Passwords That Should Never Be Used - How to create strong passwords and hacksafe passwords

Strong passwords are your first step in securing your systems. If a password can be easily guessed or compromised using a simple dictionary attack, your systems will be vulnerable to hackers, worms, Trojans, and viruses.
Trojan, virus, and worm authors have had great success attacking systems with weak and/or default passwords. Take IRC/Flood Trojan for example. McAfee’s virus profile states that IRC/Flood has over 120 variants and has infected over 60,000 machines in the last 30 days. IRC/Flood succeeds by checking for 22 different different easy to guess admin passwords (variants vary). Unfortunately, there are a lot more where IRC/Flood came from, W32/Tzet.worm, W32/Random.worm, and W32.HLLW.Gaobot.gen are in the wild just to name three.
Hackers also have no problem compromising systems with weak passwords. Programs like L0pthCrack for example make the process simple and efficient. Creating a password-cracking dictionary is not even a challenge. Type the words "Creating Password Cracking Dictionaries", without the quotes, in to your favorite search engine. A comprehensive dictionary can be downloaded or created from scratch in short order.
Below is a list of commonly used weak passwords that should NEVER be used. If any of these passwords look hauntingly familiar and are being used, you need to change the password immediately.
I totally agree with this idea but isn't it understood? Most of the webmasters would know this much, atleast.
Last time I visited a friend of mine and when he was logging on to his hotmail ID he was typing his password for a long time and I asked him what was he doing. He told me that he was typing his password consisting of alphabets and numbers that made up to 70 characters. It was one of the longest password I've ever heard of. And you know what he said, his email ID has the safest password.
You could easily use a phrase as a password, and to include numbers in it, use any number as a space (like "this0is0the0safest0password0in0the0world0hurray"). This yaw you wouldn't forget it. Of course you could use a gigantic phrase but I don't know if that is even possible to store in the passwords database..
Other type of password that can be used is the "numb3r5_4nd_l3773rs" type.
Or you can even type a backwards phrase, so the dictionaries wouldn't be able to guess them (like "nac uoy fi em kcah ot yrt")
More importantly than typing in common passwords, is the concept of default passwords. For example, how many wireless products come with default passwords where the owner is too stupid to think to change it. Now people are being arrested for connecting to wireless networks, but I think the fault should be placed on the people who aren't securing those networks in the first place, the product makers.
Also, make use of symbolic (literally, not literary) passwords [^*@&%!!@#$*12342568 9ABCDEFGHIJKLMNOPQ...] arranged into random strings of blah. Takes forever to crack according to this article: http://www.thecrypt.co.uk/lockdown/recovery_speeds.html
it is a good idea all of you gave above.a security password must include number ,letter and symbol...certainly capitalization aslo need not lack.however,it is not a perfection.there is a good way to protect your password.the order of your typing them...you can type the latter part with keyboard then use mouse to input the fore part to avoid some spy software.
i use an alphanumeric combination for my passwords. i tried to open a friend's account using his favorite artist's name and it worked. i told him at once about that, and asked him to change his password immediately or else I would hack his accounts. hehehe he changed the passwords to all of his accounts. some people are so vulnerable to hacking because they use simple words as passwords.

They arn't the best examples of passwords that you should use...
You need Special characters like: @~{}]['#/()*"$%"^! Lowercase Letters like: abcdefghi Uppercase Letters like: ABCDEFGHI Numbers like: 01234567
All this will create the best password for example:
Also that Microsoft password strength checker is a joke. *8IiY^jK is a strong password but neigowpagjioeamdklbewiqoerweoqyirosyireopiytdringiwoeaniinvkdlvdsanioveahgieoaur
eiowqyuqwetuip is not according to it.
Well, actually, I think it uses a simplified version of the KDE algorithm that I posted on page 3. From what I see it works like this:
The base strength rating is 0.
1. If the password contains at least 8 letters, regardless of case, add 1 to the strength rating. 2. If the password contains at least 1 number, add 1 to the strength rating. 3. If the password contains at least 1 special character, add 1 to the strength rating. 4. If the password is longer than 14 characters, add 1 to the strength rating.
5. If the password contains less than 8 of any type of character, subtract 5 from the strength rating. 6. If the password contains only 1 type of character, subtract 5 from the strength rating.
For another suggestion try using very special characters... ones you can only get to by holding ALT and then typing in numbers on the keypad... like this...

{¿äilikepie (that is: ALT+123, ALT+0191, ALT+132, ilikepie)
It creates a very small chance that anyone will even guess to use those... and it will become very difficult to actually figure out what keys to press,etc... it makes it even more secure by including a random phrase such as ilikepie.
Password generators may be fun to play with, but they sure are not useful. Like rvalkass said, it is much easyer to remember a sentance than tK(#n6Kw2z.

Any family related name, or just some plain pets name eg rover123 is far too easy to be guessed. Especially if you use a number that means something and/or known to others.
Once there was a couple, Mickey and Herb, they both starts their day with prayer and continue
praying for every thing through the day. This they have been doing for many decades. Mickey started
to pray for her husband long before she got married. She said, “I didn’t want to make a mistake. I
wanted a long, happy marriage to one man a man who is near to God through his prayer life.” She also
prayed early-on for two children, a boy and a girl. When that prayer was answered she got so excited
that she said, “God tickled my heart real good when He answered that prayer.” Sin....

PHP Links Requirements 1. You should understand the majority of PHP (ex: variables, echo, etc.
www.w3schools.com is a good reference). 2. Experienced with HTML. 3. You need a PHP compatible
server if you wish to see your results. Description One of the major advantages of PHP is the
ability to create something similar to an Iframe, only without the scroll-bar. The main advantage of
this is that you only need one layout page, while the others can be simple 'white space &
content' pages. Another advantage of this is your web site doesn't look like a fi....
