Question

Asp.Net web application with Token implementation

Selvakumar Ramachandran 1

Hi,

In my Asp.Net (aspx) web application, we are using form based authentication. As part of modernization, we are asked to move to token based authentication. How will I enable token based authentication in my application without impacting the current functionality. We are using role based authorization as well.

Please give me an idea how to migrate our application to token based authentication.

Thank you

You'll continue to used Web Forms authentication/authorization which is just a cookie. What changes is the authentication process. Rather than using your current authentication processes you'll authenticate with the (unknown) token server. Once authenticated, your Web Forms application logic populates the forms auth ticket and add whatever roles are required for your application to function properly.

Implement forms-based authentication in an ASP.NET application by using C#.NET

If your new token server is a well-known service like Azure AD then the above logic is probably handled by a library that you can install from NuGet. Read the token server documentation so you have an understanding of how your application is affected and what steps you need to perform.

Hi @Selvakumar Ramachandran

First, authentication methods typically don't conflict with your application. Web Forms authentication is usually validated in the form of cookies.

As for how to migrate your application to token-based authentication. The first thing to look at is how the token is validated. Each token has its own unique way of programming. The second thing to see is whether the token supports your framework.

These things are required according to the certificate documentation.

I think the following documentation will be helpful to you.

Form Authentication.

Finally, I would like to say that there is a problem with the functional impact during the migration process. My conclusion above is that there is basically no impact. However, it is not excluded that some data is shared by your function and validation. So I think it's important to test your code well before migrating.
