Microsoft Entra ID (formerly known as Microsoft Azure Active Directory or Azure AD) is a cloud-based identity and access management (IAM) solution.

[1] Entra ID provides users with single sign-on experience, called "work or school accounts",[2] regardless of whether their applications are cloud-based or on-premises.

Entra ID offers various authentication methods, including password-based, multi-factor, smart card, and certificate-based authentication.

It also includes several security features, such as conditional access policies, risk-based authentication, and identity protection.
