With SAML, you can enable a single sign-on experience for your users across many SAML-enabled applications
Security Assertion Markup Language 2.0 (SAML) is an open federation standard that allows an identity provider (IdP) to authenticate users and pass identity and security information about them to a service provider (SP), typically an application or service. With SAML, you can enable a single sign-on experience for your users across many SAML-enabled applications and services. Users authenticate with the IdP once using a single set of credentials, and then get access to multiple applications and services without additional sign-ins. Because SAML-enabled applications delegate authentication to an IdP, the SP can automatically grant, revoke, or change the scope of a user’s access to applications and services when an administrator adds, removes, or modifies the user’s information in the IdP.
AWS provides distinct SAML solutions for authenticating your employees, contractors, and partners (workforce) to AWS accounts and business applications, and for adding SAML support to your customer-facing web and mobile applications. To learn more, visit Identity federation in AWS.
