UserManager.FindAsync(username, password) not available in ASP.NET 5 / Identity 3

Question

I'm trying to upgrade a project to ASP.NET 5 / MVC 6.

The UserManager that came with AspNet.Identity used to have a FindAsync method where I could pass in a username and password. It doesn't seem to be there anymore.

I don't think I need the SigninManager or Authentication as I'm using JWT Bearer Authentication. I just need to check the username and password are valid before I grant an access token,

Answer 1

Simply use UserManager.FindByNameAsync() to find the user object then check its password:

var user = await _userManager.FindByNameAsync(userName);
if(user!=null && await _userManager.CheckPasswordAsync(user, password))
{
    // user is valid do whatever you want
}
