Alexander,

     >>> Which password length is more secure - that is a question.<<<

If you used the above statement, just as you typed it, as your password (passphrase), would it not both much stronger than 6 characters and very easy to remember?

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.
