How can PHP developers ensure compliance with banking website terms of service regarding session management and login behavior?

To ensure compliance with banking website terms of service regarding session management and login behavior, PHP developers should implement secure session handling techniques, such as using HTTPS, setting secure flags on cookies, and implementing strong password hashing algorithms. Additionally, developers should enforce strict login behavior, such as limiting login attempts, implementing two-factor authentication, and regularly auditing user sessions.

// Start a secure session
session_set_cookie_params(0, '/', '.example.com', true, true);
session_start();

// Set secure flags on cookies
ini_set('session.cookie_secure', 1);
ini_set('session.cookie_httponly', 1);

// Implement strong password hashing algorithm
$password = password_hash($password, PASSWORD_DEFAULT);

// Limit login attempts
if ($login_attempts >= 3) {
    // Lock account or implement CAPTCHA
}

// Implement two-factor authentication
// Code to send SMS or email verification
