Federation is the practice of linking a user's electronic identity and attributes, stored across multiple distinct identity management systems. Implementing a federated identity management system would be ideal in this situation as it enables the company's employees to use their existing corporate credentials to access the third-party service provider's resources securely. This negates the need for multiple credentials and simplifies the authentication process for users, which directly aligns with the scenario's requirements of minimizing complexity and offering a streamlined process.

Creating additional user credentials for each employee within the partner's system and relying on a central access policy that governs the usage of applications across both entities, are less efficient solutions that increase complexity and management overhead, which does not fulfill the specified criteria of streamlined access. The web authentication standard accentuates a specific method of authentication that can be utilized in federated environments but does not represent the overarching federated identity management system needed here.
