Yes, it's four digits. But it's also a month (there are only 12) and a year (which most likely is less than a few years later than today). Therefore comparing four digits representing a date with a random group of four digits without apparent meaning is a bit weird. Also, I'd remember the date as January 2012 and not as Oh-One-One-Two. > A 16-digit number, a four-digit number and a > three-digit number turns into a 23-digit number.

As you wrote in another message: This doesn't come for free. One has to train this. FWIW, I have a fairly complicated totally random 20-character passphrase (letter, digits, symbols) which I have memorized pretty quickly after using it for a few days having to type it each time I start my computer. (I memorized it without using any of those techniques I referred to above.) Then again, I can't really tell you this passphrase. I can type it (with all 10 fingers) but I couldn't tell it to you without simulating typing it. Maybe I'm a freak of nature. :-) Or maybe that's just how 10-finger-typing works. Regards, Ingo
