Microsoft Azure Mixed Reality Authentication Client Library for Python

Azure Mixed Reality Authentication Package client library for Python

Deprecation notice

This package has been deprecated and will no longer be maintained after 10-01-2025. This package will only receive security fixes until 10-01-2025.

Overview

Mixed Reality services, like Azure Remote Rendering 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.

Getting started

Currently supported environments

This package has been tested with Python 3.7+.

Prerequisites

• An Azure subscription.
• You must have an account with an Azure Mixed Reality service:
  • Azure Remote Rendering
• Familiarity with the authentication and credential concepts from the Azure Identity library.
• Python 3.7 or later is required to use this package.

Install the package

Install the Azure Mixed Reality Authentication SDK.

pip install --pre azure-mixedreality-authentication

Create and authenticate the client

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 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:

from azure.core.credentials import AzureKeyCredential
from azure.mixedreality.authentication import MixedRealityStsClient

account_id = "<ACCOUNT_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. This is the recommended method for production applications. To use the 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.

from azure.identity import DefaultAzureCredential
from azure.mixedreality.authentication import MixedRealityStsClient

account_id = "<ACCOUNT_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 or Azure Identity for more complex authentication scenarios.

Retrieve an access token synchronously

from azure.core.credentials import AzureKeyCredential
from azure.mixedreality.authentication import MixedRealityStsClient

account_id = "<ACCOUNT_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

from azure.core.credentials import AzureKeyCredential
from azure.mixedreality.authentication.aio import MixedRealityStsClient

account_id = "<ACCOUNT_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

to create a resource, then set some Environment Variables

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

Troubleshooting

The troubleshooting section for Azure Identity can be helpful when troubleshooting authentication issues.
