Authentication — Rust SDK Quick Reference

Condensed from azure-identity-rust. Full patterns (ClientSecret, ClientCertificate, WorkloadIdentity, AzurePipelines credentials) in the azure-identity-rust plugin skill if installed.

Install

cargo add azure_identity

Quick Start

use azure_identity::DeveloperToolsCredential;
let credential = DeveloperToolsCredential::new(None)?;

Best Practices

• Use DeveloperToolsCredential for local dev — automatically picks up Azure CLI
• Use ManagedIdentityCredential in production — no secrets to manage
• Clone credentials — credentials are Arc-wrapped and cheap to clone
• Reuse credential instances — same credential can be used with multiple clients
• Use tokio feature — cargo add azure_identity --features tokio
