What are best practices for securing a PHP website with passwords to ensure a seamless user experience across different devices?

Securing a PHP website with passwords involves storing passwords securely, using strong encryption methods, and implementing password policies to ensure user accounts are protected. To ensure a seamless user experience across different devices, it is important to use responsive design techniques and consider implementing features like password reset functionality and multi-factor authentication. 

// Hashing the password using bcrypt
$password = $_POST['password'];
$hashed_password = password_hash($password, PASSWORD_BCRYPT);

// Verifying the password
$entered_password = $_POST['password'];
$stored_hash = ''; // Retrieve stored hash from database
if (password_verify($entered_password, $stored_hash)) {
    // Password is correct
} else {
    // Password is incorrect
}
