BAH! WRONG! Random letters and numbers are not the safest choice at all. They are the least safe choice possible, because they're impossible to remember, so you have to either save them in a file or keychain somewhere or write them down, and then all a hacker has to do is find where you *put* it, as opposed to wildly guessing any one of a genuinely infinite number of possible words, phrases, dates or ideas that you can easily keep only in your head. No one is going to guess the name of your neighbor's dog growing up or the first words you said to your high school crush; anyone can read the little post-it note of "A44s63qrzy" you have stuck to your monitor so you can freakin remember that shit. I hate the perpetuation of that stupid, stupid, inane, stupid concept that a random password is more secure. It leads to password programs that reject anything resembling dictionary words and force millions of people to write their passwords down or use easily-guessable shit like "qwerty123."
