In AWS Identity Access Management, which protocol allows for federated users to have SSO access to the AWS console?

The correct answer is Security Assertion Markup Language (SAML) 2.0. This protocol is widely utilized for enabling Single Sign-On (SSO) functionality, particularly in scenarios where federated users need access to the AWS Management Console.

SAML 2.0 facilitates the exchange of authentication and authorization data between an identity provider (IdP) and a service provider (in this case, AWS). By allowing users to authenticate with their corporate IdP and then seamlessly access AWS resources without needing to enter their credentials multiple times, it enhances security while improving user experience.

In the context of AWS, SAML 2.0 enables organizations to implement federated access, allowing users to sign in to the AWS console using their existing corporate credentials. This integration is critical for organizations that want to centralize their identity management and ensure that access control adheres to enterprise policies and compliance standards.

Other protocols mentioned, such as OAuth 2.0 and OpenID Connect, are primarily designed for authorization workflows and are generally used for granting third-party applications access to user data without sharing passwords, rather than for SSO access to web applications like the AWS console. LDAP (Lightweight Directory Access Protocol) is used for directory services but doesn't specifically facilitate S
