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:

Environment variables
Workload Identity
Managed Identity
Azure CLI
Azure PowerShell
Azure Developer CLI
