What tool can Jim use to allow cloud-based applications to access data on his behalf?

OAuth is a widely used authorization framework that allows third-party applications to access a user's data without requiring users to share their credentials. It enables secure delegated access, allowing applications to perform actions on behalf of a user while maintaining the security of their account.

When a user utilizes OAuth, they can authorize a cloud-based application to access specific data stored in another service (like a social media account or cloud storage) without giving that application their actual login credentials. The application receives an access token which it can use to interact with the user's data within the permissions granted. This way, OAuth ensures that sensitive information remains secure while still providing the necessary functionality for integrating different services.

In contrast, single sign-on (SSO) provides a method for users to log into multiple applications with a single set of credentials, but it does not specifically address the need for third-party applications to access data on a user's behalf. Encryption tokens, while critical for securing data, do not facilitate authorization or delegated access. Common Access Card (CAC) authentication is used in government and military contexts for identity verification and access control, but again, it does not allow for the type of delegated access that OAuth provides.
