What are the potential security risks of using PHP's built-in random functions for generating passwords?

Using PHP's built-in random functions for generating passwords may not provide enough randomness and security. It is recommended to use the `random_bytes()` function along with the `bin2hex()` function to generate cryptographically secure random strings for passwords.

php 
$password = bin2hex(random_bytes(10));
echo $password;
