What is Oauth And Openid Connect - Startup House

OAuth (Open Authorization) is an open standard for access delegation, commonly used as a way for internet users to grant websites or applications access to their information on other websites without sharing their passwords. OAuth allows users to grant third-party access to their resources stored on a server, such as profile information, photos, or documents, without revealing their credentials. It provides a secure and standardized way for websites and applications to access user data without needing to store sensitive information like passwords.

OpenID Connect is an authentication protocol built on top of OAuth 2.0, which allows clients to verify the identity of the end-user based on the authentication performed by an authorization server, as well as to obtain basic profile information about the end-user in an interoperable and REST-like manner. OpenID Connect provides a simple identity layer on top of OAuth 2.0, allowing clients to verify the identity of the end-user based on the authentication performed by an authorization server.

In summary, OAuth is primarily used for authorization, allowing third-party applications to access user data without needing to store passwords, while OpenID Connect is used for authentication, allowing clients to verify the identity of the end-user based on the authentication performed by an authorization server. Together, OAuth and OpenID Connect provide a secure and standardized way for websites and applications to access user data and verify user identities without compromising security.
