In the last version mr12.5 we increased the security standards for the subscriber's password.
Now it is mandatory to have:
* password length min 12 chars
* must have at least 3 digits
* must have at least 3 lowercase letters
* must have at least 3 uppercase letters
* must have at least 3 special chars
In this review we adapt the random password generator in the CSC.
