What is a prerequisite for authenticating users with the identity provider in DocuSign?

Claiming a domain is crucial for authenticating users with the identity provider in DocuSign because it verifies that your organization owns the domain being used for authentication purposes. This process ensures that only users with email addresses under the claimed domain can access and authenticate through the identity provider, enhancing both security and control over the user authentication process.

When a domain is claimed, it allows the organization to set up Single Sign-On (SSO) capabilities, integrating with identity providers to facilitate seamless authentication for users. This helps in managing user access and enhances the overall security posture of the organization by making sure that only legitimate users from the claimed domain can log in to their DocuSign accounts.

In contrast, while creating user accounts manually, setting up secure links, or installing additional software serve different administrative or operational functions, they are not direct prerequisites for establishing an authentication pathway through an identity provider. Claiming the domain stands out as the foundational step necessary for configuring user authentication effectively.
