Poor Password Security
- Mistake: Storing passwords in plaintext or using weak hashing methods compromises security.
// Mistaken code
$password = $_POST['password'];
- Correction: Implement strong hashing algorithms like bcrypt or Argon2, along with enforcing password complexity policies.
Syntax:
$options = ['cost' => 12];
$hashedPassword = password_hash($password, PASSWORD_BCRYPT, $options);
