Added the Azure.MixedReality.Authentication library (#16714)
This change adds an authentication library for Mixed Reality services, which all currently utilize a custom STS for authentication. Upcoming Mixed Reality client libraries will depend on this library to perform authentication using identities from Azure.Identity. See the added README.md for more information about the library.

# Azure Mixed Reality Authentication Package client library for Python | ||
|
||
Mixed Reality services, like Azure Spatial Anchors, Azure Remote Rendering, and others, use the Mixed Reality security | ||
token service (STS) for authentication. This package supports exchanging Mixed Reality account credentials for an access | ||
token from the STS that can be used to access Mixed Reality services. | ||
|
||
![Mixed Reality service authentication diagram](https://docs.microsoft.com/azure/spatial-anchors/concepts/media/spatial-anchors-authentication-overview.png) | ||
|
||
# Getting started | ||
|
||
## Currently supported environments | ||
|
||
This package has been tested with Python 2.7, 3.5, 3.6, 3.7, 3.8, and 3.9. | ||
|
||
## Prerequisites | ||
|
||
- An [Azure subscription][azure_sub]. | ||
- You must have an account with an [Azure Mixed Reality service](https://azure.microsoft.com/topic/mixed-reality/): | ||
- [Azure Remote Rendering](https://docs.microsoft.com/azure/remote-rendering/) | ||
- [Azure Spatial Anchors](https://docs.microsoft.com/azure/spatial-anchors/) | ||
- Familiarity with the authentication and credential concepts from the [Azure Identity library][azure_identity]. | ||
- Python 2.7, or 3.5 or later is required to use this package. | ||
|
||
## Install the package | ||
|
||
Install the Azure Mixed Reality Authentication SDK. | ||
|
||
```bash | ||
pip install --pre azure-mixedreality-authentication | ||
``` | ||
|
||
## Create and authenticate a `MixedRealityStsClient` | ||
|
||
To create a client object to request an access token for a Mixed Reality service, you will need the `account identifier` | ||
and `account domain` of your Mixed Reality service resource and a `credential`. | ||
|
||
Mixed Reality services support a few different forms of authentication: | ||
|
||
- Account Key authentication | ||
- Account keys enable you to get started quickly with using Mixed Reality services. But before you deploy your application | ||
to production, we recommend that you update your app to use Azure AD authentication. | ||
- Azure Active Directory (AD) token authentication | ||
- If you're building an enterprise application and your company is using Azure AD as its identity system, you can use | ||
user-based Azure AD authentication in your app. You then grant access to your Mixed Reality accounts by using your | ||
existing Azure AD security groups. You can also grant access directly to users in your organization. | ||
- Otherwise, we recommend that you obtain Azure AD tokens from a web service that supports your app. We recommend this | ||
method for production applications because it allows you to avoid embedding the credentials for access to a Mixed | ||
Reality service in your client application. | ||
|
||
See [here][register_aad_app] for detailed instructions and information. | ||
|
||
### Using account key authentication | ||
|
||
Use the [Azure Portal][azure_portal] to browse to your Mixed Reality service resource and retrieve an `account key`. | ||
|
||
Once you have an account key, you can use the `AzureKeyCredential` class to authenticate the client as follows: | ||
|
||
```python | ||
from azure.core.credentials import AzureKeyCredential | ||
from azure.mixedreality.authentication import MixedRealityStsClient | ||
|
||
account_id = "<ACCOUNTD ID>" | ||
account_domain = "<ACCOUNT_DOMAIN>" | ||
account_key = "<ACCOUNT_KEY>" | ||
key_credential = AzureKeyCredential(account_key) | ||
|
||
client = MixedRealityStsClient(account_id, account_domain, key_credential) | ||
``` | ||
|
||
> Note: Account key authentication is **not recommended** for production applications. | ||
### Using an Azure Active Directory Credential | ||
|
||
Account key authentication is used in most of the examples, but you can also authenticate with Azure Active Directory | ||
using the [Azure Identity library][azure_identity]. This is the recommended method for production applications. To use | ||
the [DefaultAzureCredential][defaultazurecredential] provider shown below, or other credential providers provided with | ||
the Azure SDK, please install the `@azure/identity` package: | ||
|
||
You will also need to [register a new AAD application][register_aad_app] and grant access to your Mixed Reality resource | ||
by assigning the appropriate role for your Mixed Reality service to your service principal. | ||
|
||
```python | ||
from azure.identity import DefaultAzureCredential | ||
from azure.mixedreality.authentication import MixedRealityStsClient | ||
|
||
account_id = "<ACCOUNTD ID>" | ||
account_domain = "<ACCOUNT_DOMAIN>" | ||
default_credential = DefaultAzureCredential() | ||
|
||
client = MixedRealityStsClient(account_id, account_domain, default_credential) | ||
``` | ||
|
||
# Key concepts | ||
|
||
## MixedRealityStsClient | ||
|
||
The `MixedRealityStsClient` is the client library used to access the Mixed Reality STS to get an access token. An access | ||
token can be retrieved by calling `get_token()` on an `MixedRealityStsClient` instance. | ||
|
||
Tokens obtained from the Mixed Reality STS have a lifetime of **24 hours**. | ||
|
||
### Token result value | ||
|
||
The return value for a successful call to `get_token` is an `azure.core.credentials.AccessToken`. | ||
|
||
See the authentication examples [above](#authenticate-the-client) or [Azure Identity][azure_identity] for more complex | ||
authentication scenarios. | ||
|
||
## Retrieve an access token synchronously | ||
|
||
```python | ||
from azure.core.credentials import AzureKeyCredential | ||
from azure.mixedreality.authentication import MixedRealityStsClient | ||
|
||
account_id = "<ACCOUNTD ID>" | ||
account_domain = "<ACCOUNT_DOMAIN>" | ||
account_key = "<ACCOUNT_KEY>" | ||
key_credential = AzureKeyCredential(account_key) | ||
|
||
client = MixedRealityStsClient(account_id, account_domain, key_credential) | ||
|
||
token = client.get_token() | ||
``` | ||
|
||
## Retrieve an access token asynchronously | ||
|
||
```python | ||
from azure.core.credentials import AzureKeyCredential | ||
from azure.mixedreality.authentication.aio import MixedRealityStsClient | ||
|
||
account_id = "<ACCOUNTD ID>" | ||
account_domain = "<ACCOUNT_DOMAIN>" | ||
account_key = "<ACCOUNT_KEY>" | ||
key_credential = AzureKeyCredential(account_key) | ||
|
||
client = MixedRealityStsClient(account_id, account_domain, key_credential) | ||
|
||
token = await client.get_token() | ||
``` | ||
|
||
# Examples | ||
|
||
These are code samples that show common scenario operations with the Azure Mixed Reality Authentication client library. | ||
The async versions of the samples (the python sample files appended with `_async`) show asynchronous operations, | ||
and require Python 3.5 or later. | ||
Before running the sample code, refer to Prerequisites | ||
<!-- [Prerequisites](#Prerequisites) --> | ||
to create a resource, then set some Environment Variables | ||
|
||
```bash | ||
set MIXEDREALITY_ACCOUNT_DOMAIN="<the Mixed Reality account domain>" | ||
set MIXEDREALITY_ACCOUNT_ID="<the Mixed Reality account identifier>" | ||
set MIXEDREALITY_ACCOUNT_KEY="<the Mixed Reality account primary or secondary key>" | ||
|
||
pip install azure-mixedreality-authentication | ||
|
||
python samples\client_sample.py | ||
python samples\client_sample_async.py | ||
``` | ||
|
||
