README

Azure Identity client library for Go

The Azure Identity library provides a set of credential types for use with Azure SDK clients which support Azure Active Directory (AAD) token authentication.

Source code | Azure Active Directory documentation

Getting started

Install the package

Install the Azure Identity module:

go get -u github.com/Azure/azure-sdk-for-go/sdk/azidentity

Prerequisites

Authenticating during local development

When debugging and executing code locally it is typical for developers to use their own accounts for authenticating calls to Azure services. The Azure Identity library supports authenticating through developer tools to simplify local development.

Authenticating via the Azure CLI

DefaultAzureCredential and AzureCLICredential can authenticate as the user signed in to the Azure CLI. To sign in to the Azure CLI, run az login. On a system with a default web browser, the Azure CLI will launch the browser to authenticate a user.

Azure CLI Account Sign In

When no default browser is available, az login will use the device code authentication flow. This can also be selected manually by running az login --use-device-code.

Azure CLI Account Device Code Sign In

Key concepts

Credentials

A credential is a type which contains or can obtain the data needed for a service client to authenticate requests. Service clients across the Azure SDK accept a credential instance when they are constructed, and use that credential to authenticate requests.

The Azure Identity library focuses on OAuth authentication with Azure Active Directory (AAD). It offers a variety of credential types capable of acquiring an AAD access token. See Credential Types below for a list of this library's credential types.

DefaultAzureCredential

DefaultAzureCredential is appropriate for most applications which will run in the Azure Cloud because it combines common production credentials with development credentials. DefaultAzureCredential attempts to authenticate via the following mechanisms in this order, stopping when one succeeds:

DefaultAzureCredential authentication flow

  • Environment - DefaultAzureCredential will read account information specified via environment variables and use it to authenticate.
  • Managed Identity - if the application is deployed to an Azure host with Managed Identity enabled, DefaultAzureCredential will authenticate with it.
  • Azure CLI - If a user has signed in via the Azure CLI az login command, DefaultAzureCredential will authenticate as that user.

Credential Types

Authenticating Azure Hosted Applications
credential usage
DefaultAzureCredential simplified authentication to get started developing applications for the Azure cloud
ChainedTokenCredential define custom authentication flows composing multiple credentials
EnvironmentCredential authenticate a service principal or user configured by environment variables
ManagedIdentityCredential authenticate the managed identity of an Azure resource
Authenticating Service Principals
credential usage
ClientSecretCredential authenticate a service principal using a secret
CertificateCredential authenticate a service principal using a certificate
Authenticating Users
credential usage
InteractiveBrowserCredential interactively authenticate a user with the default web browser
DeviceCodeCredential interactively authenticate a user on a device with limited UI
UsernamePasswordCredential authenticate a user with a username and password
Authenticating via Development Tools
credential usage
AzureCLICredential authenticate as the user signed in to the Azure CLI

Environment Variables

DefaultAzureCredential] and EnvironmentCredential can be configured with environment variables. Each type of authentication requires values for specific variables:

Service principal with secret
variable name value
AZURE_CLIENT_ID id of an Azure Active Directory application
AZURE_TENANT_ID id of the application's Azure Active Directory tenant
AZURE_CLIENT_SECRET one of the application's client secrets
Service principal with certificate
variable name value
AZURE_CLIENT_ID id of an Azure Active Directory application
AZURE_TENANT_ID id of the application's Azure Active Directory tenant
AZURE_CLIENT_CERTIFICATE_PATH path to a PEM-encoded certificate file including private key (without password protection)
Username and password
variable name value
AZURE_CLIENT_ID id of an Azure Active Directory application
AZURE_USERNAME a username (usually an email address)
AZURE_PASSWORD that user's password

Configuration is attempted in the above order. For example, if values for a client secret and certificate are both present, the client secret will be used.

Troubleshooting

Error Handling

Credentials return CredentialUnavailableError when they're unable to attempt authentication because they lack required data or state. For example, NewEnvironmentCredential will return an error when its configuration is incomplete.

Credentials return AuthenticationFailedError when they fail to authenticate. Call Error() on AuthenticationFailedError to see why authentication failed. When returned by DefaultAzureCredential or ChainedTokenCredential, the message collects error messages from each credential in the chain.

For more details on handling specific Azure Active Directory errors please refer to the Azure Active Directory error code documentation.

Logging

This library uses the classification based logging implementation in azcore. To turn on logging set AZURE_SDK_GO_LOGGING to all. If you only want to include logs for azidentity, you must create you own logger and set the log classification as LogCredential. Credentials log basic information only, including GetToken success or failure and errors. These log entries do not contain authentication secrets but may contain sensitive information.

To obtain more detailed logging, including request/response bodies and header values, make sure to leave the logger as default or enable the LogRequest and/or LogResponse classificatons. A logger that only includes credential logs can be like the following:

// Set log to output to the console
azcore.Log().SetListener(func(cls LogClassification, s string) {
		fmt.Println(s) // printing log out to the console
  })
  
// Include only azidentity credential logs
azcore.Log().SetClassifications(azidentity.LogCredential)

CAUTION: logs from credentials contain sensitive information. These logs must be protected to avoid compromising account security.
