What are the possibilities of squaring a API web service with Azure?

Question

I have some web products published as web api services for public and organizations and run on different platforms. Now I am interested to migrating them to Azure.
Most of the services are developed under asp.net(framework 4.7.0) with owin(tokenized) authentication. For the testing purpose I hosted my sample api in the VM under my azure subscription, It is working without any azure authentication.

My API apps on Azure as per the client interest should authenticate Azure AD or other secure authentication services provided by azure and the same build must works as it is now on other platforms. the solution must be compatible for asp.net - framework 4.7(not asp.netcore) and should keep the existing authentication(tokenization) process

It should be achieved without source code modification, using only configuration or simple code change. If it is possible, I need your straight forward instructions to migrate my apps to azure fast. I am not familiar in Azure also I have not time to searching azure encyclopedia or doing R and D work.

So I expecting proper step by step instructions.

Thankyou

Hi,

If you want to add authentication to your app without changing the code, you can use in Azure Web App and configure Azure AD authentication
