What potential issues can arise from not encrypting passwords in a PHP login script like the one discussed in the thread?

Storing passwords in plain text in a PHP login script can lead to serious security vulnerabilities. If the database is compromised, attackers can easily access user passwords and potentially gain unauthorized access to accounts. To mitigate this risk, passwords should be securely hashed using a strong hashing algorithm like bcrypt before storing them in the database. 

// Hashing and storing the password securely
$password = $_POST['password'];
$hashed_password = password_hash($password, PASSWORD_DEFAULT);
// Store $hashed_password in the database
