What Auth0 is
Auth0 is a service for developers implementing user authentication in web, mobile, and agentic applications. It supports authentication across applications, including single sign-on, for teams that need to manage how users access their products.
Developers can use Auth0’s hosted Universal Login flows or build embedded login through its APIs, SDKs, and components. It supports username and password login, social identities, enterprise single sign-on, passwordless options, biometrics, and passkeys.
