Today, we are releasing the final version of ASP.NET Identity 2.0. The main focus in this release was to add security and account management features as well as address feedback from the community.
Great news. Who've worked with version 1.0 of ASP.NET Identity is going to applaud. Great improvements in version 2.0.
