Some math about passwords:
We start with a password using eight characters form a - z (no capitals).
26^8 = 208827064576
This happens when you also use numbers.
36^8 = 2821109907456
This happens when you add common symbols (! " # $ % & ' ( ) * + - . , / [ ] ^ < > { })
48^8 = 28179280429056
This happens when you add capitals.
52^8 = 53459728531456
This happens when you add one single character
26^9 = 5429503678976
Another point -- it can be hard to remember long random passwords, but very long passwords can be simple. If you have problems remembering long strings of random characters, try using random words. At least three or four chosen randomly from a long wordlist. Think of the wordlist as your alphabet. /usr/share/dict/words on Ubuntu has 98569 words.We start with a password using eight characters form a - z (no capitals).

This happens if you choose three words from the list:
98569^3 = 957681397954009
This happens if you choose four words from the list:
98569^4 = 94397697714928713121
But please choose words which do not form a meaningful sentence or are logically connected in other ways, and make sure it is at least 12 characters long in total. "one two three" is a terrible password. "lion Malaysia snow cutlery" is a very good one.
