How to reset password with UserManager of ASP.NET MVC 5

Question

I am wondering if there is a way to reset password with UserManager of ASP.NET MVC 5

I tried this with user that already has a password but no success. Any clue?

IdentityResult result = UserManager.AddPassword(forgotPasswordEvent.UserId.ToString(), model.ConfirmPassword);
if (result.Succeeded)
{
       //
}
else
{
        AddErrors(result);
}

Answer 1

It is here ASP.NET Identity reset password

UserManager<IdentityUser> userManager = 
    new UserManager<IdentityUser>(new UserStore<IdentityUser>());

userManager.RemovePassword(userId);

userManager.AddPassword(userId, newPassword);

Answer 2

I suppose this is newer but there is such an API in Identity 2.0:

IdentityResult result = await UserManager.ResetPasswordAsync(user.Id, model.Code, model.Password);

model.Code is generated the following way, and you should send this as a link in a email to make sure the user who is claiming to want to change the password is that one that owns the email address:

string code = await UserManager.GeneratePasswordResetTokenAsync(user.Id);
