Oauth 2.0 Protocol
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
OAuth 2.0 is an open standard authorization framework that enables third-party applications to obtain limited access to user accounts on a web service. It delegates user authentication to the service that hosts the user account, allowing applications to access resources without handling user credentials directly. Widely adopted across many web platforms, OAuth 2.0 enhances security and user experience by providing a flexible and standardized mechanism for secure delegated access.
