Step 1 — App Registration

CloudSync uses an Azure App Registration to authenticate your users via Microsoft Entra ID (Azure AD). You only need to do this once.

1.1 Create the registration

1. Navigate to the Azure Portal
2. Go to Microsoft Entra ID → App registrations → New registration
3. Fill in the form:

   • Name: CloudSync (or any name you prefer)
   • Supported account types: Accounts in this organizational directory only
   • Redirect URI: Leave blank for now — you'll add this after deployment
4. Click Register

Copy the Application (client) ID shown on the overview page — you'll need it during first login.

1.2 Configure API permissions

Go to API permissions → Add a permission → Microsoft Graph → Delegated permissions and add the following:

Permission	Type	Description
email	Delegated	View users' email address
openid	Delegated	Sign users in
profile	Delegated	View users' basic profile
User.Read	Delegated	Sign in and read user profile

Once added, click Grant admin consent for [your organization] and confirm.

All four permissions should show a green Granted status before proceeding.

1.3 Create a client secret

1. Go to Certificates & secrets → New client secret
2. Set a description (e.g. cloudsync-vm) and an expiry
3. Click Add
4. Copy the secret value immediately — it won't be shown again

Store the client secret securely. You will be prompted to enter it on first SSH login to your VM.
