It’s a powerful protocol for securing Angular applications by delegating authentication and authorization to a trusted identity provider like Google, Facebook, or your own backend server.

A well-organized folder structure is essential for developing scalable, maintainable, and efficient Angular applications. It helps teams navigate the codebase easily, promotes reusability, and streamlines the development process.
