SAML (Security Assertion Markup Language) and SAML 2.0 (SAML 2.0) are both versions of the same protocol used for exchanging authentication and authorization data between parties, typically an identity provider (IdP) and a service provider (SP) for enabling single sign-on (SSO) and secure identity management. However, SAML 2.0 is an updated and more widely adopted version of the SAML protocol. Here are some key differences between the two:

Version: SAML stands for "Security Assertion Markup Language" and typically refers to the original version, which is SAML 1.1. SAML 2.0 is the newer, improved version.

Complexity and Flexibility: SAML 2.0 is more comprehensive and flexible than SAML 1.1. It introduced new features and capabilities, such as enhanced security options, improved metadata support, better support for attribute-based authentication, and more advanced bindings and profiles for various use cases.

Metadata: SAML 2.0 includes standardized metadata for identity providers (IdPs) and service providers (SPs), making it easier to configure and set up SSO relationships between them. This metadata simplifies the process of exchanging information about endpoints, certificates, and other essential configuration details.

Bindings and Profiles: SAML 2.0 introduces additional bindings (communication methods) and profiles (use cases) for different scenarios, such as Web SSO profiles, Single Logout, and Enhanced Client or Proxy profiles. These additions provide greater flexibility and support for various integration scenarios.

Security Enhancements: SAML 2.0 includes improvements in security, such as better support for digital signatures and encryption, making it more robust and suitable for secure identity management.

Standardization: SAML 2.0 has gained widespread adoption and support across various industries and applications, making it the de facto standard for SSO and identity management. SAML 1.1, on the other hand, is considered outdated and is rarely used in new deployments.

In summary, while both SAML and SAML 2.0 serve the same fundamental purpose of enabling SSO and secure identity management, SAML 2.0 is a more advanced, standardized, and widely accepted version of the protocol. Organizations and service providers typically prefer to implement SAML 2.0 due to its enhanced features, better security, and broader industry support.
