App registrations allow applications to authenticate users and access Azure resources securely. ### Key Concepts | Concept | Description | |---------|-------------| | **App Registration** | Configuration that allows an app to use Microsoft identity platform | | **Application (Client) ID** | Unique identifier for your application | | **Tenant ID** | Unique identifier for your Azure AD tenant/directory | | **Client Secret** | Password for the application (confidential clients only) | | **Redirect URI** | URL where authentication responses are sent | | **API Permissions** | Access scopes your app requests | | **Service Principal** | Identity created in your tenant when you register an app | ### Application Types | Type | Use Case | |------|----------| | **Web Application** | Server-side apps, APIs | | **Single Page App (SPA)** | JavaScript/React/Angular apps | | **Mobile/Native App** | Desktop, mobile apps | | **Daemon/Service** | Background services, APIs | ## Core Workflow ### Step 1: Register the Application Create an app registration in the Azure portal or using Azure CLI. **Portal Method:** 1. Navigate to Azure Portal → Microsoft Entra ID → App registrations 2. Click "New registration" 3. Provide name, supported account types, and redirect URI 4. Click "Register" **CLI Method:** See [references/cli-commands.md](references/cli-commands.md) **IaC Method:** See [references/BICEP-EXAMPLE.bicep](references/BICEP-EXAMPLE.bicep) It's highly recommended to use the IaC to manage Entra app registration if you already use IaC in your project, need a scalable solution for managing lots of app registrations or need fine-grained audit history of the configuration changes. ### Step 2: Configure Authentication Set up authentication settings based on your application type. - **Web Apps**: Add redirect URIs, enable ID tokens if needed - **SPAs**: Add redirect URIs, enable implicit grant flow if necessary - **Mobile/Desktop**: Use `http://localhost` or custom URI scheme - **Services**: No redirect URI needed for client credentials flow ### Step 3: Configure API Permissions Grant your application permission to access Microsoft APIs or your own APIs. **Common Microsoft Graph Permissions:** - `User.Read` - Read user profile - `User.ReadWrite.All` - Read and write all users - `Directory.Read.All` - Read directory data - `Mail.Send` - Send mail as a user **Details:** See [references/api-permissions.md](references/api-permissions.md) ### Step 4: Create Client Credentials (if needed) For confidential client applications (web apps, services), create a client secret, certificate or federated identity credential. **Client Secret:** - Navigate to "Certificates & secrets" - Create new client secret - Copy the value immediately (only shown once) - Store securely (Key Vault recommended) **Certificate:** For production environments, use certificates instead of secrets for enhanced security. Upload certificate via "Certificates & secrets" section. **Federated Identity Credential:** For dynamically authenticating the confidential client to Entra platform. ### Step 5: Implement OAuth Flow Integrate the OAuth flow into your application code. **See:** - [references/oauth-flows.md](references/oauth-flows.md) - OAuth 2.0 flow details - [references/console-app-example.md](references/console-app-example.md) - Console app implementation ## Common Patterns ### Pattern 1: First-Time App Registration Walk user through their first app registration step-by-step. **Required Information:** - Application name - Application type (web, SPA, mobile, service) - Redirect URIs (if applicable) - Required permissions **Script:** See [references/first-app-registration.md](references/first-app-registration.md) ### Pattern 2: Console Application with User Authentication Create a .NET/Python/Node.js console app that authenticates users. **Required Information:** - Programming language (C#, Python, JavaScript, etc.) - Authentication library (MSAL recommended) - Required permissions **Example:** See [references/console-app-example.md](references/console-app-example.md) ### Pattern 3: Service-to-Service Authentication Set up daemon/service authentication without user interaction. **Required Information:** - Service/app name - Target API/resource - Whether to use secret or certificate **Implementation:** Use Client Credentials flow (see [references/oauth-flows.md#client-credentials-flow](references/oauth-flows.md#client-credentials-flow)) ## MCP Tools and CLI ### Azure CLI Commands | Command | Purpose | |---------|---------| | `az ad app create` | Create new app registration | | `az ad app list` | List app registrations | | `az ad app show` | Show app details | | `az ad app permission add` | Add API permission | | `az ad app credential reset` | Generate new client secret | | `az ad sp create` | Create service principal | **Complete reference:** See [references/cli-commands.md](references/cli-commands.md) ### Microsoft Authentication Library (MSAL) MSAL is the recommended library for integrating Microsoft identity platform. **Supported Languages:** - .NET/C# - `Microsoft.Identity.Client` - JavaScript/TypeScript - `@azure/msal-browser`, `@azure/msal-node` - Python - `msal` **Examples:** See [references/console-app-example.md](references/console-app-example.md) ## Security Best Practices | Practice | Recommendation | |----------|---------------| | **Never hardcode secrets** | Use environment variables, Azure Key Vault, or managed identity | | **Rotate secrets regularly** | Set expiration, automate rotation | | **Use certificates over secrets** | More secure for production | | **Least privilege permissions** | Request only required API permissions | | **Enable MFA** | Require multi-factor authentication for users | | **Use managed identity** | For Azure-hosted apps, avoid secrets entirely | | **Validate tokens** | Always validate issuer, audience, expiration | | **Use HTTPS only** | All redirect URIs must use HTTPS (except localhost) | | **Monitor sign-ins** | Use Entra ID sign-in logs for anomaly detection | ## SDK Quick References - **Azure Identity**: [Python](references/sdk/azure-identity-py.md) | [.NET](references/sdk/azure-identity-dotnet.md) | [TypeScript](references/sdk/azure-identity-ts.md) | [Java](references/sdk/azure-identity-java.md) | [Rust](references/sdk/azure-identity-rust.md) - **Key Vault (secrets)**: [Python](references/sdk/azure-keyvault-py.md) | [TypeScript](references/sdk/azure-keyvault-secrets-ts.md) - **Auth Events**: [.NET](references/sdk/microsoft-azure-webjobs-extensions-authentication-events-dotnet.md) ## References - [OAuth Flows](references/oauth-flows.md) - Detailed OAuth 2.0 flow explanations - [CLI Commands](references/cli-commands.md) - Azure CLI reference for app registrations - [Console App Example](references/console-app-example.md) - Complete working examples - [First App Registration](references/first-app-registration.md) - Step-by-step guide for beginners - [API Permissions](references/api-permissions.md) - Understanding and configuring permissions - [Troubleshooting](references/troubleshooting.md) - Common issues and solutions ## External Resources - [Microsoft Identity Platform Documentation](https://learn.microsoft.com/entra/identity-platform/) - [OAuth 2.0 and OpenID Connect protocols](https://learn.microsoft.com/entra/identity-platform/v2-protocols) - [MSAL Documentation](https://learn.microsoft.com/entra/msal/) - [Microsoft Graph API](https://learn.microsoft.com/graph/) --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/jongio) — claim your Tome and manage your conversions.
