The custom authentication extension supports the on attribute collection start event. This event occurs
at the beginning of the attribute collection step, before the attribute collection page renders. You can add
actions
such as prefilling values and displaying a blocking error. This demo shows how to prepopulate some of the
values, including pre selecting the country attribute with Spain
and generating and set the value of the promo code attribute.
Start by registering a custom authentication extension that is used by Microsoft Entra ID to
call
your REST API.
The custom authentication extension contains information about your REST API endpoint, the
attribute collection start action that it parses from your REST API, and how to
authenticate to your REST API.
Sign in to the Microsoft Entra admin center
and browse to External Identities > Custom authentication extensions.
Note, you can also browse to Applications > Enterprise applications > Custom
authentication extensions .
Then, select
Create a custom extension.
In Basics, select the AttributeCollectionStart
event, and then select Next.
In Endpoint Configuration, fill in the following properties:
Name - A name for your custom authentication extension. For example,
Prepopulate sign-up attributes.
Target URL - The URL of your REST API.
Timeout in milliseconds - The maximum number of retries the API endpoint will be
called
in case of failure. If empty, will default to service default.
Maximum Retries - The maximum number of retries the API endpoint will be called in
case
of failure. If empty, will default to service default..
Description - A description for your custom authentication extensions.
To continue, select Next.
To ensure the communications between the custom authentication extension and your REST API are
secured appropriately, multiple security controls must be applied. The first step is to create
or
choose an application that Microsoft Entra ID uses the OAuth 2.0 client credentials grant flow
to
secure the
call to your API endpoint.
If this is your first custom authentication extension, see how we have configured
our TokenIssuanceStart event.
Since we already configured a custom authentication extension, in API Authentication,
choose the Select an existing app registration in this directory option.
Select the application you configured for the other custom authentication extensions, and choose
Select.
Review your configuration and select Create, which registers the custom authentication
extension and the associated application registration
you selected.
At this point the custom authenticate extension is configured in your tenant, but not in used in
any
of the sign-up pages.
Next you associate the custom authentication extension with one or more of your user flows.
To do so, browse to Identity > External Identities > User flows.
Then, select the user flow from the list.
From the menu, select Custom authentication extensions. To associate your custom
authentication
extension, select the Before collecting information from the user event.
The custom extensions configured for the
OnAttributeCollectionStart event will be displayed.
Select one of them for the attribute collection start event, and then choose Select and
then
save the changes.
Well done!
You created a custom authentication extension type of OnAttributeCollectionStart. Then
you associated it with your user flow. To check the user experience, sign-up to your
application.
Next, you register the custom authentication extension.
You register the custom authentication extension by
associating it with the Custom authentication extension security app you created, and to your
REST API endpoint. Replace:
{app-ID} with the app ID from the previous call Custom authentication extension security
app.
{REST-API-domain} with your rest API domain name
{Endpoint-URL} - with the RUL of your REST API endpoint
POST https://graph.microsoft.com/beta/identity/customAuthenticationExtensions
From the response, copy the value of the id. For example:
{
"@odata.context": "https://graph.microsoft.com/beta/$metadata#identity/customAuthenticationExtensions/$entity",
"@odata.type": "#microsoft.graph.onAttributeCollectionSubmitCustomExtension",
"id": "22222222-2222-3333-3333-444444444444",
"displayName": "Validate sign-up user input",
"description": "Validate user input including the city name and may ask the user to correct the data or block the user",
}
2.2 Create authentication event listener
After you register you registered your custom authentication extension, create authentication event listener.
In the next JSON, replace the {Custom-auth-extension-ID} with the custom authentication extension you
just created.
POST https://graph.microsoft.com/beta/identity/authenticationEventListeners
{Custom-auth-extension-ID} with the custom authentication extension you just created.
PUT https://graph.microsoft.com/beta/identity/authenticationEventsFlows/{user-flow-ID}/microsoft.graph.externalUsersSelfServiceSignUpEventsFlow/onAttributeCollectionStart/microsoft.graph.onAttributeCollectionStartCustomExtensionHandler/customExtension/$ref
PUT https://graph.microsoft.com/beta/identity/authenticationEventsFlows/44444444-4444-4444-4444-445555555555/microsoft.graph.externalUsersSelfServiceSignUpEventsFlow/onAttributeCollectionStart/microsoft.graph.onAttributeCollectionStartCustomExtensionHandler/customExtension/$ref

Single sign-on (SSO) adds security and convenience when users sign-in across multiple applications
in Microsoft Entra ID.
With single sign-on, users sign-in once with a single account and get access to multiple
applications.
When the user initially signs-in to an application, Microsoft Entra ID initiates a single sign-on
session.
Upon subsequent authentication requests, Microsoft Entra ID validates the session, and issues a
security token without prompting the user to sign in again.
For tests only! You can specify the lifetime of an access token, ID token, or SAML token
issued by the Microsoft
Entra ID. You can set token lifetimes for all apps in your tenant, or for service principals. You
cannot set token lifetime policies for refresh tokens and session tokens.

Input-constrained devices are devices that their screen or monitor is limited to
text-only and they don't have a web browser. For example, smart TV, IoT device, robot,
gaming console, printers. Or applications with limited user interface, such as a command
line application.
These devices are connected to the internet, but due to the input constrains, the
authentication should be done on another device. The input constrained device gets a
device code from Microsoft Entra External ID and asks the user to visit a webpage in a browser
on a second
(rich device), such as smartphone, tablets, or PCs.
In this use case, from the Kiosk page select sign-in. Use the second device, such as
smartphone and scan the QR code. On the sign-in page enters the device code, and
completes the sign-in. Once you signed in, the Kiosk (input-constrained device) is able
