You won't find a direct "Client ID" associated with your personal Microsoft 365 account. However, if you're looking for credentials to access Microsoft 365 APIs or resources programmatically, there are two possibilities:
1. Client ID and Secret for an Azure AD App: If you've created an application registered in Azure Active Directory (Azure AD) to interact with Microsoft 365 services, the Client ID for that application serves as your identification. Here's how to find it:
- Log in to the Azure portal
- Navigate to Azure Active Directory.
- Select App registrations.
- Locate the Azure AD app you want to find the Client ID for.
- Click on the app to open its details.
- Under Essentials, you'll find the Application (client) ID.
2. Tenant ID for Administrative Access: While not technically a "Client ID," the Tenant ID identifies your specific Microsoft 365 organization. This can be used for administrative purposes with certain Microsoft 365 APIs. Here's how to find it:
- Log in to the Azure portal
- Navigate to Azure Active Directory.
- Select Properties.
- Under Directory name, you'll find the Tenant ID.
