• A. A type of database management system
• B. An authorization method
• C. A type of hardware
• D. A network topology

Answer: (B)

In the context of identity management, the term 'OAuth' refers to an authorization method that allows a user to grant third-party applications limited access to their resources without sharing their credentials. OAuth enables users to authorize applications to interact with their information on other platforms securely.

This framework uses tokens to grant access, ensuring that the user's credentials are never exposed to the third-party applications. Instead of needing to give out a username and password, users can simply approve the application to access specific information for a designated period.

This method is widely used in scenarios where users need to connect various applications and services, facilitating secure resource sharing while maintaining user control over their data. As a result, it plays a crucial role in enhancing security and user experience in modern identity management systems.
