To all those who use a word for their password, for your own sanity, toss a number and shift-number in there somewhere. It makes your password orders of magnitude harder to crack. Although the best overall protection is password length.
An easy to remember password that has many characters is impossible to guess, and impossible to crack with brute force (due to having to test every password shorter then yours first), like so:
'Thisismypassworditisreallylongandwilltake500yearstobruteforce!'
On the other hand, you don't want to use the same password everywhere:
'Thisismyothermypassworditisreallylongandwilltake500yearstobruteforce!'
Why don't you want to use the same password in multiple places? Because if the site gets hacked or has to store your password in plain text for some reason (some sites that tie in third party services like Teamspeak servers have to save the original passwords), then you can be sure someone will try that password on your email account and other places they can guess.
For anyone who is curious, we don't store any passwords, just checksums based on them. Also, we have thousands [http://gyazo.com/27f06a62ddf94963cba8e5969e15b322.png] of people using the same couple passwords. So many people get "hacked" in various situations from having a password that is just a word or a name. It makes me sad.
As far as what I use, my current passwords typically have the domain name in them for length, and then a mix of numbers and symbols that are different for each site to some degree. My non website passwords tend to be random gibberish based on mnemonics to help me remember them. Or generated with nifty programs like APG [http://www.adel.nursat.kz/apg/]
Too many passwords? Using Post-it notes? Grab a copy of KeepPass [http://keepass.info/features.html] and play with it to see what you think. It's free, EXTREMELY portable (you can keep a backup copy of your heavily encrypted and passworded database on your email account or web server somewhere), and you can run it straight off of a USB stick or something.
