# Azure Identity library for Rust

Microsoft Entra ID authentication for Azure SDK clients.

Use this skill when:

- An app needs to authenticate to Azure services from Rust
- You need `DeveloperToolsCredential` for local development
- You need `ManagedIdentityCredential` for Azure-hosted workloads
- You need service principal auth with secret or certificate

> **IMPORTANT:** Only use official `azure_*` crates published by the [azure-sdk](https://crates.io/users/azure-sdk) crates.io user. Do NOT use the deprecated `azure_sdk_*` crates (MindFlavor/AzureSDKForRust) or community crates. Official crates use underscores in names and none have version 0.21.0.

> **Note:** The Rust SDK does not have `DefaultAzureCredential`. Use `DeveloperToolsCredential` for local development and `ManagedIdentityCredential` for production.

```rust
// Incorrect in Rust: this type does not exist in azure_identity
use azure_identity::DefaultAzureCredential;
```

## Installation

```sh
cargo add azure_identity azure_core tokio
```

> If your code uses `azure_core` types directly, add `azure_core` to `Cargo.toml`. If you only use service-crate re-exports, direct `azure_core` dependency is optional.
