What is Azure App Registrations?

Azure App Registrations is a feature within Azure Active Directory (Azure AD) that allows you to register your applications (web apps, mobile apps, APIs, etc.) with the Microsoft Identity Platform. This registration creates an identity for your application, enabling it to authenticate users and access resources securely. It's commonly used to grant applications permissions to access Azure resources, other Microsoft services (like Microsoft Graph), or custom APIs, leveraging industry-standard protocols like OAuth 2.0 and OpenID Connect for authentication and authorization.
