As businesses and individuals continue to use more applications and services, the need for secure and seamless authentication becomes increasingly important. Single sign-on (SSO) is a solution that addresses this issue by allowing users to access multiple applications with just one set of credentials. In this article, we will explore SSO in detail, including its authentication methods, how it works, and the role of OpenID Connect and OAuth 2.0 API in enabling SSO authentication.
Authentication Tokens and Their Importance
Authentication tokens are a type of security token that allows users to access resources without having to repeatedly enter their credentials. They are used to authenticate user identities and grant access to protected resources. Authentication tokens can be implemented in various forms, such as session cookies, JSON Web Tokens (JWT), and Security Assertion Markup Language (SAML) assertions.
OpenID Connect & OAuth 2.0 API
Both OpenID Connect and OAuth 2.0 are widely used in modern web applications to provide secure access control and authentication mechanisms. OpenID Connect extends OAuth 2.0 by adding an identity layer, allowing it to be used for more than just authorization. It provides a standardized way to perform user authentication and enables clients to obtain information about the authenticated user. In contrast, OAuth 2.0 is a protocol for granting access not only to end-user resources but also to machine-to-machine interactions.
OpenID Connect is designed to be user-centric, enabling users to authenticate with an identity provider and securely share their personal data with third-party applications without having to create new accounts or manually enter their credentials. OAuth 2.0 has become widely adopted as the standard for API authorization because of its adaptability and simplicity, enabling developers to implement SSO (Single Sign-On) and federated identity management across various applications with ease. This adoption has made
OAuth 2.0 the go-to choice for developers seeking to streamline their authorization processes while maintaining a high degree of security. It allows service providers to issue access tokens to third-party applications that can then use these tokens to access protected resources on behalf of the user. This means that users can grant access to their resources to third-party applications without directly sharing their login credentials with the application. Applications can request access to resources using OAuth 2.0 scopes, which define the level of access the application is requesting.
In summary, OpenID Connect and OAuth 2.0 are powerful protocols that enable secure and efficient access control and authentication mechanisms for modern web applications. While they have some similarities, they serve different purposes and can be used together to provide comprehensive identity and access management solutions.
A Comparative Analysis of Single Sign-On Technologies used by Google
OIDC or OpenID Connect is an uncomplicated identity layer which functions on the OAuth 2.0 protocol. Its main purpose is to authenticate end-users through an authorization server and acquire fundamental user profile information. It is predominantly utilized for Single Sign-On (SSO) scenarios, enabling clients to validate user identity and grant access to multiple applications without having to log in repeatedly. OAuth 2.0 is a framework for authorization that allows a third-party application to gain restricted access to an HTTP-based service. The level of access granted is limited, ensuring that only the necessary permissions are provided to the application and ensuring security for the user. This can be achieved by either allowing the application to access the service on its own or by acting on behalf of a resource owner. The primary function of OAuth 2.0 is to enable users to grant access to their account information without the need to disclose their login credentials such as username and password. This feature enhances security while still allowing third-party applications to access user data with limited permissions. When using SSO with Google, the IdP (Identity Provider) is responsible for verifying user identities and issuing tokens. In this case, Google acts as the IdP. When a user attempts to access a Google service, they are directed to Google’s login page where they must input their login details. After the credentials are verified, Google generates a token that can be used to authenticate future requests. The SP (Service Provider) consumes the tokens issued by the IdP to grant access to users. A typical example of an SP is a web application that requires users to log in before accessing protected resources. The SP trusts the IdP to authenticate users and relies on the tokens issued by the IdP to grant access to protected resources. The user store is where user credentials are stored, allowing the IdP to verify user identities. In the case of Google, the user store is managed by Google itself. When a user creates a Google account, their credentials are stored securely by Google. When the user logs in to a Google service, Google verifies their credentials against the stored information in the user store.
