Common misconceptions with password security:

* concatenating words together is more secure == false. Modern attacks use a dictionary of words and tries combinations of such words concatenated.

* using txt spk / l33t style words are harder to crack than common words == false. Modern dictionaries have every imaginable combination of number and non-alpha/numeric substitutions of letters as well as plain English words.

* using non-English words are more secure == false. Dictionaries include words from most languages, proper-nouns and even slang that isn't technically part of any language.

Password cracking has come a long way in the last few years and current security advice hasn't kept up with development.

Use lower case: 26 possibilities
Use upper case: 26 possibilities
Use numbers: 10 possibilities
Use punctuation: 32 possibilites
Use them all: 94 possibilities per character

Using English is the easiest way to fall victim to dictionary attacks. Put in another language and suddenly the cracker would have to include 20+ dictionaries. Put in a dialect and the cracker would need to put 2000+ dictionaries in.

How can you possibly claim that increasing the possibilities is _not_ more secure?
