Which protocols are commonly associated with Salesforce Identity for SSO?

The protocols commonly associated with Salesforce Identity for Single Sign-On (SSO) include SAML, OAuth, and OpenID Connect because these protocols are specifically designed to facilitate secure authentication and authorization across different applications and services.

SAML (Security Assertion Markup Language) is widely used for exchanging authentication and authorization data between an identity provider and a service provider, making it ideal for enabling SSO in web applications. It allows users to authenticate once and gain access to multiple applications without needing to log in each time.

OAuth is a protocol that allows for secure delegated access, enabling users to grant third-party applications limited access to their resources without sharing their passwords. This protocol supports various use cases, including SSO, by allowing users to authenticate using their existing accounts from identity providers.

OpenID Connect builds on top of OAuth, providing an identity layer. It allows clients to verify the identity of the user based on the authentication performed by an authorization server, facilitating SSO by allowing users to log in using credentials from an OpenID provider.

Together, these protocols provide comprehensive support for SSO, enhancing user experience by streamlining authentication processes while maintaining security and user privacy.
