How to make and INSANELY secure password

Say your levels have been deleted and you have no idea why. Then people start coping them. To the EXACT feature. WHY? How?
The problem is most likely your password. So lets say your password is "password".
NO!
That is the least secure password. Lets see some tips on how to make the best one.
The best passwords are secure, hard to figure out, but easy to remember.

Good passwords are personal, like a pet. not just the name, but add something after it.

Good things to add are simple words like and, the, for, you, and stuff like that.

For example... you have a dog named Bingo...

It could be andbingo, thebingo, bingoand, and the like. That is simple, and weird, and noone would ever think of it... except now...

Anyways, good things to add are /s or 's seperating leters or words...
b'i'n'g'o or the/bingo and the like.

Capitalizing the entire thing works wonders too.
also adding the number of the month of your birthday is nice too.

So far it looks like this:

AND/BINGO9

why not have some letters be 1337?
AND/8|NG09

There you have it. Any comments or more tips will be appreciated.

I've personally never heard of a case of someone stealing PSN information, then using it to copy and delete levels. Still though, having a secure password is incredibly important. I know that my password is secure because I can tell people everything but the last two characters and they'll still never be able to figure it out without some brute force program to help them.

my password is 5 characters long and has 5 times the charater A in it. But i do not say in which order these characters are

:3

Hmmmmm, you have listed a whole bunch of techniques that security experts would strongly advise against here (personal info, pets names, common words). A lot of systems won't allow for special characters either, especially apostrophies.

This is a tutorial for making a memorable password, not a secure one ;)

Best password is having no password. In other words leaving the field blank. ^.^

Something like this should be good enough: 28wx6np75

PS: Brownie points for anyone who can see the system behind it.

That's not insanely good...that's like...bad.

Seriously, don't use anything anyone else have ever known about.

My password is the same for everything, but I'm genuinely the only person on the planet who could actually know it, or at least what it means :p

mine are a mixture of nonsense words and acronyms, put together to make sounds that amuse me, so I can remember them, despite the meaninglessness of the word. Leetify certain letters and you're done.

My password contains letters, numbers, 1337 :) Pfew im safe
