What is Auth0?
Auth0 is a cloud identity and access management platform (now part of Okta) that lets developers add secure login, authentication and authorization to their apps without building it themselves. It handles the genuinely hard, security-critical work of managing user identity — and does it at massive scale, processing 23 billion+ authentications every month.
What Auth0 is
Auth0 provides the building blocks of identity for web, mobile and now AI-agent applications: passwordless and social login, adaptive multi-factor authentication, a customizable Universal Login, fine-grained authorization, machine-to-machine auth, and enterprise features like SSO, SAML and SCIM. Developers integrate it via 30+ SDKs, often in minutes, rather than spending months building auth from scratch.
Who it's for
Auth0 serves B2C companies needing customer login and fraud prevention, B2B SaaS platforms requiring enterprise SSO and multi-tenancy, AI developers building agentic applications, and enterprises across retail, finance, healthcare, manufacturing and tech. Essentially any team that needs robust, secure identity but would rather not build and maintain it in-house is a fit.
What it offers
- Passwordless, social and embedded login, plus Universal Login
- Adaptive multi-factor authentication
- Fine-grained authorization (FGA) and role-based access
- Machine-to-machine auth and Token Vault for credentials
- Organizations and multi-tenancy support
- Agent identity, MCP authentication and async authorization for AI
- Enterprise SSO, SAML, OIDC and SCIM provisioning
- 30+ SDKs (React, Next.js, Angular, Vue, iOS, React Native)
Don't build auth yourself
Authentication is deceptively hard and dangerous to get wrong, and Auth0's core value is taking it off your plate. Instead of building login, password handling, MFA and session security — and risking a costly mistake — you integrate Auth0 and get battle-tested identity in minutes. For development teams, that means shipping faster and more securely, letting specialists who focus entirely on identity handle the part where a single vulnerability can be catastrophic.
Security proven at scale
Auth0 operates at a scale few can match: 23 billion+ authentications a month with 99.99% uptime, and (across the Okta/Auth0 platform) 3 billion+ attacks blocked monthly. That scale is itself a security advantage — adaptive MFA and fraud detection learn from an enormous volume of traffic to spot and stop attacks. For any app handling user accounts, riding on infrastructure that already defends against billions of attacks is far safer than going it alone.
Identity for AI agents
Auth0 has moved early into securing AI applications, an emerging and tricky area. It offers agent identity verification through SDKs, Model Context Protocol (MCP) authentication, asynchronous authorization for agents, and access control for RAG data sources — so autonomous agents can act with proper, auditable permissions rather than unchecked access. As AI agents start taking real actions, having identity built for them (not just for humans) is increasingly essential.
Serves both consumers and enterprises
Auth0 handles two quite different identity worlds from one platform. For consumer (B2C) apps it offers smooth social and passwordless login plus fraud prevention to keep sign-up friction low and accounts safe; for B2B SaaS it provides the enterprise SSO, SAML, SCIM provisioning and multi-tenancy that business customers demand. That range means a company can start with simple customer login and, as it lands enterprise deals requiring single sign-on, meet those needs without re-platforming its identity — a flexibility that's saved many growing SaaS companies a painful migration.
Why choose Auth0
For developers and companies that need secure, scalable identity without building it themselves, Auth0 is a market-leading choice. Its comprehensive authentication and authorization, enterprise SSO and provisioning, proven security at massive scale, emerging AI-agent identity features, and excellent developer experience with 30+ SDKs make it a practical way to add login and access control to any application — quickly, and with the confidence that comes from infrastructure trusted at global scale.
What is SuperTokens?
SuperTokens is an open-source authentication and session-management platform — a developer-friendly alternative to services like Auth0 and AWS Cognito. You can self-host it for full control or use the managed service, and either way you get customizable login, secure sessions and no vendor lock-in, across more than 25 frameworks.
What is SuperTokens?
SuperTokens handles the hard, security-critical parts of user auth so you don't have to build them from scratch: sign-up and login, session management, password policies and more. Its distinctive architecture separates a backend core from frontend SDKs, which gives developers far more room to customize flows and keep data under their control than a typical closed auth service allows.
Who it's for
SuperTokens is built for developers and teams — startups and enterprises alike — who want customizable authentication without being locked into a proprietary vendor. It's especially appealing to organizations that prefer open source, want to self-host for data ownership, or need to control auth costs as they scale. SDKs cover JavaScript, React, Angular, Vue, Python, Go, Flutter, Android, iOS and more.
Key features
- Multiple auth methods: email/password, passwordless magic links, social login and SSO
- Robust session management with custom password policies and session limits
- Multi-tenancy support with tenant discovery
- Account linking across different sign-in methods
- Attack Protection Suite with CAPTCHA integration and bot prevention
- Pre-built UI deployable in minutes, or fully custom interfaces
- Plugin system for extensibility (banning, CAPTCHA, tenant discovery)
Own your auth and your data
The biggest reason teams pick SuperTokens is control. Self-hosting means users authenticate on your own domain with no redirects to a third party, and you keep full ownership of the user data — a sharp contrast to hosted auth services. The core-plus-SDK architecture also means you can customize login flows deeply instead of bending your product around a vendor's fixed UI.
Fast to set up, deep when you need it
Despite that flexibility, SuperTokens is quick to get running: a pre-built UI can be live in about five minutes via the CLI, and 25+ framework SDKs mean it drops into most stacks. When you need more, the plugin system and customizable interfaces let you extend it — from banning users to adding CAPTCHA to building bespoke tenant discovery — so it grows with your requirements rather than capping them.
Trusted and cost-conscious
SuperTokens is Y Combinator-backed, SOC 2 compliant and has 12,000+ GitHub stars, reflecting real community trust. It also emphasizes cost savings versus commercial competitors and offers seamless migration from Auth0 without forcing password resets — so teams outgrowing a pricey hosted service can switch without disrupting their users.
Security built in, not bolted on
Authentication is where security matters most, and SuperTokens treats it that way. Its Attack Protection Suite adds CAPTCHA integration and bot prevention to defend against credential stuffing and automated abuse, robust session management guards against hijacking, and custom password policies and session limits give teams fine control over risk. Because the flows are open source, security-conscious teams can also audit exactly how their auth works rather than trusting a black box.
Why choose SuperTokens
For developers who want secure, customizable authentication without vendor lock-in or ballooning costs, SuperTokens is a compelling open-source option. Its self-hosting, flexible architecture, broad framework support, attack protection and easy migration make it a practical way to own your login stack while keeping setup fast and your users' data in your hands.
