Remember though, length trumps character set. Every bit worth of entropy you add doubles the search space. A password of twelve, random lowercase letters is tougher to crack than an 8+4, or even a 10+4. Especially if the latter isn't completely random.
If using a pass phrase, remember that languages are based on predictable patterns. In terms of being difficult to crack cryptographically, a word usually provides roughly the same entropy as a randomly-chosen letter. (So you'll want a minimum of eight words, twelve is better, thirty is best if you can.) The added length does, however, put your password out of reach for any unsophisticated brute-force algorithms that don't use word dictionaries, so there is still some benefit.
For unique website passwords, take a hash of the website name (simple character-substitution or reordering hashes are sufficient for this and can be done in your head, on-the-fly) and add an 8-10 character random password. The random password may be reused between sites as the hash will be different, and all total it will be long enough to be difficult to crack if the password database is stolen.

Thanks ramesh it is very usefull information.
One can use following simle linux command to create complex password:
< /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c${1:-20};echo;

Another way to remember your PW is to have a Song or a phrase and taking the first or last letter of each word (replacing a with @ or something different) like:
You to me are everything the sweetest song that I can sing:

Best guide I read so far! And I have read lots (and written some).
Some more tips for remembering passwords:
1) change passwords separately, non all at once
2) type passwords manually until you remember them (don't c&p)
3) use pleasant sentences or memories linked to the asset protected by the password: they are is easier to remember and trigger pleasant feelings when typed :-)
4) a 14 character lowercase password is more robust than an 10 character one with mixed case, numbers and digit (24^14 vs 78^10) see also xkcd 936

I accept every thing in this article , but we need to move on higher end cryptology password generator,
if i suppose give my password is : passw0rd
P means q ( whatever you assign instead of P )
w means x (whatever you assign instead of W)
but you have to set the correct password for this reminder one thing don't forget the password this is high end method crptology .
