Amazon Connect customers can now use federated single sign-on (SSO) using SAML 2.0 to access Amazon Connect. This allows contact center agents and managers to access Amazon Connect with their existing corporate credentials. As an administrator, you can enforce password policies, and use your existing SAML 2.0 user directory to control access to Amazon Connect, based on location, the device they are using, or their role.
