What are some common pitfalls to avoid when developing a login system in PHP?

One common pitfall to avoid when developing a login system in PHP is storing passwords in plain text. Instead, passwords should be securely hashed before being stored in the database to prevent unauthorized access to user credentials. 

$password = 'password123';
$hashed_password = password_hash($password, PASSWORD_DEFAULT);
echo $hashed_password;
