I have registered an application in Azure AD portal for oauth and working fine with my web application www.test.com.I have a concern that , the token generated by the client id and secret can be used in another application say www.otherapp.com.Is there any way to restrict that the app can only be used by www.test.com.
Unfortunately, there is currently no way to limit the Azure AD App to your application. If you are concerned that other users in the tenant will use the Azure AD app that you have registered, you can set the application to only specific users. You can Refer to this here.

We have an Azure AD B2C registered web app and an Azure AD registered Web API - is it possible to make authenticated calls to the Azure AD Web API from the Azure B2C Web app? Can it be done?
We have tried a few different ways but not having much luck - including Access Control Lists but it doesn't accept the token passed as says it is invalid.
You must register two applications in the Azure AD B2C directory to enable your app to sign in with Azure AD B2C and call a web API.
Your app can sign in with Azure AD B2C via the web, mobile, or SPA application registration. The Application ID, also known as the client ID, is generated during the app registration process and uniquely identifies your application (for example, App ID: 1).
Your app can use the web API registration to call a protected web API. - The web API permissions (scopes) are exposed as part of the registration . The Application ID is generated during the app registration process, and it uniquely identifies your web API (for example, _App ID: 2 ).

We are developing a multi-tenant application that is hosted in Azure. We're using IdentityServer4 for handling authentication and authorization. Recently, we enabled the SSO by registering our application in Azure AD. We enabled the multi-tenant SSO in the App registration service. The SSO works fine and client users can sign in with their Azure AD.
The users are accessing the application by providing the URL in the following format https://myapplication.com/mytenant. When a user logs in for the first time consent is required and if accepted the user can successfully log into its tenant space.
After the first successful access, our application is added to the My Apps portal in Azure.
Our problem is that the URL in My Apps is pointing to the one provided in the Branding tab in App registration but not the one that the user logged in for the first time. Since this is a multitenant application every tenant has its own URL.
Is it possible for the first sign-in URL to be saved in the My Apps portal? We can do an Azure tenant - application tenant sync based on claims but that means a lot of trouble just for accessing the My Apps portal.
An administrator of each customer could add a linked "single sign-on" app in their organization and assign it to users, but there's no way to have your single multi-tenant app present in different tenants with different URLs.
What you could do instead is to have your (only) sign-in URL be a URL that triggers a sign-in (generically, on the "common" or "organizations" endpoint, instead of a tenant-specific endpoint). Once the user has signed in, then you'll know what tenant the user belongs to, and you could redirect them to the appropriate version of your site.
I have an already deployed application on azure app service which uses azure AD for authentication and authorization.
Unfortunately the developer who worked on it is no longer available
i got access to all Azure resources and source code but i cant figure out how can i add my azure account as one of the users to the app (i can login but its an empty view for me unlike what it used to be with the developer access).
Also i find the app registered on Azure AD and i am an owner there but still with no right access.
When i try to login localy from the frontend it say
Selected user account does not exist in tenant 'Default Directory' and
cannot access the application '[some numbers] in that tenant. The
account needs to be added as an external user in the tenant first. Please use a
different account.
Would appreciate any help and many thanks in advance.

This is because your backend application is enabled with Azure AD Authentication.
After you sign in to your front-end application, you still can't access the data from the back-end app, because the back-end app now requires Azure Active Directory sign-in from the front-end app
To access the application, follow the below steps:
Grant the front-end access to the back end
Configure App Service to return a usable token
Use the token in your code
You can refer Enable authentication and authorization for front-end app in Authenticate users E2E - Azure App Service | Microsoft Docs for the detailed steps
I am using Custom Policies on Azure B2C.
When I want to run the Custom Policy I can choose the application which I want to use with the policy. I saw that I'm not only able to use my applications from Azure B2C, I can use the applications from the App Registration section.
What is the differences. I've been able to signup and sign in users with both types of applications.
Thanks in advance!
The two sets of apps are completely independent of each other.
You should not be able to see any of the Azure AD B2C apps in the Application Registration in Azure Active directory.Also, the apps in the Application Registration should not be visible in the B2C .
In your issue , I assume that you should have add two apps in the two places.
What is the differences.
Application in Azure AD B2C :To build an application that accepts consumer sign-up and sign-in, you first need to register the application with an Azure Active Directory B2C tenant.
Application Registration in Azure AD: This creates an Application ID for the application, and enables it to receive tokens. In order to get a client ID and secret from Azure, you have to register the app and provide some basic information about it, including what resources your app wants to access, and what permissions it needs.
Depending on your scenario, you could register an application in both portals, and use the right one depending on the request you need to make.
The apps that are registered through each different location (Azure Active AD versus Azure AD B2C) are given credentials that are valid for any policy, including custom policies you have uploaded.
The end result is the same: you have an application that is registered with and can access the policy regardless of how that app/policy was created.
We have chosen Azure AD for authenticating users for the Enterprise Web applications developed using MVC and hosted on Azure Cloud Platform.
We are trying to plan & develop a common portal for the users to which they can login using Azure AD login screen. This Portal will display the links to the cloud applications to which the user has access and they could access the cloud application from this portal.
Please let me know whether this is feasible since I have read in many places that the Azure AD token assigned to the user from Azure AD is valid only for one resource or registered application. Does that mean that when they try to login into another Cloud application registered to the same Azure AD from the portal, they will need to login again or re-use the Azure AD token for the portal in the browser session cookie for logging into the other applications?
It's true that your users authenticate against an application registered in Azure AD and that the issued token is only valid for that application.
However, the user establishes a session with the authorization server (Azure AD) and will not be prompted for credentials when redirected there to authenticate against another registered application.
So your portal page can just contain links to the URLs for the applications. Each application redirects the user to Azure AD for authentication and the user is only prompted for credentials for the first application he/she logs in to.
