Missing user password in Parse log in - ios

Question

Below is my code for phone number verification. First we query to check if user already exists; if so, I want to log in with that user. If not, I create a new PFUser.
- (IBAction)confirmButtonTapped:(id)sender
{
// Check to see if a valid phone number is entered
if ([self.phoneNumberTextField.text hasPrefix:#"+56"] && self.phoneNumberTextField.text.length == 12){
self.phoneNumber = [self phoneNumberWithoutSpaces:self.phoneNumberTextField.text];
// Check if phone number is already assigned to a Parse user
PFQuery *phoneNumberQuery = [PFUser query];
[phoneNumberQuery whereKey:#"phoneNumber" equalTo:self.phoneNumber];
[phoneNumberQuery findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error){
if (!error){
if (objects.count > 0){
// Move on to main tab bar and log in with user found
PFUser *user = [objects objectAtIndex:0];
[PFUser logInWithUsernameInBackground:user.username password:user.password block:^(PFUser *user, NSError *error){
if (!error){
[[NSUserDefaults standardUserDefaults] setValue:[NSNumber numberWithBool:YES] forKey:#"recoverUser"];
[[NSUserDefaults standardUserDefaults] synchronize];
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:self.phoneNumber, #"phoneNumber", nil];
[PFCloud callFunctionInBackground:#"sendVerificationCode" withParameters:dict block:^(id object, NSError *error){
if (error){
NSLog(#"Error calling cloud function: %#", error.localizedDescription);
}
}];
[self performSegueWithIdentifier:#"confirmNumberSegue" sender:self];
} else {
NSLog(#"Error logging in: %#", error.localizedDescription);
[[[UIAlertView alloc] initWithTitle:#"Connection Failed" message:#"Please try again." delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil] show];
}
}];
} else {
[[NSUserDefaults standardUserDefaults] setValue:[NSNumber numberWithBool:NO] forKey:#"recoverUser"];
[[NSUserDefaults standardUserDefaults] synchronize];
//Create new Parse user
[self createNewUser];
}
} else {
NSLog(#"Error fetching user object: %#", error.localizedDescription);
[[[UIAlertView alloc] initWithTitle:#"Connection Failed" message:#"Please try again." delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil] show];
}
}];
} else {
[[[UIAlertView alloc] initWithTitle:#"Invalid Phone Number" message:#"Please enter a valid phone number." delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil] show];
}
}
I am getting a Parse error when trying to log in (Code: 201) Missing user password.
