Are there any specific security considerations to keep in mind when implementing a login script in PHP?

When implementing a login script in PHP, it is important to consider security measures to prevent unauthorized access. One common security consideration is to hash passwords before storing them in the database to protect user information in case of a data breach. Additionally, using prepared statements to prevent SQL injection attacks is crucial to ensure the integrity of the login system. 

// Hashing the password before storing it in the database
$password = password_hash($_POST['password'], PASSWORD_DEFAULT);

// Using prepared statements to prevent SQL injection
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username AND password = :password");
$stmt->bindParam(':username', $_POST['username']);
$stmt->bindParam(':password', $password);
$stmt->execute();
