Azure Identity (Java)

Authenticate Java applications with Azure services using Microsoft Entra ID (Azure AD).

Installation

<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-identity</artifactId>
    <version>1.15.0</version>
</dependency>

Key Concepts

| Credential | Use Case | |------------|----------| | DefaultAzureCredential | Recommended - Works in dev and production | | ManagedIdentityCredential | Azure-hosted apps (App Service, Functions, VMs) | | EnvironmentCredential | CI/CD pipelines with env vars | | ClientSecretCredential | Service principals with secret | | ClientCertificateCredential | Service principals with certificate | | AzureCliCredential | Local dev using az login | | InteractiveBrowserCredential | Interactive login flow | | DeviceCodeCredential | Headless device authentication |

DefaultAzureCredential (Recommended)

The DefaultAzureCredential tries multiple authentication methods in order:

1. Environment variables
2. Workload Identity
3. Managed Identity
4. Azure CLI
5. Azure PowerShell
6. Azure Developer CLI

import com.azure.identity.DefaultAzureCredential;
import com.azure.identity.DefaultAzureCredentialBuilder;

// Simple usage
DefaultAzureCredential credential = new DefaultAzureCredentialBuilder().build();

// Use with any Azure client
BlobServiceClient blobClient = new BlobServiceClientBuilder()
    .endpoint("https://<storage-account>.blob.core.windows.net")
    .credential(credential)
    .buildClient();

KeyClient keyClient = new KeyClientBuilder()
    .vaultUrl("https://<vault-name>.vault.azure.net")
    .credential(credential)
    .buildClient();

Configure DefaultAzureCredential

DefaultAzureCredential credential = new DefaultAzureCredentialBuilder()
    .managedIdentityClientId("<user-assigned-identity-client-id>")  // For user-assigned MI
    .tenantId("<tenant-id>")                                        // Limit to specific tenant
    .excludeEnvironmentCredential()                                 // Skip env vars
    .excludeAzureCliCredential()                                    // Skip Azure CLI
    .build();

Managed Identity

For Azure-hosted applications (App Service, Functions, AKS, VMs).

import com.azure.identity.ManagedIdentityCredential;
import com.azure.identity.ManagedIdentityCredentialBuilder;

// System-assigned managed identity
ManagedIdentityCredential credential = new ManagedIdentityCredentialBuilder()
    .build();

// User-assigned managed identity (by client ID)
ManagedIdentityCredential credential = new ManagedIdentityCredentialBuilder()
    .clientId("<user-assigned-client-id>")
    .build();

// User-assigned managed identity (by resource ID)
ManagedIdentityCredential credential = new ManagedIdentityCredentialBuilder()
    .resourceId("/subscriptions/<sub>/resourceGroups/<rg>/providers/Microsoft.ManagedIdentity/userAssignedIdentities/<name>")
    .build();

Service Principal with Secret

import com.azure.identity.ClientSecretCredential;
import com.azure.identity.ClientSecretCredentialBuilder;

ClientSecretCredential credential = new ClientSecretCredentialBuilder()
    .tenantId("<tenant-id>")
    .clientId("<client-id>")
    .clientSecret("<client-secret>")
    .build();

Service Principal with Certificate

import com.azure.identity.ClientCertificateCredential;
import com.azure.identity.ClientCertificateCredentialBuilder;

// From PEM file
ClientCertificateCredential credential = new ClientCertificateCredentialBuilder()
    .tenantId("<tenant-id>")
    .clientId("<client-id>")
    .pemCertificate("<path-to-cert.pem>")
    .build();

// From PFX file with password
ClientCertificateCredential credential = new ClientCertificateCredentialBuilder()
    .tenantId("<tenant-id>")
    .clientId("<client-id>")
    .pfxCertificate("<path-to-cert.pfx>", "<pfx-password>")
    .build();

// Send certificate chain for SNI
ClientCertificateCredential credential = new ClientCertificateCredentialBuilder()
    .tenantId("<tenant-id>")
    .clientId("<client-id>")
    .pemCertificate("<path-to-cert.pem>")
    .sendCertificateChain(true)
    .build();

Environment Credential

Reads credentials from environment variables.

import com.azure.identity.EnvironmentCredential;
import com.azure.identity.EnvironmentCredentialBuilder;

EnvironmentCredential credential = new EnvironmentCredentialBuilder().build();

Required Environment Variables

For service principal with secret:

AZURE_TENANT_ID=<tenant-id>
AZURE_CLIENT_ID=<client-id>
AZURE_CLIENT_SECRET=<client-secret>

For service principal with certificate:

AZURE_TENANT_ID=<tenant-id>
AZURE_CLIENT_ID=<client-id>
AZURE_CLIENT_CERTIFICATE_PATH=/path/
