The question needs to be more specific. There are many different types of attacks for finding passwords: social engineering, birthday attack, dictionary attack, man-in-the middle, brute force, etc. etc. etc. The "How" is different for each attack.
Bruteforce
no. you either earn them or use a gameshark. the passwords are for "*character name* combo" moves. they're all the same thing: they use the 3 basic attacks of their significant character, and then finish with a stronger attack, varying which character. for example, Sonic combo finishes with a shot attack, while Shadow's finishes with the basic heavy attack (Chaos Nightmare) as far as colors go, though, there are no passwords. passwords are only for combos =(

Dictionary attack

Any password is vulnerable to a number of attacks. With hashed passwords it depends on a number of issues;What is the length of the keyCan the attacker gain control of the hashesYou could use a brute force attack, for example. Hashes can be particularly sensitive to attacks utilizing rainbow or pre-computed hash tables as well.
No. It is a carnivore, but it will only eat meat if it finds meat. It will not attack or kill prey for meat.

Power-On passwords, Drive Lock passwords, and passwords used to authenticate users.
Generally the brute force attack is least effective since it has to try all possible combinations and lengths as it guesses possible passwords. Attacks like dictionary attacks are far faster for passwords that are vulnerable since far fewer combinations need to be examined. The strongest passwords can only be cracked using the brute force method and if they are long enough, the length of time necessary to crack them exceeds the length of time that the gaining access to the system would be valuable - and possibly exceed the lifetime of the system!

The possessive form of the plural noun passwords is passwords'.Example: All of our passwords' security is a top priority.
