Web app that signs in users: App registration
This article explains the app registration steps for a web app that signs in users.
To register your application, you can use:
- The web app quickstarts. In addition to being a great first experience with creating an application, quickstarts in the Azure portal contain a button named Make this change for me. You can use this button to set the properties you need, even for an existing app. Adapt the values of these properties to your own case. In particular, the web API URL for your app is probably going to be different from the proposed default, which will also affect the sign-out URI.
- The Azure portal to register your application manually.
- PowerShell and command-line tools.
Register an app by using the quickstarts
You can use the following link to bootstrap the creation of your web application:
Register an app by using the Azure portal
Tip
Steps in this article might vary slightly based on the portal you start from.
Note
The portal to use is different depending on whether your application runs in the Microsoft Azure public cloud or in a national or sovereign cloud. For more information, see National clouds.
- Sign in to the Microsoft Entra admin center.
- If you have access to multiple tenants, use the Settings icon
in the top menu to switch to the tenant in which you want to register the application from the Directories + subscriptions menu.
- Browse to Identity > Applications > App registrations, select New registration.
- When the Register an application page appears, enter your application's registration information:
- Enter a Name for your application, for example
AspNetCore-WebApp
. Users of your app might see this name, and you can change it later. - Choose the supported account types for your application. (See Supported account types.)
- For Redirect URI, add the type of application and the URI destination that will accept returned token responses after successful authentication. For example, enter
https://localhost:44321
. - Select Register.
- Enter a Name for your application, for example
- Under Manage, select Authentication and then add the following information:
- In the Web section, add
https://localhost:44321/signin-oidc
as a Redirect URI. - In Front-channel logout URL, enter
https://localhost:44321/signout-oidc
. - Under Implicit grant and hybrid flows, select ID tokens.
- Select Save.
- In the Web section, add
Register an app by using PowerShell
You can also register an application with Microsoft Graph PowerShell, using the New-MgApplication.
Here's an idea of the code. For a fully functioning code, see this sample
# Connect to the Microsoft Graph API, non-interactive is not supported for the moment (Oct 2021)
Write-Host "Connecting to Microsoft Graph"
if ($tenantId -eq "") {
Connect-MgGraph -Scopes "User.Read.All Organization.Read.All Application.ReadWrite.All" -Environment $azureEnvironmentName
}
else {
Connect-MgGraph -TenantId $tenantId -Scopes "User.Read.All Organization.Read.All Application.ReadWrite.All" -Environment $azureEnvironmentName
}
$context = Get-MgContext
$tenantId = $context.TenantId
# Get the user running the script
$currentUserPrincipalName = $context.Account
$user = Get-MgUser -Filter "UserPrincipalName eq '$($context.Account)'"
# get the tenant we signed in to
$Tenant = Get-MgOrganization
$tenantName = $Tenant.DisplayName
$verifiedDomain = $Tenant.VerifiedDomains | where {$_.Isdefault -eq $true}
$verifiedDomainName = $verifiedDomain.Name
$tenantId = $Tenant.Id
Write-Host ("Connected to Tenant {0} ({1}) as account '{2}'. Domain is '{3}'" -f $Tenant.DisplayName, $Tenant.Id, $currentUserPrincipalName, $verifiedDomainName)
# Create the webApp AAD application
Write-Host "Creating the AAD application (WebApp)"
# create the application
$webAppAadApplication = New-MgApplication -DisplayName "WebApp" `
-Web `
@{ `
RedirectUris = "https://localhost:44321/", "https://localhost:44321/signin-oidc"; `
HomePageUrl = "https://localhost:44321/"; `
LogoutUrl = "https://localhost:44321/signout-oidc"; `
} `
-SignInAudience AzureADandPersonalMicrosoftAccount `
#end of command
$currentAppId = $webAppAadApplication.AppId
$currentAppObjectId = $webAppAadApplication.Id
$tenantName = (Get-MgApplication -ApplicationId $currentAppObjectId).PublisherDomain
#Update-MgApplication -ApplicationId $currentAppObjectId -IdentifierUris @("https://$tenantName/WebApp")
# create the service principal of the newly created application
$webAppServicePrincipal = New-MgServicePrincipal -AppId $currentAppId -Tags {WindowsAzureActiveDirectoryIntegratedApp}
# add the user running the script as an app owner if needed
$owner = Get-MgApplicationOwner -ApplicationId $currentAppObjectId
if ($owner -eq $null)
{
New-MgApplicationOwnerByRef -ApplicationId $currentAppObjectId -BodyParameter = @{"@odata.id" = "htps://graph.microsoft.com/v1.0/directoryObjects/$user.ObjectId"}
Write-Host "'$($user.UserPrincipalName)' added as an application owner to app '$($webAppServicePrincipal.DisplayName)'"
}
Write-Host "Done creating the webApp application (WebApp)"
