OAuth2

The Client Credentials Flow is a foundational grant type in OAuth 2.0, designed for machine-to-machine (M2M) communication scenarios where no end-user is involved. This flow enables secure backend services, daemons, or microservices to authenticate themselves and access protected APIs without user interaction. 🔍 When Should You Use the Client Credentials Flow? Use this flow when: A backend service needs to call another internal API A scheduled job or daemon interacts with protected endpoints Microservices need to exchange data without involving users You’re building automated scripts or monitoring tools that access APIs 🔐 How the Flow Works (Step-by-Step) Here’s how the Client Credentials Flow operates: ...

OAuth2 has become the de facto standard for authorization in modern web applications, and ForgeRock Access Management (AM) is a leading platform for implementing OAuth2-based solutions. In this article, we will dive deep into OAuth2, explore its architecture, and demonstrate how it integrates with ForgeRock AM. What is OAuth2? OAuth2 is an authorization framework that enables third-party applications to access user resources without sharing credentials. It is widely used for scenarios like single sign-on (SSO), delegated access, and API protection. OAuth2 operates on the principle of “tokens,” which are used to grant access to protected resources. ...

Security Assertion Markup Language (SAML) is an XML-based open standard used for exchanging authentication and authorization data between different security domains. SAML is most commonly used in Single Sign-On (SSO) scenarios, allowing users to access multiple applications or services without the need to log in repeatedly. It has become a critical technology for enabling secure identity management across web-based applications, particularly in enterprise environments and cloud services. What Are Identity Providers (IdP) and Service Providers (SP)? In the context of SAML, there are two primary roles: ...
