What is the term for the entity that manages Single Sign-On access in DocuSign?

The correct answer is identity provider, which refers to the system or service that authenticates users and provides their identity information to other systems, such as DocuSign, during the login process. This entity is crucial for managing Single Sign-On (SSO) access as it enables users to log in once and gain access to multiple applications without needing to authenticate separately for each one.

In the context of DocuSign, the identity provider communicates the user's credentials and identity assertions to the application, thereby streamlining the authentication process. This capability is particularly beneficial in organizations looking to enhance security while improving user experience by reducing the number of passwords that employees must remember.

The other options, while related to access management or authentication, do not specifically denote the function of managing SSO access in the way that an identity provider does. For example, access manager typically refers to systems or features that govern user permissions after authentication, but it doesn't handle the authentication process itself. Similarly, a single sign-on controller is not a standard term used in the industry, and an authorization server focuses more on issuing tokens to access protected resources rather than managing user identities for SSO directly.
