Abstract
Using an empty string as a password is insecure.
Description
It is never appropriate to use an empty string as a
password. It is too easy to guess. Empty string password
makes the authentication as weak as the user names, which
are normally public or guessable. This make a brute-force
attack against the login interface much easier.
