Description: OpenID Connect (OIDC) is an authentication protocol built on top of the OAuth 2.0 authorization framework. Its main goal is to allow clients to securely and easily verify the identity of end users. OIDC provides an additional layer that enables applications to obtain basic information about the user, such as their name and email address, through an ‘ID Token’. This token is a JSON Web Token (JWT) that contains information about the authentication and user attributes. OIDC is particularly relevant in the context of web and mobile applications, where user experience is crucial. By allowing users to log in using credentials from trusted identity providers (such as Google, Facebook, or Microsoft), OIDC simplifies the authentication process and enhances security by reducing the need to manage multiple passwords. Additionally, OIDC is compatible with most programming languages and platforms, making it a versatile option for developers looking to implement authentication in their applications. In summary, OpenID Connect is a modern and efficient solution for identity and access management, facilitating user authentication in an increasingly complex digital environment.
History: OpenID Connect was developed by the OpenID Foundation and officially launched in 2014. Its creation was driven by the need for an authentication protocol that could effectively operate over OAuth 2.0, which was already widely used for authorization. Prior to OIDC, OpenID existed as a standalone protocol but lacked certain security features and ease of use that were required in the current environment of web and mobile applications. The evolution of OIDC has been marked by increasing adoption by companies and developers, becoming a de facto standard for online authentication.
Uses: OpenID Connect is primarily used for user authentication in web and mobile applications. It allows developers to implement a single sign-on (SSO) system, where users can access multiple applications using a single account from an identity provider. This not only enhances user experience but also reduces the burden of password management. Additionally, OIDC is used in various environments to integrate internal and external applications, facilitating access management and security.
Examples: A practical example of OpenID Connect is the login process in various applications, where users can authenticate using their accounts from trusted identity providers. Another case is the use of OIDC in online education platforms, where users can access multiple resources using a single account from an identity provider. Additionally, many organizations use OIDC to allow their employees to securely and efficiently log into applications.
