Sign in to Azure PowerShell interactively

  • Artikel

Interactive logins to Azure offer a more intuitive and flexible user experience. Interactive login with Azure PowerShell allows users to authenticate to Azure directly through the PowerShell interface, which is useful for ad-hoc management tasks and for environments that require manual sign-in, such as those with multifactor authentication (MFA). This method simplifies access for script testing, learning, and on-the-fly management without needing to preconfigure service principals or other noninteractive authentication methods.

Important

Beginning in early 2025, Azure PowerShell sign-ins using interactive authentication require multi-factor authentication (MFA). For more information, see Planning for mandatory multi-factor authentication for Azure and other admin portals.

Prerequisites

Interactive login

To sign in interactively, use the Connect-AzAccount cmdlet. Beginning with Az PowerShell module version 12.0.0, Windows systems use Web Account Manager (WAM), and Linux and macOS systems use browser-based login by default.

Connect-AzAccount

Login experience

Beginning with Az PowerShell module version 12.0.0, if you have access to multiple subscriptions, you're prompted to select an Azure subscription to login with, as shown in the following example.

Please select the account you want to login with.

WARNING: To override which subscription Connect-AzAccount selects by default, use
`Update-AzConfig -DefaultSubscriptionForLogin 00000000-0000-0000-0000-000000000000`.

The next time you login, the previously selected tenant and subscription is marked as the default with an asterisk (*) next to its number and highlighted in a cyan blue color. This allows you to press Enter to select the default or type a number to select a different tenant and subscription.

Commands run against this subscription by default. To change your active subscription, use the Set-AzContext cmdlet. For more information, see Azure PowerShell context objects.

Configure your default subscription for login

To prevent being prompted to select a subscription each time you log in interactively, use the Update-AzConfig cmdlet to set your default subscription, as shown in the following example.

Update-AzConfig -DefaultSubscriptionForLogin '<subscription name or id>'

Disable the new login experience

To disable the new login experience, use the Update-AzConfig cmdlet, as shown in the following example.

Update-AzConfig -LoginExperienceV2 Off

When the new login experience is disabled and you have access to multiple subscriptions, you're signed in to the first subscription Azure returns. Commands run against this subscription by default. To change your active subscription for a session, use the Set-AzContext cmdlet. To change your active subscription and have it persist between sessions on the same system, use the Select-AzContext cmdlet.

Web Account Manager (WAM)

Beginning with Az PowerShell module version 12.0.0, Azure PowerShell's default login authentication method for Windows-based systems is Web Account Manager (WAM).

WAM is a Windows 10+ component that acts as an authentication broker. An authentication broker is an application that runs on your system that manages the authentication handshakes and token maintenance for connected accounts.

Benefits of WAM

Using WAM offers several benefits:

Limitations of WAM

At the current stage of development, there are a few known limitations to WAM:

  • WAM is available on Windows 10 and later and on Windows Server 2019 and later. On Linux, macOS, and earlier versions of Windows, Azure PowerShell automatically defaults to browser-based login.

  • Using WAM to log in to national clouds isn't currently supported.

  • Microsoft Accounts (for example, @outlook.com or @live.com) must specify the Tenant parameter when used with MFA.

    Connect-AzAccount -Tenant 00000000-0000-0000-0000-000000000000

Disable WAM

To use browser-based login on Windows 10 and later or on Windows Server 2019 and later with Az 12.0.0 and higher, you must disable WAM for use with Azure PowerShell. Use the following command to disable WAM and return to browser-based login, the default before Az 12.0.0.

Update-AzConfig -EnableLoginByWam $false

Browser-based login

Browser-based login is the default interactive login for Linux, macOS, and Windows systems older than Windows 10 or Windows Server 2019. Beginning with Az PowerShell module version 12.0.0, you must disable WAM for Azure PowerShell to use browser-based login on Windows-based systems, which was the default before Az 12.0.0.

When you sign in interactively with the Connect-AzAccount cmdlet, browser-based login opens the default web browser to load an Azure sign-in page. Sign in with your Azure account credentials in the browser.

If Azure PowerShell can open your default browser, it initiates authorization code flow and opens the default browser to load an Azure sign-in page. Otherwise, it initiates device code flow, which instructs you to open a browser page at microsoft.com/devicelogin and enter the code displayed in your PowerShell session.

Device code authentication

If Web Account Manager or a web browser is unavailable or it fails to open, you can force device code flow by specifying the UseDeviceAuthentication parameter.

Connect-AzAccount -UseDeviceAuthentication

Sign in to a different tenant

If your account is associated with more than one tenant, sign-in requires the Tenant parameter to be specified when connecting. This parameter works with any sign-in method. When logging in, this parameter value can either be the Azure object ID of the tenant (Tenant ID) or the fully qualified domain name of the tenant.

Connect-AzAccount -Tenant 00000000-0000-0000-0000-000000000000

Sign in to a national cloud

National clouds (also known as sovereign clouds) are physically isolated instances of Azure designed to ensure data residency, sovereignty, and compliance requirements are honored within geographical boundaries. For accounts in a national cloud, set the environment when you sign in using the Environment parameter. This parameter works with any sign-in method. For example, if your account is in Azure China 21Vianet, use the following command:

Connect-AzAccount -Environment AzureChinaCloud

You can get a list of available national cloud environments by running the following command:

Get-AzEnvironment | Select-Object -Property Name
