Understanding Authentication and Authorization in .NET C#
In the world of software development, security is paramount. Two crucial concepts that play a pivotal role in ensuring the security of applications are authentication and authorization. These terms might sound similar, but they serve distinct purposes in safeguarding sensitive information and controlling user access. In this blog, we'll delve into the concepts of authentication and authorization and provide examples of how they are implemented in a .NET C# application. Authentication: Who are you? Authentication is the process of verifying the identity of a user, ensuring that they are who they claim to be. In a digital context, this often involves presenting credentials like usernames and passwords. However, more secure methods like multi-factor authentication (MFA) or biometric verification (fingerprint, facial recognition) have gained popularity in recent years. Example in .NET C#: Suppose we have a web application where users need to log in before accessing their personalized d...
