Azure App Registration
What is Azure App Registration?
Azure App Registration in Microsoft Azure is essential for managing identity and access for applications, enabling secure interactions with Azure services and APIs. It facilitates Single Sign-On (SSO) and integrates applications with Azure Active Directory (Azure AD), ensuring authentication and resource access.
Applications authenticate with Azure using credentials like client ID, client secret, or certificates obtained through App Registration. They leverage protocols such as OAuth 2.0 or OpenID Connect to securely access Azure resources and APIs.
Client applications, used by end-users, often request permissions to interact with service applications, which provide backend functionality. Defined permissions ensure secure communication—application permissions allow apps to act independently, while delegated permissions enable apps to act on behalf of users.
Monitoring and auditing activities related to App Registration are supported by tools like Azure Monitor and Azure Security Center, ensuring transparency and security in application interactions.
Client ID vs Client Secret
The Client ID is a unique identifier assigned to the application. The Client Secret is a confidential key used during the authentication process. It's known only to the application and the Azure authorization server and is used to verify the application's identity.
Tenant ID
The Tenant ID represents the Azure Active Directory (Azure AD) instance (or tenant) where the application is registered. It provides the authentication and authorization context, ensuring the application interacts with the correct directory and associated resources.
