# SC-300 Lab Tips:

**Tenant Name vs Tenant’s unique name:**

1. **Tenant Name (a.k.a. Directory Name)**
    
    * This is the **display name** you assign to your Azure/Entra tenant.
        
    * You can set or change this to something human-readable like "Marketing" or "MyCompany Directory".
        
    * It’s shown in places like the Azure portal and Microsoft Entra admin center.
        
    * e.g. **Tenant Name**: Bluewave Innovations
        
    
2. **Tenant’s Unique Name (bluewave123)**
    
    * This is the **automatically generated subdomain prefix** used for your default .[onmicrosoft.com](http://onmicrosoft.com) domain.
        
    * It’s globally unique and tied to your tenant forever.
        
    * It’s often used behind the scenes (e.g., when no custom domain is set, during app registrations, etc.)
        
    * You **can’t change** this once the tenant is created.
        
    
    In your case: [bluewave123.onmicrosoft.com](http://bluewave123.onmicrosoft.com)

<div data-node-type="callout-text">You <em>can</em> use <a target="_self" rel="noopener noreferrer nofollow" href="http://yourdomain.com" style="pointer-events: none">yourdomain.com</a> as the tenant name — it’s allowed — but for a cleaner and more polished look, using just the organization name is more common.</div>
