What term is used for a protocol that provides end-user authentication using decentralized IDs?

The term for a protocol that provides end-user authentication using decentralized IDs is OpenID. OpenID is an open standard that allows users to be authenticated by a third party, known as an OpenID provider, without needing to create a separate login for each service. This approach enhances security and user convenience by allowing individuals to use a single identity across multiple platforms while maintaining control over their personal information.

Decentralized IDs (DIDs) offer a significant advantage in terms of privacy and security. With DIDs, users can manage their identities without relying on a central authority, which reduces the risk of identity theft and data breaches associated with centralized login systems. OpenID leverages this approach by enabling federated identity management, allowing users to authenticate using their chosen OpenID provider that supports DIDs.

This capability sets OpenID apart from other options listed, such as Secure Sockets Layer (SSL), which focuses on securing connections, Lightweight EAP (LEAP), which is specific to wireless authentication, and Cross-Certification, which deals with trusting different Public Key Infrastructures. Understanding OpenID in this context highlights its role in modern identity solutions driven by the need for greater privacy and control in digital interactions.
