I'm currently using LastPass for a lot of the sites I need to authenticate to (the mobile app is a definite plus). A single English word with numerals (i.e. British12) can be easily hacked. A "pass phrase" is preferable. For example: the password "Brent123" is much less secure than "BrentCorrigan_is1_hot_mother!" However, as has been mentioned above, it requires the site to allow a long password as opposed to a short one.

As much as a password with length 8 and requiring one lower case letter, one upper case letter, one special character, and one numeral sounds nice, it is less secure than allowing someone to enter a phrase of many characters. In fact, a 'short' password with a lot of restrictions, as mentioned previously, is less secure than simply allowing a password of 8 character that can be of any form. (If you want I can show the math. I'm a geeky gay guy.
