## What it does

azure-identity-py covers authentication for Python applications that use Azure SDK clients with Microsoft Entra ID. It explains how to work with `DefaultAzureCredential`, managed identity, service principals backed by a secret or certificate, and direct token retrieval through `get_token()`.

The material also covers `get_bearer_token_provider`, which adapts a credential for clients such as the Azure OpenAI SDK. It includes environment variables such as `AZURE_TENANT_ID`, `AZURE_CLIENT_ID`, `AZURE_CLIENT_SECRET`, `AZURE_CLIENT_CERTIFICATE_PATH`, and `AZURE_TOKEN_CREDENTIALS`. Install the main package with `pip install azure-identity`; VS Code broker authentication uses `azure-identity-broker`.

Python 3.9 or newer is required. Older Python versions will block the `azure-identity` examples.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add microsoft/skills --skill azure-identity-py -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/azure-identity-py/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/azure-identity-py/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/azure-identity-py/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/azure-identity-py/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install microsoft/skills azure-identity-py
```

2. **Manually: put the files in place**
- File: `.github/skills/azure-identity-py/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/microsoft/skills --path .github/plugins/azure-sdk-python/skills/azure-identity-py
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/azure-identity-py/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/microsoft/skills/tree/HEAD/.github/plugins/azure-sdk-python/skills/azure-identity-py/SKILL.md

## When to use it
- authenticate a Python app with Microsoft Entra ID
- configure `DefaultAzureCredential` across local and Azure environments
- use managed identity for an Azure-hosted workload
- pass a bearer token provider to Azure OpenAI
- diagnose failures in a credential chain

## Example prompts
- Configure this Python app with `DefaultAzureCredential` and explain which credentials it tries.
- Connect `AzureOpenAI` with `get_bearer_token_provider` instead of a static API key.
- Investigate why `DefaultAzureCredential` cannot obtain a token and check the environment variables.

# Azure Identity library for Python

Authentication library for Azure SDK clients using Microsoft Entra ID.

Use this skill when:
- An app needs to authenticate to Azure services from Python
- You need `DefaultAzureCredential` for local dev + Azure deployment
- You need `ManagedIdentityCredential` for Azure-hosted workloads
- You need service principal auth with secret or certificate
- You need direct token acquisition with `get_token()`
- You need to troubleshoot credential chain failures

## Installation

```bash
pip install azure-identity
```

For VS Code or broker-based desktop auth:

```bash
pip install azure-identity-broker
```

## Python Version

`azure-identity` supports Python 3.9+.

## Environment Variables

```bash
# Service principal with client secret
AZURE_TENANT_ID=<your-tenant-id>
AZURE_CLIENT_ID=<your-client-id>
AZURE_CLIENT_SECRET=<your-client-secret>

# Service principal with certificate
AZURE_TENANT_ID=<your-tenant-id>
AZURE_CLIENT_ID=<your-client-id>
AZURE_CLIENT_CERTIFICATE_PATH=/path/to/cert.pem
AZURE_CLIENT_CERTIFICATE_PASSWORD=<optional-password>

# Authority (sovereign clouds)
AZURE_AUTHORITY_HOST=login.microsoftonline.com  # Default; or login.chinacloudapi.cn, login.microsoftonline.us

# User-assigned managed identity
AZURE_CLIENT_ID=<managed-identity-client-id>

# Credential selection (new)
AZURE_TOKEN_CREDENTIALS=dev|prod|<credential-name>  # Optional, restricts DAC chain
```

## Authentication & Lifecycle

> **🔑 Two rules apply to every code sample below:**
>
> 1. **Prefer `DefaultAzureCredential`.** It works locally (Azure CLI / VS Code / Developer CLI) and in Azure (managed identity, workload identity) with no code change. Avoid connection strings, account/API keys — they bypass Entra audit and rotation.
>    - Local dev: `DefaultAzureCredential` works as-is.
>    - Production: set `AZURE_TOKEN_CREDENTIALS=prod` (or `AZURE_TOKEN_CREDENTIALS=<specific_credential>`) to constrain the credential chain to production-safe credentials.
> 2. **Wrap credentials and clients in context managers** when they own token caches / transports:
>    - Sync: `with DefaultAzureCredential() as credential:`
>    - Async: `async with DefaultAzureCredential() as credential:` (from `azure.identity.aio`)
>
> Snippets may abbreviate this setup, but production code should always follow both rules.

### DefaultAzureCredential

The recommended credential for most scenarios. Tries multiple authentication methods in order:

```python
from azure.identity import DefaultAzureCredential
from azure.storage.blob import BlobServiceClient

# Works in local dev AND production without code changes
credential = DefaultAzureCredential()

with BlobServiceClient(
    account_url="https://<account>.blob.core.windows.net",
````
