Authentication with Azure Maps
Azure Maps supports two ways to authenticate requests: Shared Key and Azure Active Directory (Azure AD). This article explains these authentication methods to help guide your implementation.
Shared Key authentication
Shared Key authentication passes keys generated by an Azure Maps account with each request to Azure Maps. Two keys are generated when your Azure Maps account is created. For each request to Azure Maps services, the subscription key needs to be added as a parameter to the URL.
We recommend regenerating your keys regularly. You're provided with two keys so that you can maintain connections with one key while regenerating the other. When you regenerate your keys, you need to update any applications that access the account to use the new keys.
For information about viewing your keys, see View authentication details.
Authentication with Azure Active Directory (Preview)
Azure Maps now offers Azure Active Directory (Azure AD) integration for the authentication of requests for Azure Maps services. Azure AD provides identity-based authentication, including role-based access control (RBAC), to grant user-level or application-level access to Azure Maps resources. The sections that follow can help you understand the concepts and components of Azure Maps integration with Azure AD.
Authentication with OAuth access tokens
Azure Maps accepts OAuth 2.0 access tokens for Azure AD tenants associated with an Azure subscription that contains an Azure Maps account. Azure Maps accepts tokens for:
- Azure AD users.
- Partner applications that use permissions delegated by users.
- Managed identities for Azure resources.
Azure Maps generates a unique identifier (client ID) for each Azure Maps account. When you combine this client ID with additional parameters, you can request tokens from Azure AD by specifying the following value:
For more information about how to configure Azure AD and request tokens for Azure Maps, see Manage authentication in Azure Maps.
For general information about requesting tokens from Azure AD, see What is authentication?.
Request Azure Map resources with OAuth tokens
After a token is received from Azure AD, a request can be sent to Azure Maps with the following two required request headers set:
x-ms-client-id is the Azure Maps account-based GUID that appears on the Azure Maps authentication page.
Here's an example of an Azure Maps route request that uses an OAuth token:
GET /route/directions/json?api-version=1.0&query=52.50931,13.42936:52.50274,13.43872 Host: atlas.microsoft.com x-ms-client-id: 30d7cc….9f55 Authorization: Bearer eyJ0e….HNIVN
For information about viewing your client ID, see View authentication details.
Control access with RBAC
Azure AD lets you control access to secured resources by using RBAC. After you create your Azure Maps account and register your Azure Maps Azure AD application within your Azure AD tenant, you can set up RBAC for a user, application, or Azure resource on the Azure Maps account portal page.
Azure Maps supports read access control for individual Azure AD users, applications, and Azure services via managed identities for Azure resources.
For information about viewing your RBAC settings, see How to configure RBAC for Azure Maps.
Managed identities for Azure resources and Azure Maps
Managed identities for Azure resources provide Azure services (Azure App Service, Azure Functions, Azure Virtual Machines, and so on) with an automatically managed identity that can be authorized for access to Azure Maps services.
