PassCore is a very simple 1-page web application written in C#, using ASP.NET 5, Angular Material, Angular and Microsoft Directory Services. It allows users to change their Active Directory password on their own, provided the user is not disabled.PassCore does not require any configuration, as it obtains the principal context from the current domain. I wrote this because a number of people have requested several features that the original version did not have. The original version of this tool was downloaded around 8000 times in 2.5 years. My hope is that the new version continues to be just as popular. There really is no free alternative out there (that I know of) so hopefully this saves someone else some time and money.
