Also substituting letters with symbols will help, for example:
And then william sayed:"I really hate cake!"
Change the 'a' to @ and 's' to $
And then willi@m $ayed:"I really hate cake!"

And then william sayed:"I really hate cake!"
plus a dictionary attack also has a lot of problems with dialects and slang, so in order for a dictionary attack to be successful they must use a tool that uses some kind of AI. At least that is what i believe, please correct me if i'm wrong, my experience with dictionary attacks are not that great. Alex ----- Oorspronkelijk bericht ----- Van: "Alexander A.

Hi Dave! Yes, it's very easy to remember, but I think this method for password setting is not as strong as it may appears :-) The phrase "Which password length is more secure - that is a question" contains not 58 "random chars", but 11 only, because each word must be considered as a single symbol in the vocabulary, say for brute force attack. There is a strong corelation between the chars inside of the words if these words are taken from our lexicon. So, these characters should not be considered independent. Yes, this password is long but it is not too random, and so it is not too secure. Moreover there may be found efficient heuristics when you try to attack passwords like human speech sentences due to existing correlation between words inside of such sentences and due to quite deterministic structure of sentences. If you bring some order (the way for easy memorizing) into your password you decrease it's strength. Well, and now try to type above phrase in invisible mode and don't make mistake :-) Though, IMHO six chars passwords are too short. I like at least 8 :-)

First of all regardless of your password length, it only cares about the first six characters. Even more insane is it doesn't matter what case of the letters are, it will allow you access all the same. On top of this, theres a bug in the iPhone app which will not allow you to unsave your card number. Its a good thing they guarantee 100% of your money against fraudulent transfers, because its only a matter of time.Hello. IMHO "shockingly laxity" is not as obvious as it may appear at first approach. Six chars give us about (26+10)^6=2 billions of possible passwords. If their server is smart enough to allow as low as 1 authentication attempt per second for the same account then you will spend some hundreds years trying to brute force it. BUT! The short password can be easy memorized, when the long password must be recorded somewhere (sometimes in very inappropriate place), and then may be stolen. Which password length is more secure - that is a question.
