Microsoft Azure Active Directory (Azure AD) is a cloud-based identity and access management service that enables organizations to manage users and access to their applications and resources. It provides user management, authentication, authorization, access management, and security capabilities.
It supports popular authentication protocols, such as SAML, OAuth, and OpenID Connect. It also enables synchronization of users and groups with local directories such as Active Directory.
Azure AD also offers the ability to manage identities and access for third-party SaaS applications, such as Salesforce, Workday, and Box, using enterprise application functionality. This is also the case for mobile applications.
