Auth0
Identity platform (by Okta) covering login, social and enterprise connections, MFA and B2B features.
Works with AI agents:llms.txtMCPAuth0, owned by Okta, is a hosted identity platform for customer-facing apps. It handles login with passwords, passwordless codes, social providers and enterprise identity providers, plus MFA, user storage and access tokens for your APIs.
Everything lives in a tenant: a named configuration space that holds your applications, connections (the ways users can log in) and user profiles, usually with separate tenants for development, staging and production. The recommended flow is Universal Login: your app redirects to a login page Auth0 hosts, the user authenticates there, and your app receives standard OAuth 2.0 / OpenID Connect tokens back. You customize behavior with Actions, versioned Node.js functions that run at points such as pre-registration or post-login. Quickstarts cover Next.js, React, Vue, Angular, Svelte, Express, Fastify, Hono, Django, FastAPI, Rails, Laravel, Go, Java, .NET, iOS, Android, Flutter and React Native.
For a small team the practical pieces are Organizations for B2B tenants, enterprise connections with SAML and SCIM, account linking, breached-password detection and attack protection, and bulk user import and export. The public cloud is multi-tenant on AWS with regions in the US, UK, Europe, Australia, Japan and Canada; dedicated private cloud on AWS or Azure is an Enterprise option.
The model has many moving parts (tenants, connections, Actions, Management API tokens), which is more to learn than a drop-in component kit. Rate limits depend on your plan and tenant type, and dedicated infrastructure is reserved for Enterprise contracts.

Questions makers ask about Auth0
Which frameworks does Auth0 have quickstarts for?
Web apps in Next.js, Nuxt, React Router, Express, Fastify, Hono, Django, FastAPI, Python, Rails, Laravel, PHP, Go, Java and ASP.NET; SPAs in React, Vue, Angular and Svelte; and native apps on iOS, Android, Flutter, React Native and Expo. source ↗
Where can my tenant's data be hosted?
On the multi-tenant public cloud you choose a region in the United States, United Kingdom, Europe, Australia, Japan or Canada. Private cloud deployments on AWS or Azure, available on Enterprise plans, offer more regions and a dedicated instance. source ↗
Which compliance certifications does Auth0 hold?
Auth0 is audited annually for SOC 2 Type 2 and ISO 27001/27017/27018, is CSA STAR certified, and describes itself as GDPR ready. It can sign a HIPAA Business Associate Agreement on request, though HIPAA is not available on Azure deployments. Reports are requested through the Auth0 Support Center. source ↗
Can I export my users, including password hashes?
Yes. You can bulk export user profiles as NDJSON or CSV from the dashboard or the Management API. Password hashes and MFA secrets are a separate request, delivered encrypted with a PGP key you provide. source ↗
How do I move existing users to Auth0 without forcing password resets?
Either bulk import them with hashes from a supported algorithm (each import file is capped at 500KB, roughly 1,000 users), or use automatic trickle migration through a custom database connection, which moves each user over the first time they log in. source ↗
Is there an uptime SLA?
Auth0 states a 99.99% availability commitment for both its public and private cloud deployments. source ↗
How do I add custom logic to the login flow?
With Actions: versioned Node.js functions attached to triggers such as pre-user-registration or post-login, which can call external services and use npm packages. They replace the older Rules and Hooks. source ↗
Is Auth0 free?
Yes — there is a free tier a small product can run on; paid use starts at $35/mo. source ↗
Is Auth0 open source or self-hostable?
Not open source, and hosted only.
Can AI coding agents work with Auth0?
It serves an llms.txt docs index; it has an official MCP server (com.auth0/mcp).
