OAuth 2.0 provides a more secure model than API keys for machine-to-machine communication. Learn why.

Auth0's platform is a  identity management solution, offering insights into authentication, authorization, and user management for web and mobile applications. Through articles, tutorials, and documentation, Auth0 offers insights into securing applications with modern identity protocols like OAuth and OpenID Connect. Developers can learn about implementing single sign-on (SSO), multi-factor authentication (MFA), and user authorization policies to enhance application security and user experience.

Learn about the advantages of migrating to OAuth 2.0 from API keys. OAuth 2.0 provides improved security, flexibility, and developer experience compared to static API tokens. It mitigates risks associated with API keys such as unauthorized access, difficulties in key rotation, limited scope, inherited permissions, auditing challenges, and brittleness. OAuth 2.0 offers support for service-to-service interaction, task-based automation, and user access through a web application. The migration process involves ensuring API support for OAuth 2.0, generating public/private key pairs, configuring private key JWT authentication, requesting access tokens, adding access tokens to API requests, and incorporating OAuth into the application system. Best practices include implementing new API calls using OAuth 2.0 and following the principle of least privilege.
