Authentication

Single Sign-On (SSO) using SAML (Security Assertion Markup Language) simplifies user authentication by allowing seamless access to multiple applications with a single login. ForgeRock, a leading identity and access management (IAM) platform, provides robust support for SAML-based SSO. This guide covers configuring ForgeRock as an Identity Provider (IdP), uploading Service Provider (SP) metadata, selecting the appropriate NameID format, and demonstrating the authentication flow with HTTP Archive (HAR) captures. 1. Provider Configuration ForgeRock as an Identity Provider (IdP) To set up ForgeRock as an IdP for SAML SSO: ...

Security Assertion Markup Language (SAML) is a cornerstone protocol in modern federated identity and Single Sign-On (SSO) architectures. While it greatly simplifies the login experience for users, debugging issues with SAML responses can be complex due to cryptographic signatures, strict protocol compliance, and encoding formats. This blog post walks through essential techniques to effectively debug and troubleshoot SAML responses, along with recommended tools and common errors. 🛠️ Recommended Tools for Decoding SAML Responses To debug a SAML authentication issue, you must first be able to inspect the raw SAML response. Here are two essential tools every engineer should have: ...

OAuth 2.0 is a widely used authorization framework that enables applications to access user data on behalf of the user without requiring the user to share their credentials. It provides a secure and standardized approach to delegating access control, ensuring that applications can interact with various services while keeping user information private. The Authorization Code Flow is one of the core grant types in OAuth 2.0, designed for scenarios where both the client and the authorization server need to exchange information securely. ...

OAuth 2.0 is a widely used authorization framework that allows applications to obtain limited access to user resources without handling user credentials directly. The Authorization Code Flow with PKCE (Proof Key for Code Exchange) is a security-enhanced version of the Authorization Code Flow, specifically designed to address vulnerabilities in public clients like mobile apps and single-page applications (SPAs) that cannot safely store a client secret. Why PKCE Is Needed Traditional Authorization Code Flow relies on a client_secret to authenticate the client when exchanging an authorization code for a token. In public clients (like browser apps or mobile apps), this secret cannot be safely stored. Without proper safeguards, attackers could intercept the authorization code during redirection and exchange it for tokens. ...
