AAbout Auth0
Auth0 is an identity-as-a-service platform that handles authentication and authorization so developers don't have to build login systems from scratch. It supports a wide range of identity protocols including OAuth 2.0, OpenID Connect, and SAML, along with social logins, multi-factor authentication, and passwordless options. Acquired by Okta in 2021, it's particularly popular among developers for its extensive documentation, SDKs for nearly every major language and framework, and flexible extensibility through custom rules and actions. It serves everyone from startups needing a quick login solution to enterprises managing complex identity requirements across multiple applications.
