OAuth and API Authentication: Accessing Secure APIs # Welcome back to our programming tutorial series! Today, we’ll explore OAuth and other forms of API authentication, which allow you to securely access protected APIs. Many APIs require authentication to ensure that only authorized users can access sensitive data or perform certain actions. What Is OAuth? # OAuth (Open Authorization) is an open standard for access delegation. It allows users to grant third-party applications limited access to their resources without exposing their credentials. ...
