In today's digital landscape, managing identity and access to web applications is increasingly complex, making identity and access management (IAM) protocols like Security Assertion Markup Language (SAML) and Open Authorization (OAuth) crucial. SAML is an open authentication standard that enables users to access multiple web applications with one set of credentials, facilitating single sign-on (SSO) by transferring identity data through XML between an Identity Provider and a Service Provider. Conversely, OAuth is a token-based authorization standard allowing third-party applications to access user resources without sharing user credentials, typically using JSON-based messages. While SAML is more suited for enterprise applications and federated identity, OAuth is better for delegating authorization to third-party applications. These protocols can be combined for enhanced security and user experience by utilizing SAML for SSO and OAuth for resource authorization. However, their implementation can be complex, prompting tools like Descope to offer simplified authentication flows through a drag-and-drop editor, streamlining the process for developers.
