Useful tips and tricks for programmers

When you migrate your project from ASP.NET MVC version 4 or earlier you may want to allow the users of your web application to log in with their current passwords without the necessity to reset the password or re-register. This article describes how to process the password hashes created in old ASP.NET Membership library.


By default, ASP.NET Core Identity has very strong password policies for the users. This is not always convenient, especially during development and testing. Here we will describe how to configure those policies to make it possible to use even simple and "weak" passwords while your application is not in production mode.
