Identity & Access Management

3 Best Auth0 Alternatives in 2026

Auth0 is a developer-focused customer identity platform (CIAM) now owned by Okta but sold as a separate product. It provides drop-in login, social sign-in, passwordless authentication, and multi-factor auth for applications, with SDKs for nearly every major framework. Auth0 is especially popular with SaaS startups because of its generous free tier and developer experience: you can go from zero to a working login flow in minutes.
