Azure Developer CLI Authentication

Name: tessl/maven-com-azure--azure-identity
Author: tessl

Authenticates using Azure Developer CLI (azd) cached credentials from development environments, ideal for local development scenarios.

Capabilities

Azure Developer CLI Credential

Authenticates using cached credentials from Azure Developer CLI.

/**
 * Azure Developer CLI credential for development environments
 */
class AzureDeveloperCliCredential implements TokenCredential {
    Mono<AccessToken> getToken(TokenRequestContext request);
    AccessToken getTokenSync(TokenRequestContext request);
}

class AzureDeveloperCliCredentialBuilder extends CredentialBuilderBase<AzureDeveloperCliCredentialBuilder> {
    AzureDeveloperCliCredentialBuilder tenantId(String tenantId);
    AzureDeveloperCliCredentialBuilder processTimeout(Duration processTimeout);
    AzureDeveloperCliCredentialBuilder additionallyAllowedTenants(String... additionallyAllowedTenants);
    AzureDeveloperCliCredentialBuilder additionallyAllowedTenants(List<String> additionallyAllowedTenants);
    AzureDeveloperCliCredential build();
}

Usage Examples:

import com.azure.identity.AzureDeveloperCliCredential;
import com.azure.identity.AzureDeveloperCliCredentialBuilder;
import java.time.Duration;

// Basic usage - uses default settings
TokenCredential credential = new AzureDeveloperCliCredentialBuilder()
    .build();

// With specific tenant
TokenCredential tenantCredential = new AzureDeveloperCliCredentialBuilder()
    .tenantId("your-tenant-id")
    .build();

// With custom process timeout
TokenCredential timeoutCredential = new AzureDeveloperCliCredentialBuilder()
    .processTimeout(Duration.ofSeconds(30))
    .build();

// Use with Azure SDK clients
ResourceManagementClient client = ResourceManagementClient.builder()
    .credential(credential)
    .subscriptionId("your-subscription-id")
    .buildClient();

Prerequisites

Azure Developer CLI Installation:

Install Azure Developer CLI: https://docs.microsoft.com/azure/developer/azure-developer-cli/install-azd
Sign in using: azd auth login
Verify authentication: azd auth login --check-status

Supported Authentication Methods:

Interactive browser login
Device code authentication
Service principal (when configured in azd)

Configuration Options

// Multi-tenant support
TokenCredential credential = new AzureDeveloperCliCredentialBuilder()
    .tenantId("primary-tenant-id")
    .additionallyAllowedTenants("tenant1", "tenant2", "tenant3")
    .processTimeout(Duration.ofSeconds(45))
    .build();

Process Timeout

The processTimeout setting controls how long to wait for the azd command to complete:

// Short timeout for fast environments
TokenCredential fastCredential = new AzureDeveloperCliCredentialBuilder()
    .processTimeout(Duration.ofSeconds(10))
    .build();

// Longer timeout for slower environments
TokenCredential slowCredential = new AzureDeveloperCliCredentialBuilder()
    .processTimeout(Duration.ofMinutes(2))
    .build();

Development Workflow

Install and authenticate Azure Developer CLI:

# Install azd
# Sign in interactively
azd auth login

# Or sign in with device code
azd auth login --use-device-code

Use in your Java application:

TokenCredential credential = new AzureDeveloperCliCredentialBuilder().build();

// Use with any Azure SDK client
KeyVaultSecret secret = new SecretClientBuilder()
    .vaultUrl("https://myvault.vault.azure.net/")
    .credential(credential)
    .buildClient()
    .getSecret("mysecret");

Exception Handling

Throws CredentialUnavailableException when:

Azure Developer CLI is not installed
User is not signed in (azd auth login not run)
Process timeout is exceeded
Command execution fails

Troubleshooting

Common Issues:

"azd not found": Ensure Azure Developer CLI is installed and in PATH
"Not signed in": Run azd auth login to authenticate
Timeout errors: Increase processTimeout duration
Permission errors: Ensure azd has necessary permissions for token cache access
