About Azure AD
[Microsoft Azure AD](https://azure.microsoft.com/en-au/products/active-directory/) is a widely used enterprise identity service that helps secure your data and gives you access control over your tools. You can use cloud-based single sign-on and multifactor authentication through Astro’s seamless integration with Azure AD.
Use Case
Using a third-party [identity provider](/docs/astro/configure-idp) to manage user accounts allows organizations to scale while centralizing access to external tools. Easily manage and monitor Astro application access, [user permissions](/docs/astro/user-permissions), and [security](/docs/astro/security) policies from Azure AD.
