Azure Identity is a set of services and libraries that work together to secure and manage identities in Azure. 

Here are some key components:

Azure Active Directory (Azure AD): Azure AD is Microsoft's cloud-based identity and access management service, which helps your employees sign in and access resources. This includes access to internal resources, such as apps on your corporate network and intranet, along with any cloud apps developed by your own organization, or SaaS applications such as Microsoft 365, the Azure portal, and thousands of other SaaS applications.

Azure AD B2C (Business to Consumer): A customer identity access management solution for your consumer-facing web and mobile applications. It scales to hundreds of millions of identities and provides user-friendly sign-up, sign-in, and profile management experiences.

Azure AD B2B (Business to Business): Simplifies the secure sharing of your apps and services with your business partners and customers. It allows users from partner organizations to use their own credentials to authenticate and access your company's resources.

Managed Identities for Azure resources: Provides Azure services with an automatically managed identity in Azure AD. You can use the identity to authenticate to any service that supports Azure AD authentication, including Key Vault, without any credentials in your code.

Azure AD Conditional Access: Provides capabilities to enforce controls on the access to apps in your environment based on specific conditions from a central location.

Azure AD Privileged Identity Management (PIM): Provides oversight of role assignments, self-service, and just-in-time role activation to mitigate the risks of excessive, unnecessary, or misused access permissions on resources.
