ASP.NET Identity reset password

Question

How can I get the password of a user in the new ASP.NET Identity system? Or how can I reset without knowing the current one (user forgot password)?

This was the original answer. It does work, but has a problem. What if AddPassword fails? The user is left without a password.

The original answer: we can use three lines of code:

UserManager userManager = 
    new UserManager(new UserStore());

userManager.RemovePassword(userId);

userManager.AddPassword(userId, newPassword);

It's probably better to use the answer that EdwardBrey proposed and then DanielWright later elaborated with a code sample.
