How can PHP developers ensure secure authentication processes without compromising sensitive data?

To ensure secure authentication processes without compromising sensitive data, PHP developers should use secure hashing algorithms like bcrypt to store passwords in a hashed format. They should also implement measures such as salting passwords and using HTTPS to encrypt data transmission. 

// Hashing and salting passwords using bcrypt
$password = 'password123';
$salt = '$2a$12$' . substr(str_replace('+', '.', base64_encode(random_bytes(17))), 0, 22);
$hashed_password = password_hash($password, PASSWORD_BCRYPT, ['salt' => $salt]);

// Verifying hashed password
if (password_verify($password, $hashed_password)) {
    echo 'Password is correct!';
} else {
    echo 'Password is incorrect!';
}
