One time I used an uncrackable 35+ character password. Though the purpose of it being so long was that it was the password to my school site where my Dad could check out my grades. It involves using all the letters on the keyboard up to the "seed" password, alternating between capital and lowercase letters, and if there are any numbers, converting them into pseudo-binary. This means that the relatively insecure password "password123456" would be "QwErTyUiOpqWeRtYuIoPaQwErTyUiOpAsQwErTyUiOpAsQwqWeRtYuIoQwErqWeRtYuIoPaSd011000111100000111111" Such a password is impossible to remember if you don't know the original password or the formula, requiring those who don't know it write down the password in long form, and since it's so long, it makes entering it off a piece of paper even more of a chore. Finally, since it has so many characters, it's so secure it's ridiculous! Yes, what this all goes to show you is that preventing your parents from seeing your grades will turn you into a security expert.
"Sisters, you know only the north; I have traveled in the south lands. There are churches there, believe me, that cut their children too, as the people of Bolvangar did--not in the same way, but just as horribly. They cut their sexual organs, yes, both boys and girls; they cut them with knives so that they shan't feel. That is what the Church does, and every church is the same: control, destroy, obliterate every good feeling. So if a war comes, and the Church is on one side of it, we must be on the other, no matter what strange allies we find ourselves bound to."
