What is Microsoft’s Entra ID?

Microsoft Entra ID (previously known as Azure Active Directory or Azure AD) is Microsoft’s cloud-based identity and access management (IAM) service. 

It provides a centralized platform to authenticate (verify) user identities, authorize access, and manage permissions across both Microsoft services and third-party applications  .

Core Details

1. Identity & Access Management in the Cloud

• Enables organizations to manage user and group accounts in the cloud, with synchronization from on-premises Active Directory using Microsoft Entra Connect  .
  
• Supports diverse authentication methods: passwords, multi-factor authentication (MFA), passwordless options, smart cards, and certificate-based sign-ins  .

2. Single Sign-On (SSO)

• Users can sign in once to seamlessly access Microsoft 365, Azure, Dynamics, and thousands of SaaS apps without re-entering credentials  .

3. Advanced Security & Conditional Access

• Offers Conditional Access policies based on user, location, device health, and risk signals  .
  
• Features identity protection to detect anomalous activity and enforce MFA or block access when threats are detected  .
  
• Privileged Identity Management (PIM) enables just-in-time admin access to reduce risk exposure (available in Premium P2 tier)  .

4. Licensing Tiers & Features

• Free: Basic user/group management, self-service password reset, directory sync, and SSO to apps  .
  
• P1 (Premium 1): Adds features such as conditional access, dynamic groups, group management, and hybrid identity management  .
  
• P2 (Premium 2): Unlocks complete identity protection and PIM ().

Recent Rebranding

• On July 15, 2023, Azure AD was officially renamed to Microsoft Entra ID as part of Microsoft’s Entra product suite  .
