Azure Active Directory Basic, often referred to as Azure AD Basic, was a subscription plan offered by Microsoft Azure for its cloud-based identity and access management service, Azure Active Directory (Azure AD). It was designed to provide essential identity and access management features for organizations with simple authentication and security requirements.

Here are some key features and characteristics of Azure AD Basic:

1. User Management: Azure AD Basic allowed organizations to create and manage user accounts and groups. It provided basic identity and access management capabilities, including user provisioning and group membership management.

2. Single Sign-On (SSO): Users could sign in to Azure AD-integrated applications using their Azure AD credentials, enabling single sign-on experiences for cloud-based applications.

3. Directory Integration: Azure AD Basic supported directory synchronization with on-premises Active Directory using Azure AD Connect, allowing organizations to manage hybrid identities.

4. Multi-Factor Authentication (MFA): Azure AD Basic included basic support for multi-factor authentication, which added an extra layer of security to user sign-ins by requiring additional verification methods.

5. Security Defaults: Security defaults provided a set of predefined security configurations and policies to enhance the security of Azure AD Basic environments.

6. Self-Service Password Reset: Users could reset their passwords without IT assistance, reducing the burden on helpdesk resources.

7. Access Panel: Azure AD Basic offered an access panel where users could access and launch their assigned cloud-based applications.

8. Application Proxy: Azure AD Application Proxy allowed on-premises web applications to be securely published for remote access, providing secure remote access to internal applications.
