I’ve released version 1.0 of UmbracoIdentity which allows for ASP.Net Identity to be used with Umbraco for front-end members. I’ve tried to write enough documentation for you to get started, all of the code and docs are here: https://github.com/Shandem/UmbracoIdentity
It’s worth noting that this is not something that ‘everyone’ should just jump in with and start using. If you are not familiar with OWIN or ASP.Net Identity than none of this will really make any sense, I’ve added a bit of a disclaimer to the docs about this here: https://github.com/Shandem/UmbracoIdentity#owin-setup
There are some known issues and limitations that you should be aware of, and this will also not work currently with back office users (that will come eventually too though).
This package can be highly customized, it comes with many .cshtml views and c# classes that you can customize as you see fit – very similar to the Visual Studio 2013 Web Application templates that support ASP.Net Identity.
What about Asp.Net Membership with Umbraco?
The way that I’ve created this is to be 100% compatible with the current Membership structure in Umbraco. This means that this is not using EntityFramework to access data, it uses the Umbraco member services and providers using custom ASP.Net Identity user stores. This also means that the password formats are based on the current password formats of the membership provider. When the Nuget package is installed it will actually swap out the membership provider for a custom type: UmbracoIdentity.IdentityEnabledMembersMembershipProvider. This is required so that the password security can still be handled by the membership provider logic.
There is a note about passwords here, ASP.Net Identity normally will format and salt passwords different (slightly better) than how the membership providers current work, but if you need that functionality you’d have to implement your own IPasswordHasher.
It is absolutely essential you read the documentation before installing. Once you’ve done that, you can use Nuget:
PM> Install-Package UmbracoIdentity
