Entra ID (formerly known as Azure Active Directory) is the central nervous system of identity and access management (IAM) for the Microsoft cloud. In this article, I’ll break down the complexities of Entra ID into a digestible, authoritative tutorial designed to take you from a curious beginner to a confident administrator.
Microsoft Entra ID Tutorial For Beginners
What is Microsoft Entra ID? (The Evolution of Identity)
In late 2023, Microsoft rebranded Azure AD to Microsoft Entra ID. This wasn’t just a name change; it was a signal that identity now spans beyond just “Azure.” It covers every app, every user, and every device in your ecosystem.
Why Enterprises are Moving to Entra ID
- Zero Trust Security: It operates on the “never trust, always verify” principle.
- Single Sign-On (SSO): One set of credentials for thousands of apps.
- Global Scalability: Whether you have five employees in Austin or 50,000 across the globe, the infrastructure scales instantly.
- Seamless Integration: It is the native identity provider for Microsoft 365, Teams, and the Azure Portal.
Understanding the Licensing Landscape
One of the most common questions I get from IT managers is, “Which version do I need?” Microsoft offers several tiers, and picking the right one is crucial for your budget and security posture.
| License Tier | Target Audience | Key Features |
| Entra ID Free | Small startups / Home labs | Basic user management, 50k objects, limited SSO. |
| Microsoft 365 Apps | General business users | Basic security, self-service password reset for cloud users. |
| Entra ID P1 | Mid-market enterprises | Conditional Access, Advanced Group Management. |
| Entra ID P2 | High-security / Enterprises | Identity Protection, Privileged Identity Management (PIM). |
When I start a project for a new client, the first place I take them is the Microsoft Entra Admin Center (formerly the Azure Portal).
1. Accessing the Portal
To follow along, you’ll head to entra.microsoft.com. Log in with your Global Administrator credentials. If you are a beginner, I highly recommend setting up a “Sandbox” or “Developer” tenant so you aren’t experimenting on your live corporate data.
2. The Overview Dashboard
The dashboard is your cockpit. You’ll see:
- Tenant ID: The unique identifier for your organization.
- User Count: How many digital identities you are managing.
- Secure Score: A percentage that tells you how well you’ve followed Microsoft’s security best practices.
Tutorial Part 2: Managing Users and Groups
Identity management starts with the “Who.” In Entra ID, we deal with two primary types of identities: Members and Guests.
Creating a New User
In my workflow, I prefer a standardized approach to user creation to avoid messy directories.
- On the left-hand sidebar, select Identity > Users > All users.
- Click New user > Create new user.
- Identity Details: Enter the User Principal Name (UPN), such as
jsmith@yourfirm.com. Ensure the “Display Name” matches your company’s HR records (e.g., “John Smith”). - Password: I always recommend letting Entra ID generate a strong password and checking the “User must change password on next sign-in” box.
The Power of Groups
Managing individuals is a nightmare. Managing Groups is how you scale.
- Security Groups: Used to grant access to resources (like a SharePoint site).
- Microsoft 365 Groups: Used for collaboration (creates a shared mailbox, calendar, and Team).
- Dynamic Groups (P1/P2 Feature): This is my favorite “pro” tip. You can set a rule like “If Department equals ‘Sales’, add to Sales Group automatically.” This saves hours of manual labor for IT teams in high-growth cities like Nashville or Denver.
Tutorial Part 3: Implementing Security Essentials
If you take only one thing away from this tutorial, let it be this: Passwords are not enough. In 2026, a password-only environment is a liability.
