NOOOOO!!!!

Surely it's obvious why this would be a BAD password. It's based on a
dictionary word, with simple, common letter substitutions. This is the
only the next step up (common permutations) from a plain dictionary
attack. If you're going to use "h4<Km3" as a password, expect to get
hacked.

Don't base your passwords on dictionary words, phonetic misspellings,
names, slang, etc. They're all well-known. Use something properly random;
I usually do a 'strings -8 /dev/urandom' and then pick something from the
first screenful that I think I can memorise. I know people advise never to
write down passwords, but I do and keep it down the back of my cellphone
for the week or so it takes me to memorise it. IMHO that's still a LOT
safer than having an easily-cracked password. But DON'T write it down on
a post-it note behind your monitor or under the keyboard!!
