| 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 |
The DefaultAzureCredential tries multiple authentication methods in order:
import com.azure.identity.DefaultAzureCredential;
import com.azure.identity.DefaultAzureCredentialBuilder;
().build();
()
.endpoint()
.credential(credential)
.buildClient();
()
.vaultUrl()
.credential(credential)
.buildClient();
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();
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();
import com.azure.identity.ClientSecretCredential;
import com.azure.identity.ClientSecretCredentialBuilder;
ClientSecretCredential credential = new ClientSecretCredentialBuilder()
.tenantId("<tenant-id>")
.clientId("<client-id>")
.clientSecret("<client-secret>")
.build();
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();
Reads credentials from environment variables.
import com.azure.identity.EnvironmentCredential;
import com.azure.identity.EnvironmentCredentialBuilder;
EnvironmentCredential credential = new EnvironmentCredentialBuilder().build();
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/to/cert.pem
AZURE_CLIENT_CERTIFICATE_PASSWORD=<optional-password>
For username/password:
AZURE_TENANT_ID=<tenant-id>
AZURE_CLIENT_ID=<client-id>
AZURE_USERNAME=<username>
AZURE_PASSWORD=<password>
For local development using az login.
import com.azure.identity.AzureCliCredential;
import com.azure.identity.AzureCliCredentialBuilder;
AzureCliCredential credential = new AzureCliCredentialBuilder()
.tenantId("<tenant-id>") // Optional: specific tenant
.build();
For desktop applications requiring user login.
import com.azure.identity.InteractiveBrowserCredential;
import com.azure.identity.InteractiveBrowserCredentialBuilder;
InteractiveBrowserCredential credential = new InteractiveBrowserCredentialBuilder()
.clientId("<client-id>")
.redirectUrl("http://localhost:8080") // Must match app registration
.build();
For headless devices (IoT, CLI tools).
import com.azure.identity.DeviceCodeCredential;
import com.azure.identity.DeviceCodeCredentialBuilder;
DeviceCodeCredential credential = new DeviceCodeCredentialBuilder()
.clientId("<client-id>")
.challengeConsumer(challenge -> {
// Display to user
System.out.println(challenge.getMessage());
})
.build();
Create custom authentication chains.
import com.azure.identity.ChainedTokenCredential;
import com.azure.identity.ChainedTokenCredentialBuilder;
ChainedTokenCredential credential = new ChainedTokenCredentialBuilder()
.addFirst(new ManagedIdentityCredentialBuilder().build())
.addLast(new AzureCliCredentialBuilder().build())
.build();
For Azure Kubernetes Service with workload identity.
import com.azure.identity.WorkloadIdentityCredential;
import com.azure.identity.WorkloadIdentityCredentialBuilder;
// Reads from AZURE_TENANT_ID, AZURE_CLIENT_ID, AZURE_FEDERATED_TOKEN_FILE
WorkloadIdentityCredential credential = new WorkloadIdentityCredentialBuilder().build();
// Or explicit configuration
WorkloadIdentityCredential credential = new WorkloadIdentityCredentialBuilder()
.tenantId("<tenant-id>")
.clientId("<client-id>")
.tokenFilePath("/var/run/secrets/azure/tokens/azure-identity-token")
.build();
Enable persistent token caching for better performance.
// Enable token caching (in-memory by default)
DefaultAzureCredential credential = new DefaultAzureCredentialBuilder()
.enableAccountIdentifierLogging()
.build();
// With shared token cache (for multi-credential scenarios)
SharedTokenCacheCredential credential = new SharedTokenCacheCredentialBuilder()
.clientId("<client-id>")
.build();
import com.azure.identity.AzureAuthorityHosts;
// Azure Government
DefaultAzureCredential govCredential = new DefaultAzureCredentialBuilder()
.authorityHost(AzureAuthorityHosts.AZURE_GOVERNMENT)
.build();
// Azure China
DefaultAzureCredential chinaCredential = new DefaultAzureCredentialBuilder()
.authorityHost(AzureAuthorityHosts.AZURE_CHINA)
.build();
import com.azure.identity.CredentialUnavailableException;
import com.azure.core.exception.ClientAuthenticationException;
try {
DefaultAzureCredential credential = new DefaultAzureCredentialBuilder().build();
AccessToken token = credential.getToken(new TokenRequestContext()
.addScopes("https://management.azure.com/.default"));
} catch (CredentialUnavailableException e) {
// No credential could authenticate
System.out.println("Authentication failed: " + e.getMessage());
} catch (ClientAuthenticationException e) {
// Authentication error (wrong credentials, expired, etc.)
System.out.println("Auth error: " + e.getMessage());
}
Enable authentication logging for debugging.
// Via environment variable
// AZURE_LOG_LEVEL=verbose
// Or programmatically
DefaultAzureCredential credential = new DefaultAzureCredentialBuilder()
.enableAccountIdentifierLogging() // Log account info
.build();
# DefaultAzureCredential configuration
AZURE_TENANT_ID=<tenant-id>
AZURE_CLIENT_ID=<client-id>
AZURE_CLIENT_SECRET=<client-secret>
# Managed Identity
AZURE_CLIENT_ID=<user-assigned-mi-client-id>
# Workload Identity (AKS)
