, and Bloomberg.

## What reviewers say

_~800 G2 and Capterra reviews, 2025-2026_

**Praised:**
- Best documentation of any authentication platform; Quickstarts actually work
- Social login (Google, GitHub, Apple, etc.) takes 30 minutes to add
- Organizations feature handles B2B multi-tenancy cleanly
- Free tier is genuinely useful for production apps under 25K users

**Complaints:**
- Pricing scales steeply beyond the free tier; large user bases are expensive
- Post-Okta acquisition, some users report slower feature development
- Actions (custom logic) has performance overhead vs. self-managed solutions

## Compliance

- **SOC 2:** Yes (Type II)
- **GDPR:** Yes
- **HIPAA:** Yes (paid plans with BAA)
- **SSO:** Yes (machine-to-machine and enterprise SSO)

## Integrations

- AWS
- Azure

## FAQs

### Is Auth0 the same as Okta?

Auth0 is now the Okta Customer Identity Cloud (CIAM), focused on adding authentication to applications. Okta Workforce Identity is the separate enterprise SSO product for employees. Same parent company, different products for different use cases.

### How does Auth0 compare to AWS Cognito?

Auth0 has significantly better developer experience, documentation, and social login support. Cognito is cheaper at scale and integrates natively with AWS services. If you're AWS-native, Cognito can work; otherwise Auth0's DX wins.
