you already do remember 26 chars "random" password (Score 1)

Actually everyone of us can quite easily remember 26 characters long random "password". The one we _do_ remember starts with "abcdefg..". If that isn't random (the order of alphabets) then maybe someone can tell us an easy way to conclude why alphabet "a" is followed by "b" and then why it's followed by "c". AFAIK the order of alphabets is just an agreement and could be as well "qwertyuio..". My point is that random passwords can be remembered the same way as the order of alphabets. At least here in Finland kids are taught to remember alphabets by "singing" them in order. Random passwords can be quite easily remembered by the same way. Repeat the characters in your mind (speak them to yourself in your mind) ten times (or something). It's also good way to type the password a few times while repeating it in mind. It's also good to use the password for a few times during the day or a next few. If you can remember the layout of your keyboard then why much shorter random password should be any harder? I do agree that sentences are easier to remember and the xkcd comic has it's point.
