But if you use 5tl1ylev, it is "simply" a matter of the hash's reverse lookup to get to the password. So, women might disagree, but in terms of passwords, size really matters (at least a minimum size). In other words, I'd prefer 15 a's as password over 5tl1ylev any given day.

Then memorize the password in phonetic form. Example: Password: 5tl1ylev Phonetics: Five - tango - lima - One - yankee - lima - echo - victor I guess you can also write it down on a piece of paper and keep it in your wallet. Then you'll be fine as long as no one steals your wallet and the wife/girlfriend doesn't poke around :) Why not use a password generator like http://www.winguides.com/security/password.php or better yet, download one that runs on your own machine.
