Step 1: Create a Microsoft Azure Account 📝

Before you can register an application, you need to have a Microsoft Azure account. If you don't have one, you can create it at the Azure portal.

Step 2: Register a New Application 🆕

Navigate to the Azure Active Directory section in the Azure portal. Here, select App registrations and then click on New registration.

Step 3: Configure Your Application ⚙️

You'll need to provide some details about your application:

• Name: This is the name users will see.
• Supported account types: Choose who can use the application.
• Redirect URI (optional): The URL where users will be sent after they authenticate with Microsoft.

After filling in these details, click on the Register button.

Step 4: Get Your Application (Client) ID and Directory (Tenant) ID 🔑

After your application is registered, Azure will provide you with a Client ID and Directory (Tenant) ID. Make sure to note these down as they will be used in your application's code.

Step 5: Generate a New Client Secret 🗝️

In the same application overview page, navigate to Certificates & secrets. Click on New client secret, add a description, select an expiry period, and then click on Add. After it's created, make sure to copy the value of the client secret as it's not retrievable later.

Step 6: Set API Permissions 🛂

Navigate to API permissions and click on Add a permission. Select the APIs and the specific permissions your app requires.
