What are the potential pitfalls of using randomly generated passwords in PHP applications?

Using randomly generated passwords in PHP applications can lead to weak or easily guessable passwords being generated. To mitigate this risk, it's important to ensure that the generated passwords are sufficiently complex and secure. One way to achieve this is by using PHP's password_hash() function with the PASSWORD_DEFAULT algorithm, which generates a secure password hash.

$password = bin2hex(random_bytes(8)); // Generate a random password
$hashed_password = password_hash($password, PASSWORD_DEFAULT); // Hash the password securely
