Query: An Observation About Passphrases: Syntax vs Entropy   On the premise that we are using passwords composed of multiple English
words, we argue that using syntactically correct passphrases has no significant
impact on the security in comparison to randomly arranged collections of words.
We only analyze the contribution of the syntax itself. A comparison to the
other kinds of passwords is out of the scope.
