OpenID Connect (OIDC) is an authentication protocol that is built on top of the OAuth 2.0 authorization framework. It enables users to authenticate with a third-party identity provider (IdP) and obtain an access token that can be used to access protected resources, such as web APIs or applications.
Here are some of the things that OpenID Connect can do:
- Authentication: OIDC provides a mechanism for user authentication, enabling users to sign in to applications using their existing accounts with third-party identity providers.
- Authorization: OIDC enables applications to request access to protected resources on behalf of users and obtain authorization to access those resources.
- Single Sign-On (SSO): OIDC enables users to authenticate once with their identity provider and obtain a token that can be used to access multiple applications without having to re-authenticate.
- User Profile Information: OIDC enables applications to obtain user profile information, such as name and email address, from the identity provider, which can be used to personalize the user experience.
- Standardization: OIDC is a standard authentication protocol that is widely adopted across the industry, making it easier for applications to integrate with different identity providers and for users to switch between providers.
Overall, OpenID Connect is a flexible and secure authentication protocol that enables users to authenticate with third-party identity providers and access protected resources. It simplifies the process of user authentication and authorization, making it easier for developers to build secure and scalable applications.
