What this API does
The Auth0 Authentication API provides a comprehensive suite of authentication and authorization services tailored for modern web and mobile applications. It supports diverse login methods such as username/password, passwordless email or SMS, and extensive social login options including Google, Facebook, and GitHub. Integrating Single Sign-On (SSO) allows enterprises to centralize user access across multiple applications effortlessly. Multi-Factor Authentication (MFA) enhances security by requiring additional verification steps. The API adheres strictly to OAuth 2.0 and OpenID Connect standards, ensuring secure token issuance and validation with seamless SDK support for platforms like JavaScript, iOS, Android, and .NET.
How it works
To use the Auth0 API, developers send HTTP requests to various endpoints to manage authentication workflows. This includes obtaining tokens for authentication, managing user accounts, and integrating social login capabilities. It employs secure HTTPS protocols for all transactions to safeguard user data and ensure compliance with industry standards.
Developers can leverage SDKs to facilitate integration across different platforms, enabling them to customize user management flows while maintaining compliance and scalability.
Authentication
Authentication is primarily handled via API tokens. Developers must register their applications on the Auth0 dashboard to obtain a Client ID and Client Secret, used to generate access tokens for API interactions. The API supports authentication flows including authorization code flow, implicit flow, and client credentials flow, ensuring flexibility for various application needs.
Example usage
