Azure Active Directory and Entra ID for IT Administrators
Microsoft rebranded Azure Active Directory as Microsoft Entra ID in 2023. If you work in IT administration and manage users, devices, or access permissions in a Microsoft environment, this is not a product you get to ignore. Whether you call it Azure AD or Entra ID, the platform controls who can access what across Microsoft 365, Azure, and every application your organization connects to it.
This article explains what Entra ID does, why it matters for IT administrators, and what training and certifications support this work.
What Is Microsoft Entra ID
Microsoft Entra ID is a cloud-based identity and access management platform. It handles authentication and authorization for users across Microsoft cloud services and any third-party applications integrated with it.
In practical terms, Entra ID is the system that verifies a user is who they claim to be before granting access, controls which resources each user account is allowed to reach, manages devices registered to your organization, enforces conditional access policies based on user, location, device, and risk signals, and connects single sign-on across SaaS applications.
If your organization runs Microsoft 365 — Exchange, Teams, SharePoint, OneDrive — Entra ID is already in play. Every user account, every group, every access policy flows through it.
The name change from Azure Active Directory to Microsoft Entra ID reflects Microsoft’s broader Entra product family, which includes external identity, permissions management, and verified ID tools. The underlying technology is the same. The licensing tiers and feature set have not changed in a way that disrupts existing deployments.
How Entra ID Differs From On-Premises Active Directory
IT administrators who come from a traditional Windows Server background know Active Directory (AD) as the on-premises directory service. Entra ID is not the same product running in the cloud. They serve related purposes but operate differently.
On-premises Active Directory uses Kerberos and NTLM for authentication. It manages computers joined to a domain and applies Group Policy objects to control configuration. If you have ever set up a domain controller, created organizational units, or linked a GPO, you have worked with on-premises AD.
Entra ID uses OAuth 2.0, OpenID Connect, and SAML for authentication. It manages cloud-native and cloud-registered devices. Instead of Group Policy, it uses Intune and conditional access policies to control device configuration and access decisions.
Many organizations run both. Microsoft Entra Connect is the tool that synchronizes on-premises Active Directory with Entra ID, allowing a hybrid identity setup where users have a single account that works both locally and in the cloud. Managing this synchronization correctly is one of the more technically demanding parts of hybrid identity administration.
If your organization is moving workloads to Azure or expanding its Microsoft 365 deployment, you will encounter this hybrid setup regularly. Understanding where on-premises AD ends and Entra ID begins — and how they stay in sync — is core knowledge for IT administrators in 2026.
Core Administrative Tasks in Entra ID
The day-to-day work of an Entra ID administrator covers several areas.
User and group management covers creating and managing user accounts, assigning licenses, managing group membership, and controlling administrative roles. Entra ID uses role-based access control, which means administrators assign users to specific roles — like User Administrator or Helpdesk Administrator — rather than giving full global admin access to everyone who needs some administrative permissions.
Conditional access is one of the most important areas of Entra ID administration. Conditional access policies define rules that must be met before a user is granted access. Rules combine conditions — who the user is, what device they are using, what application they are accessing, where they are signing in from — with enforcement decisions like requiring multi-factor authentication or blocking access outright. Designing conditional access policies that protect the organization without creating friction for legitimate users requires judgment and testing.
Multi-factor authentication configuration falls under Entra ID. Administrators manage which authentication methods are available, which are required, and how registration is handled for new users and existing staff. Passwordless authentication using Microsoft Authenticator or FIDO2 security keys is increasingly common, and Entra ID supports it natively.
Application registration and enterprise applications covers connecting SaaS tools to Entra ID for single sign-on. When an organization adds a new SaaS application — a CRM, an HR platform, a project management tool — Entra ID serves as the identity provider so users log in with their organizational account rather than a separate credential. Setting up and maintaining these integrations is a regular part of the work.
Device management covers devices registered or joined to Entra ID, including Azure AD Joined, Hybrid Azure AD Joined, and registered devices. This connects directly to Intune and endpoint management, where device compliance affects whether conditional access allows login.
Why This Matters for Early IT Administrators
If you are in the first few years of an IT administration career, Entra ID is one of the most important platforms to develop depth in. The reasons are practical.
Almost every organization using Microsoft 365 is an Entra ID customer. The platform is present in Canadian workplaces across sectors — finance, healthcare, government, education, and private enterprise. Knowing how to manage identities and access in Entra ID is a direct requirement for IT support, systems administration, and cloud administration roles.
Security is increasingly tied to identity. Most data breaches involve compromised credentials. Organizations respond by strengthening identity controls — conditional access, MFA, privileged identity management. IT administrators who understand how to configure and troubleshoot these controls contribute directly to security outcomes, not just routine maintenance.
Career progression in Microsoft cloud administration leads through Entra ID. The Microsoft AZ-104 Azure Administrator certification and the MS-102 Microsoft 365 Administrator certification both include Entra ID content. If you are working toward either of those credentials, you need to be comfortable with identity and access management concepts and tasks.
You can explore the full range of Microsoft training and certification programs at Ultimate IT Courses to see which paths include Entra ID content.
Relevant Microsoft Certifications
Several certifications test Entra ID knowledge at different levels.
AZ-104 Microsoft Azure Administrator includes a significant identity and governance section covering Entra ID user and group management, role-based access control, and Azure policies. This is the most direct certification for IT administrators managing Azure environments and is the recommended path if your focus is Azure infrastructure. See the full AZ-104 skills outline on Microsoft Learn for the identity content coverage.
MS-102 Microsoft 365 Administrator focuses on the Microsoft 365 environment and includes Entra ID identity management, conditional access, authentication methods, and app management. This is the right certification if your primary environment is Microsoft 365 rather than Azure IaaS.
SC-300 Microsoft Identity and Access Administrator is the dedicated identity certification. It covers Entra ID in depth — identity governance, entitlement management, privileged identity management, and identity protection. If identity and access management is your specialty or the direction you want to develop in, SC-300 gives you the most comprehensive credential. Review the SC-300 certification details on Microsoft Learn to understand what it covers.

What Hands-On Practice Looks Like
Reading about Entra ID is not enough. The platform is managed through the Azure portal, the Entra admin center, and PowerShell. You need time in the interface to build the practical understanding that makes troubleshooting and configuration decisions intuitive.
Microsoft provides a free developer tenant through the Microsoft 365 Developer Program. This gives you a 90-day sandbox environment with a full Microsoft 365 deployment, Entra ID included, where you create users, configure conditional access, register applications, and test authentication flows without risk to a production environment.
Work through the following in your sandbox: create user accounts and assign roles, build a conditional access policy that requires MFA for a specific application, register a test application and configure single sign-on, and run through the Microsoft Entra Connect setup documentation even if you are not connecting to on-premises AD. Each of these exercises builds practical familiarity that exam preparation alone does not provide.
The Bottom Line
Azure Active Directory — now Microsoft Entra ID — is central to IT administration in organizations using Microsoft cloud services. If you manage users, devices, or access in a Microsoft environment, this platform is part of your daily work whether you have studied it intentionally or not.
For early IT administrators, developing real depth in Entra ID is one of the highest-value skills you can build right now. It supports certification paths including AZ-104 and MS-102, it directly addresses the security priorities organizations are focused on, and it is in demand across virtually every sector of the Canadian job market.
Start with the hands-on sandbox. Then structure your study around a certification that matches where you want to take your career. Explore Microsoft cloud training programs to see what fits your path.
