Quick check on this one that I am trying to figure out. First of all I want to apologize if I hurt your eyes with my code, I just started two weeks ago with php and I am trying my best applying the logic :-D
So 2 factor was just implemented via user profile, meaning that if the feature is still not enable the user can still login successfully, after the 2 fact is enabled then he will be redirected to verify the code. with that said the login.php post will need to check the following:
'''
$email=mysqli_real_escape_string($db,$_POST['email']);{
$password=mysqli_real_escape_string($db,$_POST['password']);
$stmt = $db->prepare("SELECT password FROM users WHERE email = ? AND isEmailConfirmed='1' AND is2facEnabled='0'");
$stmt->bind_param("s", $_POST['email']);
$stmt->execute();
$stmt->bind_result($hash);
//checking hash
if ($stmt->fetch() && password_verify($_POST['password'], $hash)) {
$_SESSION['email'] = $email;
header('location: prod.php');
'''
If I remove the password check below then it works but it never checks if the password is correct, if I leave it how it is then if I put a wrong password the page refresh with no errors and goes back to enter credentials. I think it has an issue with the $_POST but not sure.
elseif (!$stmt->fetch() && password_verify($_POST['password'], $hash)) {
header('location: login2factorverification.php');
}else {
array_push($errors, "Incorrect credentials or email needs verification");
enter code here
my question is, how do I accomplish these checks and login properly, thank you in advance.

This basically amounts to what I consider the first rule of programming: Break The Problem Down.
Rather than trying to write one piece of code that checks user existence, password, and 2fac status, do one at a time:
