Answer 1

You should use findOne on model to return userObject. Then you can update the object that was found like regular javascript object and save it with .save function.

User.findOne({email: xyz, password: req.body.password1}, function(err, user){
 if(err)return handleErr(err);
 user.password = req.body.password2;
 user.save(function(err){
    if(err)return handleErr(err);
    //user has been updated
  });
});
