EmpowerID enables legacy .NET web applications to transition into Azure authentication through its easy-to-use plugin modules. The transformation into Azure AD can happen with little or no code changes to your legacy apps. The plugins can pre-process requests, user claims transformation, and identity generation, which occurs before your application receives and processes the HTTP request.
