Is assigning a unique ID to each user enough to secure a login system in PHP?

Assigning a unique ID to each user is not enough to secure a login system in PHP. It is important to also use secure password hashing techniques, such as bcrypt, to store and verify user passwords. Additionally, implementing measures such as CSRF tokens, session management, and input validation can further enhance the security of the login system. 

// Example of secure password hashing using bcrypt
$password = 'password123';
$hashed_password = password_hash($password, PASSWORD_BCRYPT);

// Example of verifying a password using bcrypt
$entered_password = 'password123';
if (password_verify($entered_password, $hashed_password)) {
    // Password is correct
} else {
    // Password is incorrect
}
