What is a client secret in Azure?

A client secret is a credential used to authenticate a client application to an Azure Active Directory (Azure AD) tenant. It is a shared secret between the client application and Azure AD, and it is used to prove the identity of the client application when it makes requests to Azure AD.

Client secrets are typically generated by Azure AD when a new client application is registered. They can also be rotated manually by the application administrator. Client secrets should be kept confidential, as they can be used to impersonate the client application and access its resources.

Client secrets are an important part of the OAuth 2.0 authorization framework, which is used to delegate access to protected resources. When a client application makes a request to an Azure AD-protected resource, it must present a valid client secret in order to be authorized.

There are a number of different ways to use client secrets in Azure AD. For example, they can be used to authenticate:

Web applications
Mobile applications
Desktop applications
Service-to-service applications

Client secrets are a powerful tool for securing access to Azure AD resources. However, it is important to use them carefully and to keep them confidential.
