How can the variables "passwort" and "neuespasswort" be properly compared in the provided code?

The variables "passwort" and "neuespasswort" should be compared using a secure method such as hashing both passwords and comparing the hashed values. This way, the actual passwords are not stored or compared directly in plain text, enhancing security. One common hashing algorithm for passwords is bcrypt. By hashing both passwords before comparison, you can ensure that the passwords are securely compared without exposing the actual values. 

$passwort = "user_input_password";
$neuespasswort = "new_user_input_password";

// Hash both passwords using bcrypt
$hashed_passwort = password_hash($passwort, PASSWORD_DEFAULT);
$hashed_neuespasswort = password_hash($neuespasswort, PASSWORD_DEFAULT);

// Compare the hashed passwords
if (password_verify($passwort, $hashed_neuespasswort)) {
    echo "Passwords match!";
} else {
    echo "Passwords do not match!";
}
